That's my first time to wear lenses but I can't see well with them. I used to see well with the glasses even the old ones but the lenses are different. Need your advice.
I went to the ophthalmologist and had a thorough eye exam - I have worn contacts for ages, went to the optician with the prescription from the ophthalmologist, he fitted me for contacts and recommended Day & Night (or the other way around) and for whatever reason I said, sure, I'll take them. ...
Hi, I know this has nothing to do with teens but it's the only thing close enough to the question. I have contact lenses I am having a trial week and the only problem is I find it hard to put the lenses in and take out. I have tried many ways but none seem to work. ANY IDEAS?! :confused:
