Pros: NONE

Cons: Blurry, creates buildup

I have had these contacts for at least a year, when i wear the trial set given to me by my opt they are perfect, no issues except when they need to be cleaned. When i put a set in from one of the boxes I purchased, I have nothing but issues. My eyes blur up, there is a lot of protien build-up, the contact sticks to my eye lid and when i blink the contact lifts with my eye lid, I also can feel the edge of the contacts in my eyes and sometimes it feels like something is poking my eye. Even after I take the contacts out my eye continues to produce protein build-up. NO matter how often i clean them or put drops in my eyes the problems are still there for at least a few hours. I will be contacting my eye dr ONCE AGAIN to see about switching brands.

Pros: They never dry out, You can wear them as you sleep

Cons: none

My old contacts would get dry as early as 6pm sometimes. These never dry out. It's probably bad for me, but I only take them out and replace them when my eyes feel tired, usually after more than a month of constant in-time. I'm not encouraging others to do that, but it proves how well these work on my eyes. Simply amazing.

Pros: Great for masochists

Cons: Burn, baby, burn!!!!

Does anyone know of any lawsuits? Our Chicago attorney has been playing hardball with their New York attorneys whose very weak claim is that the FDA approved them. They even act like they know nothing of a recall. I have been to 2 opthalmologists and have not been able to wear contact lenses in over 2 years since my eyes were damaged. I am 20 years old, an athlete, and a highly competitive scholar. Some of these web postings are obviously monitored by Ciba as you can tell by their reviews. What are they so afraid of? That a group should rightfully sue them? Contact me at hakallal@gmail.com. I would love to hear from you.

Pros: Comfortable, do not dry out, long lasting

Cons: None

I've worn contacts for about 13 years. For most of those years I struggled with contacts that were uncomfortable, and never fit well. This may have been due in part to my astigmatism. I had all but given up hope of ever being able to find contacts that truly seemed to disappear in my eye. But recently my eye doctor recommended I try these, citing they were some of the best contacts on the market today for those with astigmatism. She wasn't lying! It's amazing the change that has occurred with these lenses. No more rewetting drops throughout the day, no more constant blinking and messing with my contacts. When I put them in, they feel like there are no contacts in my eyes. I am so grateful that I have finally found these contact lenses!

Pros: All day comfort without the protein buildup - CRISP vision

Cons: Doctor was hesitant to let me try them.

My doctor seems to be a big believer in the Acuvue line. As a result, I've been suffering through one version or another for the past several years. These lens are COMPLETELY different. No more dry eye issues. No more foggy vision. No more protein buildup. I've even retired my little bottle of Pataday to the back of the medicine cabinet.

Pros: trial lenses are great

Cons: poor optics, dry eyes, foggy after a few days

I rated these too soon. The trial lenses are great but as soon as you buy them, they are totally different. The ones I tried on from the doctor had crisp optics and were very comfortable. As soon as I bought a box of these, I noticed they were different. The optics are horrible and they make my eyes very dry and tired. Don't be fooled by the trial lenses. They ARE different! Don't waste your money buying these.

Pros: Comfortable, Tinted make it easier to handle, AWESOME OPTICS

Cons: none

I wanted a silicone hydrogel lens and tried focus night and day, purevision and acuvue hydraclear (too big) Then, I tried the O2 Optics and LOVE them! I can go all day without using drops or anything. What I like best is I have astigmatism and with these lenses, I can see almost as good as my glasses without needing torics. The optics on these are amazing!!!!!

Pros: none

Cons: red eye dry eyes burn itchy

only ware for 3 days went back to av2 these fucking suck some one shoot the maker

Pros: ?

Cons: Burning, discomfort, dryness

These contacts are very uncomfortable for me. They frequently make my eyes burn, especially when I put in a new pair. I do use a computer a lot but they are dry and uncomfortable. Towards the end of the two weeks they get especially bad in terms of discomfort. I can't wait to get out of these contacts and into a different brand.

Pros: Great by the end of the day

Cons: No toric, requires special solution

Ive been in glasses for 16 years, and been wearing contacts on and off (mostly off) for 5+ years. I stuck with glasses mostly because most contacts bothered me after a few hours, became dry and itchy. I sit in an air conditioned office at a computer all day, and live in AZ with extremely hot dry climate. I never thought I'd be a contact lens wearer because of this. I tried focus monthlys and acuvue advance, b/c of slight astigmatism, and found them just too uncomfortable to wear. My optometrist suggested silicone hydrogel 02 Optix for eye health and the itchyness problem at the end of the day. I noticed they felt a bit thicker at first, but after a week, im in LOVE with these! No itchyness! I'm waiting for the toric to come out soon, because my vision is 20/25 with the spherical. Looking forward to trying out the toric! I'm officially a contact lens wearer now!!!

Pros: n/a

Cons: 5 severe eye problems in 2 months! 0 using my old contacts!

