Wearing lens for more than 2 weeks??

I have worn 2 week lens for a month numerous times with no noticeable negative effects. Does anyone else do this and what are your thoughts on it?

Hi Brian,

Please do not wear your contact lenses for longer than they are designed to be used.

There's another post here on Lens 101 that gives several good reasons for this, but I can't seem to find it right now. Look around and see if you can, but in the meantime, remember that just because you don't feel any pain doesn't mean that no damage is being done.
When you wear your contact lenses for too long, they're more difficult to clean, and that can lead to infection.
Also, contact lenses don't last forever, and when you over-wear them, there's a risk of one or both of them tearing in your eye, and getting a piece of a contact lens out of your eye isn't easy. It may even require a trip to the Emergency Room.

Probably your best bet would be to ask your doctor how he or she feels about you wearing your two week contact lenses for a month.

Take care and thanks for asking.

Eagleye

Have you ever heard of "corneal neovascularization"? It's a condition in which blood vessels begin to form over your cornea, the clear "bubble" over the front of your eye. Corneal neovascularization is a common condition in people who wear contact lenses, and you can't see these blood vessels without special equipment. They don't hurt or obscure your vision until it's too late and your very eyesight is in jeopardy. Even if they are detected in time to save your vision, they never go away. If your eyes recover and blood stops flowing through these new blood vessels, they still show up on examinations as "ghost vessels." They are there forever.

This is just one of the many reasons why contact lenses like Acuvue Oasys were designed to be worn for two weeks tops if you don't sleep in them. Your eye doctor isn't just making this stuff up. There's a reason why these are called "two week disposable" contacts and not "change them when they start hurting" contacts.

I will be honest, I have worn my lens for 30 days at a time for the last 4 years or so. If it were causing a problem wouldn't my eye doctor notice it and let me know when I have my yearly exams?

It's not worth the risk. Stick with the replacement schedule recommended by the doctor that can examine your eyes and see exactly what condition they're in.

I dont know much but I had Accuvue Oasys yesterday from the leading biggest optics shop in my city and they are accuvue's authorised dealers here and they told me that that there is no harm if use for 30 days. Infact they recommend me to use it for 30 days and then use new after 30 days period. But if u can afford its better to change after two weeks. I bought one pack having 3 Pairs and they clearly told me that one pair will last for 30 days without any problem but u should remove them and store before sleeping. If u continuously wears it then they dont last long.

Hope u would find ur answer.

attention:

acuvue brand, soflens 59, soflens 66 is recomended to use for two weeks in developed countries. but in the developing countries, such as china, malaysia, they are recomended to use for one month!

so why can not acuvue oasys be used for one month in those countries?

I bet it has something to do with the laws in various countries. In developed countries they have stricter laws than in so-called developing countries.

I don't understand why people are willing to risk their EYES because they don't want to replace their contact lenses so often. Some may say that there's some kind of "scam" going on, but I don't think so.

Let me put it to you this way. If it turns out that you're being "scammed" and you're buying more contacts than you need, so what, you've lost some money.

If you decide that you're not going to give in to the "scam artists" and wear your two week contacts for a month, you could damage your eyes. How much money is your eyesight worth? Would you rather lose money or eyesight?

It's your choice. If you're so paranoid about being scammed, there's always glasses.

don't misunder stand my meaning, i never suggest anyone to over use their contact lens.

i' just angry about some lens companies, especially bausch & lomb. it's nothing about the laws in those poorer countries. the most important reason is that the consummers in those countries don't earn as much money as thoes who are in us, europe, japan, hongkong, singarpore, take china for example, most contact wearers still use traditional lens, when they first hear about monthly replaced lenses, they will all be surprised: wow, one pair for only one month?! so expensive! no more than daily lense!

take b & l for example:

optima 38, in us is recomended to use 6 months, in china 1 year.

soflense 59, in us 2 weeks, in china 1 month.

soflense 66, in us 2 weeks, in china 1 month.

soflense 66 toric, in us 2 weeks, in china 1 month.

sequence, in us 1 month, in china 3 months.

soflense 38, in us 1 month, iin malaysia 3 months, china 6 month!!!!!

everyone knows that the air environment in china is much worse than us and eu, but in china b & l all make the wearing period much longer.

why?

if they recomend to use the lens as long as in us and eu in those developing countries, very few people will buy!

this is why b & l has already discontinued its traditional lens in many rich countries, but sitll sell a lot in those poorer conutries.

