I just received a new pair of glasses.  They are transitions with A/R
coating.  I have what appears to be a smudge on my left lens, that is
unremovable through cleaning.  It is only viewable at certain angles

serious treatment during young age, I have no ambylopia, but an

Good Day Folks,
I'm considering getting toric lenses which I'd wear approx. 6

surgery before. The last was in 1988. I have seen double since! The
vision in the right eye is 20/200. What are the chances of making the
right eye perfectly straight? I'm 39 and wear no glasses.

floaters in my eyes [ vitreous degeneration ] , I want to know  about
the risks that  accompany phakoemulsification  with this much of high

Well, I've about reached the limit with bifocals. My accommodation is
now weak enough that I cannot achieve comfortable, sharp vision at both
computer-screen distance and reading distance with a single correction.
I am not at all concerned about bifocal lines being visible. But I ...

Hello to everybody,
I'm 60 years old and french, living in the south of France. my apologises
for my poor english.
Six years ago I had a cataract on my righy eye fixed by the ultrason method.

I bought a couple of boxes of Thera Tears Lubricant Eye Drops that are
expiring on July 2004.  I just got LASIK and use about 5-6 tubes a day
so the boxes will be long gone by July.
I was just wondering if the drops might be less than effective as they

I have a pair of glasses with Transition Lenses.  I was debating on
whether to pick up a pair of prescription sunglasses as well.  i'm

protection.  Is there any added protection with purchasing polarized