Eye irritation that lead to heavy eye watering and extreme light sensitivity. Could not even leave the house for a day at a time... could not close my eyes without them watering and hurting. It was miserable! I've been wearing contacts for 14 years... never had these kind of problems. Have read reviews elsewhere from people claiming these have caused them temporary or even permanent corneal damage... NOT including lot numbers that were recalled. My contacts were ALSO not included in the recall list of numbers. Don't even waste time with these nightmares!

Pros: they wear well

Cons: give you constant eye infections

It never fails, I get an eye infection if I go 1 day over the recommended 2 week wearing period. I have never been so dissatisfied with lenses, I hate I allowed my quack of a Dr. to talk me into these!

Pros: Very good long term wearability

Cons: none

I was worried based on some of the reviews here but I asked my optician and she said pretty much all her patients wear these for a month. I love that I can wear these for days on end. I average about 4-5 days between taking them out. They are so comfortable it doesn't feel like you're wearing contacts. I do notice some mornings, it takes a few minutes for them to get back to 100% comfortable but that's probably becuase of normal eye goo. No other problems whatsoever. I definitely recommend.

Pros: Don't know they're even in

Cons: dry at the end of the day

I think 90% of the problems people have with these lenses are casued by using the wrong type of solution. You have to be sure and use a solution that says "Ideal for silicone hydrogel lenses" or something to that effect. These things are great, I just bought a years and a half supply and i couldn;t be happier.

Pros: less red line in eye

Cons: dries out

Good contaclens. No problem except when I wear them for a lot of hours for example 10-12 hours a day. One drop of solution and the dryness is gone.

Pros: actually wearable without torture

Cons: Toric can be hard to find, but it exists!

I started out with contacts wearing B&L Purevision monthlies. The problem was that in this country, there was a limited selection of toric lenses, and the doctor felt these would be the most comfortable. She herself preferred Air Optix (as it's known here). I've gotten along ok with the Purevisions for the last couple of years, but while they are very thin, they feel thick on the eye and, I'm getting out the re-wetting drops within minutes of putting them in. They just became too painful to wear, even new out of the box. I thought about just going back to glasses, with dailies as an option, but then I saw Optix toric lenses on the price list, and decided to give them a try. Once I was fitted, these were just a revelation. They feel like... nothing. I can wear them on windy days, in and out of buildings, at home watching tv, and they just feel like I have normal eyes. I haven't touched re-wetting drops since I got them, although it would be no shame to need some during a long day. In short, the best I can say is that I had planned to get fitted for new glasses as well, but there has simply been no need. Thank you, Cibavision!

Pros: none

Cons: uncomfortable, dry, itchy

My eye doctor reccommended these a year and a half ago and I hate them. I can hardly wear them throughout the day. My eyes become dry and tired. My vision becomes blurry and I get headaches. I'm going to the doctor tomorrow and will be getting Acuvue Adavance, which is what I had prior to 02 Optix.

Pros: comfortable, not irritating

Cons: none

My doctor started me with Av oasys, which cause my eyes to itch badly, especially at the end of the day. Then he gave me Pataday 0.2% drops to decrease the "allergies". Prior to that I used AV Advance. I only had o2 optix for one week, and I like it. Sometimes I even forget that I have them in my eyes. I take them off at night and put them back when I get up. So far so good!!!!!! And the price is much cheaper. Make sure your place matches prices, unless you order on line, I found them in Costco for 16.85 per box.

Pros: none

Cons: all

I got the worst infection from these lenses.

Pros: Easier to handle, they don't dry out as quickly.

Cons: Stinging, watering, redness, and more stinging!!!

I started wearing these lenses last summer, and was surprised to find that my eyes would often sting and burn when I wore them. The stinging almost always goes away after the first 3-4 hours, and after that I found I could wear them longer than my old lenses before they dried out. But the morning stinging eventually made me go back to wearing my old brand. I went to my optometrist yesterday for a regular exam, and he wants me to try these awful lenses again, because they are just "better for your eyes". Sure enough, today I am sitting here with that old stinging, watering, and burning sensation again - these things are horrible!

Pros: Like having my natural vision back

Cons: Can be difficult to remove (I'm new at this though)

After reading so many negative reviews here I felt I had to weigh in with my own experience, even though I'm completely new to contacts and have no experience with any other brands. In fact I'm still wearing my trial pair, and will probably aim for my optometrist's recommended replacement schedule of 25-30 days. After thinking more and more often about getting contacts I finally went for it recently and was fitted with a pair of O2 Optix. As for an adjustment period, I could hardly tell they were there as I walked home from my fitting. Let's say 15 minutes, then. That felt pretty good to me. I have slight astigmatism in both eyes so I'm not quite as crisp *most of the time* as with my specs (I now notice subtle changes throughout the day that I suspect I was oblivious to before). In all, very natural feeling with no sense of anything being in or on my eye. No tiredness at all at the end of the day - it's more a question of 'well, I suppose I ought to take them out now.' I cycle quite a bit and I find that the wind irritates and dries my eyes more now than before. It was a problem anyway though and I've now solved it with a pair of UVEX 'Fury' goggles - recommended for anyone with a similar issue who's not happy with the coverage of cycling-specific sunglasses. I was thinking that I'd wear contacts part of the time, specs part of the time but for an 'investment' of 2 minutes morning and night it has hardly seemed worthwhile to wear the specs. I am really wowed by this product and am so glad I didn't have to suffer through earlier generations of contact lens. These lenses definitely work well for me.