Really? Does CIBA Vision or Vistakon (J&J) do the same in developing countries? If so I would stop buying from them. I hate such kind of unethical business.

Now hold on. Don't be so quick to cry "unethical" because you read one post on the Internet. We all know that every word on the Internet is 100% accurate, right?

Before you go boycotting anyone, do some research of your own from reputable sources. Try going to the library instead of surfing the net.
If you're afraid of being taken for a fool by those Big Bad Corporations, it's just as bad, if not worse, to be taken for a fool by someone writing a post on the Internet without the aid of Big Bad Corporate Spin Doctors.

I don't know how true alecchong's accusations are, and I'm certainly not calling him/her a liar, but I'm going to do some of my own research before calling anyone unethical.

Would you care to tell us where you got your information from, alecchong?

ciba vision is good, its wearing period is complete same in rich and poor countries! johnson only makes its "acuvue brand' one month to be worn in china, two weeks in other rich countries. other johnson's lens, acuvue-2, acuvue advance, and acuvue oasys, all the same wearing period in both countries.

bausch & lomb is the worst, except pure vision, most of its lense have "multiple standard" in different countries---not based on the consummer's eye health, but their income!

alecchong · #14 (**permalink**) 10-19-2008, 01:13 AM

Woud you care to tell us where you got your information from, alecchong?[/quote]

hello, i just want to claim that "i've never learned these information of the wearing from internet!"

----all i learned from the real life, from the officials of bausch & lomb and johnson & johnson in some different countries!

i was born in china, now studying in college in malaysia.

i began to wear contact lens when i was in senior middle school in china. soon i became very interested in contact lens, i collected some information from professional books, advertisements of the lens companies, eye doctors , opticians and so on.

i first noticed the wearing period is different is the year 2003. than time in taiwan, b & l employed a local pop team s.h.e to advertise. i noticed that soflens 59, in taiwan, is recomended to use for two weeks, at the same time, in china mainland, soflens 59 is recomended to use in one month! i continued to check the official website of b & l in taiwan and china, later found that not only soflens 59, but soflens 66, toric, soflens 38, and sequence, the wearing period is all different, generally, in china is two times longer than taiwan.

later i fonud not only b & l, but also j & j, j & j's acuvue, in china is recomended to use for one month, but in other rich countries is only two weeks!

for this i called the official customer service line of both b & l and j & j, both of them gave the same explanation: we don't care how long the wearing period in other countries, we have already done enough medical experiment in china that to wear for one month won't damage your eyes.

yeah, their standar in china is only "won't damage your eyes"!

later i had travelled to hong kong for times, i went to ask some professional opticians there, found that the wearing period there is the same as in taiwan and us, almost only half of it in china.

in 2006 i came to malaysia to study in college, i found that in malaysia, soflens 56 and 66 toric is also recomended to use for one month, the same as china. but soflens 38 here is recomended to use for one or three months, different from china, in china is six months!

since malaysia is also a developing country, but a bit richer than china, not as rich as its neighbour singapore and other westen countries.

the most funny is that, in singapore, soflens 56 and 66 toric is recomended to use for two weeks. as we know, singapore is quite near malaysia, it takes only 1-4 hours to drive to some main cities of malaysia. and the climate, the air environment, and the people's living habbit is almost the same in the two countries, then why b & l recomends the different wearing period in the two coutries? -----although the climate, the air environment, and the people's living habbit is almost the same , the average income is different!!!

generally, i find out a rule of theses lens companies, especially b & l, its wearing period in each country is not based on the consummers' eyes, but their income!

their standard in rich countries is "to be most comfort", but in poorer countries is "won't damage eyes"!!!!

