Burning problems with Coopervision Clearsight 1 day Contacts

crashcrad3 · #1 (**permalink**) 08-28-2010, 10:40 AM

My son has been having problems with one of his eyes burning after putting in a clearsight contact. We are getting at the end of a one year supply. After taking him to a Doctor, we believe that the disinfectant they are using is too strong and is settling in the contact. This does not happen all the time but enough to be a problem - especially on school mornings. Has anyone else had this problem?

Welcome to Lens 101 crashcrad3.

Sorry to hear about your son's problems. The problem is with one eye, correct? In that case it's hard for me to understand why the contact lenses aren't affecting both eyes. That gives me the impression that the trouble is with the eye rather than the lenses.

Tell me more about this "disinfectant." ClearSight lenses should only be worn for one day, so no disinfecting is necessary. You just put in fresh new lenses each morning. Could that be the problem?

one day disposables are packed in saline solution, not disinfecting solution. However, because the saline is buffered, some brands can sting some people. Other than trying a different brand, you can rinse with Lens Plus.

So if a person is having pain with daily disposable contacts, it might be the buffering ingredient in the saline? Isn't something that's buffered supposed to be gentler? Like buffered aspirin?

I've posted some pictures the Lens Plus package so people can get an idea of what they're looking for in the store.

Sorry, where I am Lensplus is different. It's made by CIBA and is non-preserved saline in a spray tin. Any non-preserved saline would be fine. I'm glad you brought this to my attention, even after +25 years I'm still learning.

The term buffering in chemistry normally means an ingredient is added to hold the pH (acidity/alkalinity) at a particular value.

I've always been advised not to mix different lens solutions because the pH can vary from one manufacturer to another.

Buffering is not the same as a solution with an added preservative.

As contact lens Fitter says, best try a saline solution without buffering or preservative if your son has sensitive eyes.

Is this more like what you're used to?

Thanks to everyone for replying. I have been traveling and apologize for the delay in responding. To recap, it does happen occasionally to either eye. What he does now is to open up each single contact case, replace the saline solution so the contacts sit there overnight and then puts them in - in the morning. This seems to have solved the problem. We have ordered more of a different brand but will go for the three months supply versus the year supply. I read where they were having problems I believe in Japan with these which made me curious if the problem was more widespread.

These are ClearSight 1-Day contact lenses? If so I don't understand why you're putting them in a case overnight. 1-day contacts are inserted in the morning and thrown away at night, aren't they?

It doesn't mean the contacts are being worn more than once. What I think is being said is that the lens solution contains an ingredient, which causes an adverse reaction to crashcrad3's son's eyes. So to reduce this problem, he is taking the lens out of the blister pack the day before wear, placing them in a normal lens case filled with fresh unpreserved saline in the hope that the adverse ingredient will be flushed out before wear.

Remember that the Air Optix lenses seem to contain a chemical (1% Copolymer 845) to supposedly improve wearer comfort, but which, for some wearers, makes the lenses virtually unwearable.

Oh, so when you say "the lens solution contains an ingredient which causes an adverse reaction . . . " you mean the liquid in the blister pack these contacts are packaged in?

Yes, that is what it looks like. Everybody's eyes are different, and maybe crashcrad3's son is just sensitive to that one ingredient.

Gee, you must know everything, Mr. Knotlob.

Trixie, don't understand the attitude but Knotlob is right on. Also, the new contacts are here and hopefully that has fixed the problem. Thanks for the posts.

Let us know how it goes. personal experience is very helpful in finding solutions to people's contact lens problem.

Don't be too hard on Trixie. Trixie is a regular poster here and from time to time forum members may take a friendly poke at one another. Nothing malicious about it, but it is difficult to sense the correct emotion in an email or other text message.

If you've been around this site, you know that when knotlob answers a post, you can be sure it's thoughtful, intelligent and well-researched. I think Trixie was being genuine. If Trixie was being sarcastic, I think maybe the picture would have been of a rather different nature.

So, tell me about these "new contacts" that are here.

So how about those new contact lenses? Are they more comfortable for you?

Crashcrad? Hello?

Okay, thanks. Usually when people say "lens solution" around here they mean "cleaning solution." We haven't heard from crashcrad3 in a while, so maybe if he or she is being misunderstood then we'll hear about it.

No word so far. I guess all is well with him or her.

Well, we had to wait a while before we heard back from crashcrad the first time, although that time it looks like it only took a few days. Typically on this forum I have found that no news is usually good news.