Pros: n/a

Cons: corneal scratches

I wore O2 Optix for a year with no problems. Last year I went in for my eye exam and got them again. Three months later I had a very red eye that was weepy and very irritated. I stopped wearing the lenses for a couple of weeks because of this and it went away. The red eye problem continue to occur so I went to my doctor who gave me some antibacterial drops to start with and said if they didn't fix the problem then to go to an opthamologist. Well, it happened again and it turns out that my contacts were scratching my corneas which, after having read the recall notice, was caused by the lens not moving correctly with my eye. The difference being that I purhcased my lenses in June, not September. The eye doctor had to put me on steroid drops for my eyes which are fairly harmful to them, but I had to heal the tears. DO NOT BUY THESE LENSES. I understand that they have "fixed" the problem, but I will not go back to them. You only get one pair of eyes and I'm not messing with them.

Pros: cheap

Cons: rash, itchy eyes, red, what is up with these?

I used to wear these contacts no problem, I read through the reviews and I agree, I think something changed! I thought it was my makeup, solution, even maybe my soap! Nope, it's the contacts! I am now wearing my glasses til I figure out a new contact. I am scared about all the issues lately with contacts. If you have a problem, take them out for sure. I will post when I find a better pair! These might work for some people, but not me. I have really sensitive eyes though, so maybe that has something to do with it.

Pros: Good oxygen flow / Reduce Red eyes

Cons: Some discomfort

When I first started wearing these lenses they seemed perfect and great! It reduced my eye redness alot and was very comfortable. Now ive noticed that these lenses arent so great after all. I dont know if its because of the contacts but i now have a frequent residue that forms in my eyes (you know that stuff most people get in their eyes when they wake up with in the morning), only now it seems to form throughout the day, and whats worse is that it sometimes gets stuck on the actual lens which blurrs your vision! Ive also seen reviews that had this same problem so its not just me! Anyway, there great at first but I believe it all depends on the individual.

Pros: Comfortable

Cons: Cost for Toric

Finally they came on the market, unfortunately not many people carry them yet.

Pros: good vision correction, supposedly healthy eyes

Cons: burning, irritation, itching

These contacts are not comfortable. I've used the correct type of lens solution and worn them properly, but they never feel right and tend to make my eyes water. I've been to two different doctors who tried to get me to buy these but they are not the fantastic lenses that they would have you believe. I think its kind of strange that some seem so bent on getting their patients to wear these (See the review by the assistant to a doctor). Not sure what's going on with that. Reading the reviews, it seems that you either love these or hate them so obviously they must work for some people. I wouldn't recommend them to anyone with eyes that are at all sensitive though. And again, for people who like to post saying that others aren't using them correctly: I used the recommended solutions and used them as instructed. I've been wearing lenses for a long time and tried many different brands but these just did not work for me.

Pros: Good oxygen transmissibility

Cons: Tend to dry out quickly in extremely dry environments

I switched to these (silicone hydrogel - lotrafilcon B) lenses from B&L Soflens-66 (alphafilcon A) and noticed an immediate improvement in comfort, especially in how my eyes felt at the end of the day. There was a brief adjustment period (a few days) before they felt completely natural. The O2 lenses feel 'slipperier' when wet, which may be why some people complain they're hard to work with. The texture and comfort does seem to change over the life of the lens, though - the first day or 2 are often the most slippery and least comfortable. I also find that a pair will get noticeably uncomfortable after 2 weeks (my optometrist recommended they be changed every 14 days anyway). They also feel different depending on how humid the environment is - they seem to dry out quickly in my dry office building, even w/rewetting drops. I rarely have the same issues in other settings. Finally, for those people experiencing extreme or frequent discomfort...just stop wearing your lenses already. Different manufacturers will fit differently, and the same brand won't feel the same on everyone. A good optometrist will re-fit you until you find something comfortable and safe, often at no additional cost. They'll often also exchange the unused portion of your old lens order, so you shouldn't have to sacrifice eye health and comfort just to avoid 'wasting' a little money.

Pros: Comfort after first few days

Cons: Very uncomfortable when I put in new pair

I really like these contacts except for the first few days. They are awful and they have a completely different texture after I have worn them for a few days. No one seem sto know why this would happen. I did notice that someone agreed with me in their review.

Pros: Cause severe eye infections, all were called and pulled off.

Cons: Cause severe eye infections, all were called and pulled off.

Medical Device Recall v02, Page 1 of 5 January 12, 2007 IMPORTANT ￢ﾬ DEVICE PRODUCT RECALL ATTENTION: EYE CARE PRACTITIONERS, DISTRIBUTORS, RETAILERS O2OPTIX￢ﾢ (lotrafilcon B) Soft Contact Lenses CIBA Vision Corporation is conducting a voluntary recall on select lots of spherical O2OPTIX (lotrafilcon B) soft contact lenses in the United States and other countries. We are taking this voluntary action because we identified that some lenses in these lots may fall below our standard for ion permeability, a material characteristic that correlates with lens movement on the eye. Reduced ion permeability in O2OPTIX (lotrafilcon B) lenses may lead to reduced lens movement, symptoms of discomfort and/or foreign body irritation. The potential medical safety risk to consumers posed by lenses with reduced ion permeability includes discomfort, foreign body irritation and superficial localized corneal staining. The possibility of occurrence of these findings is moderate. As with any staining of the corneal tissue, the risk of corneal infection is somewhat increased, although the probability is remote. This recall only affects the O2OPTIX (lotrafilcon B) lenses identified below. No other CIBA Vision product is affected by this recall action. This voluntary action is being conducted in the United States with the knowledge of the U.S. Food and Drug Administration. The affected O2OPTIX (lotrafilcon B) lenses were distributed between September, 2006 and December, 2006. The lots affected in this recall are all lots numbers starting with 6644001 to 6721262 with expiration dates starting from 2011/09 to 2011/11, and lot numbers 6626127, 6636101, 6637017, 6637019, 6637103, 6640120, 6640124, 6642109, 6642119, and 6643080, all with expiration dating of 2011/08 (detailed in the attached table). We are asking that you locate and return these lenses from your stock in accordance with the attached instructions. We recognize the inconvenience this causes you, your staff and your patients. However, this action reflects CIBA Vision￢ﾬ"s commitment to high quality standards and ensuring that our products fully meet your expectations. You will receive a separate communication regarding O2OPTIX (lotrafilcon B) supply shortly. Please feel free to call our Customer Service Department at (800) 241-5999 or your CIBA Vision Sales Representative should you have any questions or concerns. Sincerely, William D. Schaeffer Global Head of Quality CIBA Vision Corporation Medical Device Recall v02, Page 2 of 5 IMPORTANT ￢ﾬ DEVICE PRODUCT RECALL O2OPTIX￢ﾢ (lotrafilcon B) Soft Contact Lenses CLINICAL ASSESSMENT FOR THE EYE CARE PROFESSIONAL Ion permeability is a measure of the ability of sodium ions to permeate through a contact lens material. It has been shown, along with other factors, to correlate with lens movement on the eye, which is an important fitting characteristic. The O2OPTIX (lotrafilcon B) lenses with reduced ion permeability, subject to this recall, may cause reduced lens movement in some patients, possibly causing discomfort and/or foreign body irritation, usually within the first 1 to 4 hours of wearing the lens. Superficial, localized corneal staining may be observed in symptomatic patients. The symptoms diminish quickly upon removal of the lenses. In addition, signs and symptoms usually resolve in 2-24 hours. If the same lens is replaced on the eye, the same symptoms will typically reoccur within a very short period. The potential medical safety risk to consumers posed by lenses with reduced ion permeability includes discomfort and/or foreign body irritation and superficial localized corneal staining may be observed. As with any staining of the corneal tissue the risk of corneal infection is somewhat increased although the probability is remote (see summary table below). Medical Risk Probability of Occurrence with Reduced IP lenses Discomfort and/or Foreign Body Irritation Negligible Moderate Superficial Localized Corneal Staining Low Moderate Corneal Infection Moderate Remote Foreign body irritation and corneal staining are expected non-serious events for routine contact lens usage and can occur for various reasons, such as dust or particulate matter, lens tears or other mechanical type effects. The foreign body irritation that may result from lenses with reduced ion permeability increases in intensity while the lens is worn, necessitating prompt lens removal. The Package Insert and Patient Instruction Booklet advise practitioners and wearers to remove the lens in cases of such irritation. Wearers are advised to seek professional eyecare evaluation if the symptoms persist. No serious adverse events related to this issue have been reported on a global basis. We are presently aware of only seven (7) non-serious product complaints which are likely related to the use of O2OPTIX (lotrafilcon B) lenses with reduced ion permeability.