Hi,

I'm an international student so you can understand why I'm pretty sensitive if big companies are doing more harm than good in developing countries. I'd never worn contacts until I came to the U.S, so I don't know about the situation at home. I heard about some cases similar to what alecchong just told us, but always thought it's the cunning sellers who tell lies to boost their profits, not the big corps who have a double standard for different countries.

Having said that, I did an online research and found alecchong's accusations to be true. I went to B&L's Chinese website, looked for Soflens 59 (here: http://www.bausch.com.cn/2007new/blprodution_body.asp?ID=18) and translated it into English with Google's translation tool. Yes, the lens' usage time is extended to 1 month in China. Then, I found something called Soflens Quarterly. Having never heard of it before, I googled it and it turned out to be the Soflens 38 (Optima FW) which can be used for only 2 weeks here in the US. Worse, Google gave me same results with B&L India, B&L South Africa (they are in English so everybody can read easily!) As for J&J, their products have the same replacement time in different countries, except Acuvue (what is called Acuvue Clear in India.)

Is that enough? I hate companies that hold people's health so cheap.

And I feel lucky that my Rx is Focus Night & Day.

Update: I've found out that CIBA Vision China recommends 1-month replacement for O2Optix, in the US it's 2 weeks. So I won't have any contact lens to wear if I decide to boycott these companies.

yeah, b & l do this in many poorer countries!

but i just want to tell you, j & j's acuvue is different from acuvue clear.

you can easily find the info of acuvue in j & j's official website, it's the word's first disapossible lens. its central thickness is only 0.07 mm, oxygen factor is 40 dk/t.

acuvue clear, maybe not sold in us, the central thickness is 0.105 mm. oxygen factor is 28 dk/t, is quite similar to j & j's discontinued lens survue, since it's a bit thicker than acuvue, so it's easier to hold on, is suggested to first time users, and its price is also lower.

acuvue and acuvue clear is both sold in china. since acuvue clear is not sold in us, we can not compare. but it's a fact than j & j make the wearing period to one month in china, in us only two weeks.

last, ciba vision o2 optix, in its us web site it says the wearing period can be two weeks or one month, depend on the custmers' opticians' suggestion.

3 weeks plus one day and I am rubbing my eyes a bit at night, threw them out and starting a new pair tomorrow...

chemist · #18 (**permalink**) 02-20-2009, 10:36 PM

there has been no scientific evidence provided in this thread that confirms any health issues with extending the wear times. there do seem to be posts designed to frighten people. If there are specific peer-reviewed reports, please provide them.

in the mean time, assuming you are using a hydrogen peroxide based daily disinfectant, lens material does not appear to degrade with 1 month use.

it is possible to see clarity falling off as protein deposits build up. fortunately, there is a product "unizyme" that you can use once a week or two that breaks these down.

( I'm not associated with the company in any way )

hi,
im new in here, as i have read the posts i leard a lot from it. before i don't have any idea about contact lenses simply because i haven't try it, even once. im just thankfull that my eyes are clear, and i don't have any problem in it. but im very much curiose how it feels when we're using contact lens.

eyeC · #20 (**permalink**) 02-28-2009, 10:40 PM

Hey all, I am new here and am new contact wearer at age 50!!! I got tired of trying to find my reading glasses so decided to get contacts. I am now using the Acuvue Oasys after trying Acuvue2, Precision UV, and B&L Multifocals! All within a month!!!
I loved the Acuvue2 but heard about Oasys and the doc said he didn't care if I tried several different brands before I decided. So that is why I did. In my Acuvue Oasys one eye is for reading (2.50) and the other for distance(1)(which isn't too bad).

