How long can you use 1 year eye contacts??

Post Reply New Topic

How long can I use my one year eye contacts? Because I want to wear them for a one time after they got expired, I don't which brand or quality they're but they're cosplay/anime eye contacts, so how long after expiring can I use them?? I only wore them one time months ago if that counts.

That's hard to say, I guess. I wear my contacts way past their expiration date and I know I'm not supposed to because they/re only good for 30 days. That tends to be my nature anyway. I only had one pair of pants and I wore them for 8 years until they fell apart. The pair I bought 3 months ago will last me for 8 years, I hope, I only keep one pair of pants at a time. Same for sneakers.

I have heard about a case where a girl (my then classmate's cousin) has gone blind in one eye because she didn't use her contact lenses properly. I don't know exactly how she was using her contact lenses to make that happen. Her blindness was caused by some contact-lens-related eye infection.

So, I would be very careful with contact lenses, although many people seem to use expired contact lenses without any problem. If you can, you should avoid using expired contact lenses.

Well, most likely you won't have any problem. But if you do, the consequences can be very severe.

I think old contact lenses can more easily harbor microorganisms and you probably need to expose your eyes to those organisms just once to get the infection. I think in the case that I mentioned above she got some ameba from the lens, which kept eating her eye until she became blind.

So, if you keep using the expired lenses, you had better be extra careful with their hygiene.

Yes, she actually had some symptoms serious enough to prompt her to see her GP (I don't know exactly what symptoms). However, the GP was incompetent and decided it was nothing serious, leaving the infection not properly treated for too long. That's why the ameba infection got bad enough to cause blindness. My classmate told me it could have been treated, if she had been sent to a specialist and got a proper diagnosis. They were even talking about suing the doctor.

Any way, so, if you get the infection, you would definitely notice something wrong.

You'd better not wear expired contact lenses. I always wear contact lenses and know more about contact lenses care.