Pros: eyes feel more awake and refreshed

Cons: do take some time to adjust to

So this review is kind of in response to Mike C. I first got a trial pair of these and absolutely loved them. I had been using Acuvue 2 for ~6 years before and they dried out so quickly and kept fogging up. I had to keep putting eye drops in my eyes. Also, as a college student, I couldnt help but occasionally nap in them which was becoming more and more of problem. So O2 Optix was a refreshing change and I really enjoy the ability to nap in them comfortablly and to occasionally sleep in them. But now I ordered them online and the packaging is different; it says "spherical" on the lens case itself instead of o2 optix. I literally just put them in and am feeling more discomfort and blurriness then I was before. I thought that maybe the online company jipped me but now I am wondering if it is just new packaging. Anyone else get this new packaging? And have you experienced noticbly more discomfort with them?

Pros: small

Cons: eyes are dry and chafing no comfort

Ive had 02optics for a while and have found that there 5 times more breathable technology only makes your eyes feel dry and more irritable. rinsing them does not help. If you are in an air conditioned building it is much worse. dont buy these contacts. Ciba visions fresh look coloured contacts are not only cheaper but feel much better

Pros: comfortable, usually

Cons: First day or two of news ones are awful

Does anyone else find these lens awful the first time you put in fresh ones? It seems like it takes a couple days for them to get focused. I don't change them like I should for that reason alone. Once I get them in for say, a week, then they are wonderful, but that first couple days... :-(

Pros: Very comfortable, moist, good vision, affordable

Cons: Recent recall.

I work for an optometrist. O2 Optix is his preferred lens, to the point it's the only we stock. I know there have been issues with the recall, but it was for the good of the patients. If you have problems with the contacts 1.you are wearing the lenses in manner inconsitant with what your doctor recommended, or 2. your doctor doesn't know how to fit them properly. The guy who said he puts them then takes them out a week later-WRONG. These are not extended wear lenses. If you need to sleep 7 nights in a lens you should have been fit in Focus Night and Day. If they burn, check you are using a solution that is approved for silicone hydrogels-not some store brand generic. And finally not every lens works for every person. If you don't like them TELL YOUR DOCTOR.

Pros: Can wear them for a long period of time.

Cons: none

I've tried every contact out there less the torics, and I have never found a more comfortable pair of contacts. My eyes feel great wearing these

Pros: extremly comfortable, no more dry eyes :)

Cons: none

I have never been able to use contacts, they bother my eyes badly, however, my eye doc gave me a pair of these O2 Optix and my golly, I can wear them :) I love them!!!

Pros: feel great and work great

Cons: Ordering these contacts is a nightmare.

I can't seem to get these contacts. I will not be getting Optix 2 the next time i go in for an exam. I ran out of these contacts at the end of Dec 06. I tried to order more but after waiting for 3 weeks was told they were recalled. Eventually i found a sample pair to use and have ordered through another place. Still no contacts (end of march of 07) It ridiculous. They should take them off the market if they cant fill the orders.

Pros: Gets oxygen to the eye

Cons: Dry Eyes - Uncomfortable - Burning - Itching - TERRIBLE!

Why try lenses that make you want to scratch your eyes out immediately?! I've never had such a bad experience. Some days would be good. I would put them in my eye and a week later I would take them out. I don't recommend this, BTW. But some days would be bad. I would put them in my eye (brand new lenses) and within an hour I was itching and rubbing my eyes like crazy. [No, I don't have allergies.] I finally pinpointed it to be the polymer that these lenses were made of - the body tends to reject it because of the material they use - NOT ALL LENSES ARE MADE OF THE SAME STUFF! I can't stand these lenses and would consider burning a box in effigy if I could afford the matches after buying these worthless tools.

Pros: none

Cons: painful, dry, uncomfortable

I have been wearing contact lenses for 20 years and have never had any issures with them. Since wearing the O2 Optix my eyes have been red, super dry, very blurry, and I always feel like I have something in my eye scratching it. It finally got so bad I went to the eye doc. I have never been happy with these lenses and was not happy to find out there was a recall on them an no one bothered to call or check and see how my eyes were doing.

Pros: none

Cons: pain, blurry vision, contacts leave residue in eyes

My lots werent' recalled by ciba... so i guess i'm stuck with them till i can go back to the eye doctor in april. The ones for my left eye were good for the one that the doctor gave me, but the ones i got from my packages have been horrible. I've been wearing contacts for about 15 years now, and I haven't been able to wear these for more than one evening once a week for about 3 or 4 months now. Sever pain, blurry vision, residue left in my eyes.. red eyes.. dry eyes... DO NOT GET THESE

Pros: WHITE EYES

Cons: can't wear continuously

These lenses are 'fahbulus'!! Best thing I've done for my eyes in a long time.

Pros: Said Goodbye to Dry with these

Cons: Can't think of any

Tried OASYS and ADVANCE. Snap - Haaated them. These are AWESOME - wear all day, no dryness, no discomfort.

Pros: COMFORT

Cons: only a 2 week lens

These lenses are just great. As a new wearer, my Dr tried me in just about everything. Advance, Purevision, Oasys -- hated em. ProClear was OK but couldnt sleep in them, did not want to pay price for Night and Days. Couldnt be happier with these.