Now....here is what the doctor said about Oasys.
The Oasys CAN be used for one month with NO PROBLEMS!!! They are the EXACT same thing as the Oasys that is recommended for 2 weeks!!! The main reason for wearing for 2 weeks instead of one month would be protien build up on them. He is very knowledgable and been in the business for over 30 years! So....he is getting a years supply of "2 weeks" but told me I could wear them for a month at a time (taking them out at night) and it should not be a problem! That way I get more for my money thru insurance.

The only thing I noticed about the Acuvue compared to the B&L is that the first time I put in the Acuvues....it stung! I mean right away stung....then it went away after a few minutes. Anyone else have this?

Thanks in advance for any info or hints to a new contact wearer!!

sunshine4 · #21 (**permalink**) 04-29-2009, 09:12 PM

When I ordered mine, the eye doctor said not to wear them over the 2 week period. Then my order didn't come in and I asked if I could get another trial pair since my order wasn't in. The lady at the desk said not to worry, they can usually be worn up to one month if you dont' sleep in them.

I agree with Eagleye. No matter what the Internet opinion is, I would recommend you follow your doctor's advice. You may even want to get a second opinion. If you can get two doctors who have actually examined your eyes to agree that for your particular set of eyes, wearing two week lenses for a month is okay, who am I to argue with medical professionals that have personally examined you?

Yes, of course. Why bother even seeing the doctor when you can just get medical advice from The Lady at the Desk?

She said that she has worn hers for a month and no effects. I think that it was just the excuse given since mine were suppose to be in within a week and it was over 2 weeks late.

angel0310 · #25 (**permalink**) 05-25-2009, 07:29 PM

My eye doctor told me that if I was not sleeping in them that they could be worn for a month not 2 weeks and I have been doing that over 2 years now with no problems. Right at the 3 and a half week to 4 week mark they get uncomfortable. Remember they were made to wear for 2 weeks 24 hours a day except when you wish to refreshen them.

painkill · #26 (**permalink**) 07-12-2009, 09:21 AM

hi.

i'm from Turkey and i can say there are no two week lenses in my country. all of them daily, monthly and annual.

acuvue series are sold as montly lenses.

bfralph · #27 (**permalink**) 07-20-2009, 04:27 PM

I am back to trying contacts after a two year layoff. Many years ago I used Focus Toric lenses as my first disposable lenses and they were originally rated for quarterly replacement schedule. When they changed to monthly I spoke to my doctor and he said the lenses hadn't changed and if 3 months was no problem then that was OK.

My next lens was the Acuvue Advanced Toric that were rated 2 weeks but I usually got 1 month out of them.

I now am on my first pair of Acuvue Oasys Astigmatism and the doctor of course wrote 2 week replacement schedule. I told him that I intended to go one month with them and he said if there was no discomfort that that was OK just dont go past one month.

My invincible son has Softlens 58 soft lenses that are rated monthly and he goes upto 5 months before replacing them. Yikes!

the real criteria for determining the length of wear time for a contact lens?? All this discussion about wear time and being scammed and different times for different countries for the same lens....... what is the real criteria for determining wear time from the manufacturer??

I think the "real criteria" here is what your own doctor has to say. If he or she examines your eyes and tells you you can wear Acuvue Oasys contacts for a month, then I would say get a second opinion, and if you get two doctors telling you that you can wear them for a month, then I think you're okay to follow their recommendations.

I think that's a perfectly reasonable course of action, Railfan. If you can find two eye care professionals who independently agree that you can wear Acuvue Oasys or any other contact lenses for a month, even though they're marketed as two week lenses, then I don't see any reason why you shouldn't.

Until you do that, it really doesn't do much good to come here and cry "scam!"

rfriel asked "what is the real criteria for determining wear time" for your contact lenses, and those criteria are determined by your eye care professional based on the condition of your eyes.

Thanks for the affirmation, weirdscience.

Is there anyone here who has been told by their eye doctor that it's okay to wear Acuvue Oasys contact lenses for 30 days?

Anyone? Anyone? I'd like to get to the bottom of this. If people are wearing their contacts too long, they should know to stop it. If they're replacing contacts too often and wasting money, they need to know that too. Who can give us an authoritative answer?

I don't know if I would trust someone who sells contact lenses to tell me how often to change them. It would be different if I were buying a T-shirt or a pizza, but contact lenses . . . ?

My first thought would be that if I were selling contacts dishonestly I would tell them to change them more often then they should so they can buy more.
Then I thought about it again and if my customer thought that changing their contacts every two weeks was too often and wasn't going to buy anything, I might tell them that they don't have to go through the hassle of changing contacts so often. Cha-ching!

rfriel · #34 (**permalink**) 01-29-2010, 11:43 AM

give me a manufacturer basis for determining wear time? some say 2 week, some say 1 month, where the he!! did they get those figure, a dartboard? the wear time came from a math equation, internal manufacture research, or a dartboard, so why cant the manufacture just cough up the info and let us decide for ourselves. and dont tell me i cant understand it, that's BS, usually when someone says i cant understand it, they are hiding behind known faulty assumptions that they dont want reviewed so they copt out and say it's too complicated, when they actually know their just a bunch of dumb F**KS. and they are full of $hit but dont want anyone to know.

that's like NSA saying to a 5 year old, " we are taking possesion of your popsickle in the interest of National Security for reasons you woudn't understand". the 5 year old should say, GO F*** yourselves........ VIS A VIS, give me a good reason for doing something, AND I'll do it!! otherwise go to he!!, and just saying i told you so is BS and wont cut the mustard.

Hi EyeC. I'm a little confused here. You sound like you're saying that Oasys contacts are the same thing as Oasys. Of course they are. Acuvue Oasys contacts are designed to be worn for 1-2 weeks. Which monthly lens are they supposed to be exactly the same as? I want to check it out and see if that's true.

Your doctor may have told you that you can wear these contacts for a month, but I don't want people reading this post and trying that on their own without talking to their doctor first.

we're all shooting from the hip here, cause the manufacture wont divulge the basis for determining wear time. all the OD can do is say, "this is what I see...... " yada, yada yada, doesnt have anything to do with weartime. the copt out is " my OD told me so, " or " the manufacture told me so",, what a cheap copt out.....

OH NO, what iFFFF the OD is wrong?" what's you do then?

My next lens was the Acuvue Advanced Toric that were rated 2 weeks but I usually got 1 month out of them.

I now am on my first pair of Acuvue Oasys Astigmatism and the doctor of course wrote 2 week replacement schedule. I told him that I intended to go one month with them and he said if there was no discomfort that that was OK just dont go past one month.

My invincible son has Softlens 58 soft lenses that are rated monthly and he goes upto 5 months before replacing them. Yikes!

why the 2 year vacation from contact lens? allergies, work, contacts suck, presbyoipia, health, cancer (j/k) ?? could be many things, but what??

Chemist, would you care to provide specific peer reviewed reports that say that you can wear 1-2 week lenses like Acuvue Oasys contact lenses for a month without any damage to your eyes or any other ill effects? I'm assuming that since you asked for such evidence to the contrary that turnabout is fair play. Can you provide the evidence you asked for?

I believe the phrase you're looking for is "cop out." That's when you don't really know the answer to a question and so you just say that there is no answer, or that you got your answer from someplace else.

The manufacturer will tell you that the wear time is based on the material the lenses are made of, as well as how well they allow oxygen to pass through to the wearer's eyes. That's easy enough to find out on the manufacturer's websites. That's not a cop out.

Saying "that's what my OD told me" is not a cop out. It's the best source of information you can expect about your contact lenses. I'd certainly trust the word of my eye doc over those of some stranger on the Internet who has not earned a doctorate of any kind.

Should I believe you over my eye doctor and the manufacturers of the contact lenses?