Pros: Comfort, Vision

Cons: Zero

LOVE this lens. My Dr has a set of the O2 Optix Toric and trialed these on me since I have astigmatism in one eye. Oh my God, these are sooooo much better than Acuvue Advance. never going back to Advance. It gunked up and clouded my vision after 3 days.

Pros: Price, Comfort, Vision

Cons: Zip

Lenses feel great. Saw some stuff on recall, gotta believe in company that would recall millions of lenses for comfort problems. Can't wait for them to get back up to speed and out again. Wearing DAILIES right now and they are OK, LOVE the O2 Optix.

Pros: Comfort, Cost

Cons: None

Read the second post below me and right away could tell the problem. Poster said used saline. Must not have listened to their Dr. Mine stressed saline was not acceptable except as rinse. It had no disinfecting property. These have been absolutely the best lenses I have ever worn. Tried the others - Advance, ProClear, but these trumped them all on comfort.

Pros: Best Lens ever Worn

Cons: None

No problems with wearing the lens. Have slept in them with no problems or having to remove them.

Pros: None

Cons: Red irritated eyes, burning, blurred vision

These are the worst contact in the world. I stopped wearing them 6 months ago. Finally went back to the eye doctor today, and when I told him I want a new brand, he said that these were discontinued! No kidding. The first month I wore them, I almost went blind in my right eye....some kind of infection. Its been constant burning, red, swollen, irritated eyes since the day I opened up the 1st package!

Pros: no problems - love them

Cons: none

I have used Optix2 after trying Frequecy 55. I would not go back. I love these Optix2. Can sleep in them and wake up with no dry eyes are irration. I use Aquify 5 and Visine for computer eyes maybe 1 time a week. If you have problems you maybe have developed an allergy to the material in the contact lens.

Pros: none

Cons: burning eyes

ever since i switched to o2optics i have had nothing but problems , burning eyes even in a brand new pair . Red eyes , watering eyes total discomfort

Pros: none

Cons: I have never had worse contacts!

I have to say I was SO glad to see I am not alone. I usually only wear contacts on the weekends. I bought these in October. I found I could not wear them, they were amazingly uncomfortable. The only difference is my eyes are always red now, even though I don't wear the lenses anymore. I went to the eye doctor, thinking I had an infection and he told me it was allergies (I don't have allergies) and that I probably just could not wear contact lenses anymore! I can see now I'm going to go back and try a different brand. I've been wearing contacts for 23 years, and I've never come across contacts SO bad!!!!

Pros: none

Cons: name it

My sister and I went to the eye doctor together in December. He told us that we both had swollen corneas and that we should use O2 OPTIX. We tried them and instantly hated them. We went back in a week and told him so, and he got angry with us both and said we had to try them again. He refused to let either of us try another brand. I also got new glasses, and am now wearing them all the time. My sister is having the most problems, with white mucous coming out of her eyes and her eyes are bloodshot. We have both had contacts for most of our lives, so it's not like we don't know how to take care of them. I WOULD NOT recommed these awful things to my worst enemy! They are hard to handle, dry out almost immediately, and the solution is pricey.

Pros: none. zero. nada.

Cons: Dried out my eyes within 30 mins of wearing them.

I've been wearing Procon 38 for a year and a half and by the end of the day my eyes would be kind of dried so I thought I'd try out something that would provide more moisture. Upon seeing the O2 optix commercial, I thought these contact lenses would be perfect for me! mann how these ones dried out my eyes -- after 30 mins of putting them on!!! Now i've switched to acuvue advance, which is MUCHHHH better. I would never go near this stuff again!

Pros: Sometimes feels comfortable

Cons: uncomfortable, irritating, sometimes painful

O2 Optix is one of the most expensive brands out there, and I can't see why. It claims to be a soft lens but often, I can feel it in my eyes. It frequently irritates my eyes and floats around. I've just switched to regular Acuvue and it is SO much better and cheaper as well. Acuvue is the way to go. It feels like nothing is even in your eyes.

Pros: none

Cons: Causes severe pain, irritation, dryness

I just started wearing these contacts about 4 months ago, and have decided to stop wearing them all together. I'm back to glasses temporarily until I find a different brand. I wouldn't recommend these to anyone. I even had an appointment with an Ophthamologist because I thought something was wrong with my eyes. After reading the reviews on these contacts, I'm convinced my eyes are healthy (which was the Doctors diagnosis as well)... but the problem is these contacts. Don't buy them.

Pros: good vision!

Cons: dry out!

i was wearing for 3 months. they were good for the first 4-5 hours but after that they were drying out and wouldnt feel comfortable. i changed now to acuvue oasys and they feel great

Pros: OK for the first hour

Cons: dries out really quick and feels like its burning the eye.

I've tried the o2 optix for the first time. I use the prescription 7.0 (left eye) 6.0 (right eye). for the 7.0 prescription, my eye felt irritated after a couple hours. When I tried taking the lens out of my eye, it felt like it was burning my eye. I had blurry vision for a couple hours. I tried soaking the lens in the solution and even trying on a new pair, but I experienced the same problem. I guess this is the batch that was recalled. If they fix the problem, I guess these lenses would be OK.

Pros: Some lenses are comfortable

Cons: Some lenses are not comfortable

CIBAVision has issued a recall of certain lots of O2 Optix lenses. There is an announcement on their website. I think this may be why I was having trouble with the lenses.

Pros: Comfort and lack of eye fatigue

Cons: work best for about 1o days

This is the first contact that works for me. My eyes are dry do to medication and I have astimatism. I am considering changing them every week as I find comfort lessening before the full two weeks time.

Pros: So comfortable Can't even feel them

Cons: Dry at the end of the day, but aren't all contacts?

These are the ONLY lenses my eyes will tolerate and that's just fine by me because I LOVE them! They were recommended to me because they let more air in and let my eyes breathe! They are easy to put in, don't flip, and are so comfortable. I wear them 12 hours plus, some days much longer than that! I've tried a few other lenses since my husband is in the eyecare business and was using me as his guinea pic, but I couldn't tolerate the switch for even a day, since the other lenses felt gritty, very uncomfortable and cheap. In the past I have had minor papillary conjunctivitis and with these lenses the inflammation is practically nonexistent. O2 Optix are a wonderful lense!

Pros: They're comfortable and you can sleep in them

Cons: They're not comfortable at all

Ok, here's the deal with my pro's and con's above. I have been wearing these lenses since last spring and I had no problems until I reordered the lenses in November. The lenses for my right eye came in the same O2 Optix boxes and O2 Optix individual packages and worked great. However, the lenses for my left eye came in individual lens packages that did not say O2 Optix but rather simply said 'Spherical'. The lenses in the new packaging gave me severe pain. So I went back to another lens for my left eye for a month. However, the supply ran out and I tried the newly packaged O2 Optix lenses again for my left eye. Once again, severe pain. Last week I remembered that I still had a box of the original O2 Optix lenses I purchased in the spring and I've been using them with no problems at all. So, have the O2 Optix lenses changed? I see a lot of good reviews for these lenses in the past but now they are not good at all. By the way, the difference in the boxes is that the new boxes say 'contains 6 spherical lenses' instead of 'contains 6 lenses'. More craziness: my eye-doctor and Wikipedia both say that O2 Optix lenses are not spherical but rather are aspherical. I think the lenses have changed. I'd be interested in hearing which packaging your lenses are in and if you've noticed a difference too. Thanks!

Pros: nothing good

Cons: discomfort, burns, eyes get red

discomfort, burns, eyes get red, if I try cleaning it it doesn't work.

Pros: None

Cons: Eyes dry out extremely fast, contacts are hard feeling

I have sensitive eyes and these contacts seem to be hard feeling on my eyes. They stick in one spot on your eye and do not move always when your eye moves. This creates a problem while working or driving. They also dry out my eyes extremely fast and I normally can't wait to take them out when I get home from working only 8 hours. I am going to be changing contacts this weekend. These are a waste of money!

Pros: Nothing

Cons: Most irritating, uncomfortable contacts ever

takes forever to get in, needs to constant re-moisiturizing. total crap. seriously stay away from these and their gimmic, ive had contacts for 7 years, and this is the only brand to piss me off.

Pros: Longer Wear Time

Cons: Took a month or so to get used to them

I first tried these a year ago and hated them. They irritated my eyes, etc. When I went back for my check-up the Dr. told me it was because I was using the wrong cleaner on them. I used to use Renu and it is not made for silicone hydrogel lenses, which is why I had the discomfort. Now I make sure my lens cleaner is safe for silicone hydrogel contacts. Maybe this will help others. I haven't had any problems this go around.

Pros: No Pros

Cons: Cannot see clearly. Dry out my eyes. Irritate my eyes.

I would not recommend these contacts to anyone. I am very frustrated with the "WONDERFUL-BETTER-FOR-YOUR-EYES" contacts. They dry out so quickly--I find myself blinking purposefully just so I can see. (Literally makes for hazardous driving!) My daughter is also trying these out. She is having more difficulty with hers because they tend to flip inside out or fold over or stick to her finger, or mine when I try to help her, rather than to her eye. Visual clarity is awful.

Pros: None

Cons: Make my eyes itch

I hate these contacts...they make my eyes itch..if that makes sense. They are also hard to get in and out of my eyes. I couldn't keep these in for no more then an hour before the irritation started.

Pros: comfortable

Cons: adjustment time

I wore Frequency 55 for almost a decade and my doctor said to switch to these. He says they are thicker, so the eyes will go through an adjustment period. At first, they were difficult to take out and felt funny, but I persisted and now they are great! I wear my contacts all the time - they are very comfortable and never dry.

Pros: None

Cons: Severe pain, swelling of the eyes

I changed my lenses after the pain, I changed the Contact solution and cleaned my container. I do this frequently, so the infection was not caused by poor hygeine.

Pros: Are somewhat comfortable

Cons: Eyes dry out

I have trouble with dryness with these contacts too. I have to sometimes put drops in eyes in order to get them out of my eyes. I have gotten about five pairs that when I put them in they feel scratchy but then later my eyes are hurting so bad that I have to replace the contacts. I see another reviewer has had the same problem with possibly a small tear in them.

Pros: Feels sturdy and doesn't flip inside out

Cons: Makes eyes dryer and so is hard to take out

I heard about these great new healthier-for-your-eyes contact lenses and was excited to try them. At first they felt very comfortable. I also liked that they don't flip inside out. But when it came time to remove them (at the end of the day), it was really hard to remove them, especially for one of my eyes. I thought it was just a fluke but it has happened almost every time. So I'm back to my Acuvue2s and trying to figure out what to do with the O2 lenses I have left.

Pros: "Supposedly "Healthy

Cons: Painful, hard to get in, very hard to get out

I got O2 Optix last week, the first time I started to use contact lenses. At first I thought that I had to get used to the feeling but it turned out that the problem I was experiencing was due to the contacts. Putting the contacts in was hard, because when they had contact with my eyesm they had a slight stinging. Taking them was even worse because they were stuck onto my eyes and it took me 45 minutes to take them out, and the only reason why I did was because I had started to cry! Also, they did not center, which caused me to not be able to see properly (blurry when i looked down) and the entire time, I felt like I had a hair in my eyes. This is why I only wore them for 2 hours!

Pros: Comfort and visual acuity.

Cons: None

Following a minimum adjustment period, I find that the lens has better visual acuity and is more comfortable than any lens Ive worn so far. I wear them continuously for 2 weeks before changing them out. I have found that Blink-N-Clean are the most effective and compatible lens drops. I use them three times a day: AM, late afternoon, and PM. On the infrequent occasion a lens becomes a bit cloudy, I simply remove and give it a quick rub and rinse with Sensitive Eyes saline solution and clarity is immediately restored.

Pros: Not anything that i can feel

Cons: Causes severe dry eyes and some irritation

I switched to O2 optics after 2 years of acuvue. The result, severe dry eyes i developed during the months wearing these. From my experience, this perticular lense didnt feel anymore healthy than acuvue. Beware, dry eyes comes with O2 optics. My guess is that this lense allows way more o2 to come in contact with your eyes to the point you tear evaporate faster. For people with a long history of wearing traditional contacts, think real hard before you buy o2 optics.

Pros: Comfortable to Wear

Cons: Occasionally get a ripped one out of the box

These are by far the most comfortable contacts I've worn as a person that sleeps in their contacts regularly. I usually only take them out to clean and soak overnight once every 2 weeks before replacing. The only downfall is that occasionally I will get one that either already has a tear in it or I put a small tear in it when getting it out of the new wrapper. I'm not sure which is the case. It may be from using my index finger to get it out, but sometimes it is torn when I get it out of the solution. I guess that is the compromise for such thin comfortable lenses. I'm willing to deal with it.

Pros: you can wear these contacts longer

Cons: none

I enjoy wearing these contacts. These contacts are the most confortable contacts I have ever worn!

Pros: Deliver's more oxygen to your eye.

Cons: Don't hold moisture well.

First of all, these are made of some kind of silicone and are thicker than my Acuvue2. I think the thickness makes them harder to handle and somewhat less comfortable on the eye. I loved my Acuvue2, but switched because I found myself over-using my contacts and needed something healthier for extended wear. The best thing about these lenses is that they are more breathable than most other lenses and therefore better for eyes, especially during extended wear. The worst thing about these lenses it that they don't hold moisture very well at all. Even fresh O2 Optix lenses get dry often; and although I would like to, I never sleep in these lenses. If I sleep in them they get so dry that they stick to my eye and scratch my eye upon removal. This can painful & I intend to try another brand the next time I get lenses.

Pros: No complaints

Cons: Comfortable, no irritation.

These are the third brand of contact lenses I've tried. I have very dry eyes. After trying brand number one (not sure of the brand) she sent me home with O2Optix and Advance Acuvue. The Acuvue were as irritating as the original brand I tried, but the O2Optix were immediately more comfortable for me. I can wear them all day and with no discomfort. With the other lenses I had to blink continually to clear a "fog" off the lenses, with O2Optix I dont have that problem, and I don't feel the irritation as with the others. As far as the vision goes, I'm still trying to adjust to monovision, so I do still have some blurr, but it is improving. It is as good as it was with the other lenses.

Pros: Comfortable. Can wear over long periods

Cons: None

Great lenses. Very comfortable. Almost do not feel it throughout the day. I am able to wear it for 12 hrs or more. Highly recommended
