Vitreous Separation and Lens
|
| |
Both of my eyes had Vitreous Separations (with small Retinal Tears) 60 days apart. Does anyone have any thoughts on lens for someone with the above problem. My polarized sunglasses are giving me problems. I'm also thinking that if I eliminate bi-focal's the larger lens area will help.

I wore Fluroperm 151 RGP lenses from 1995 until last year when an optometrist recommended that I switch to O2Optix lenses. He said that I would see better with an aspheric design lens.

Gas Permeable Hard Contacts Scratches
|
| |
Hi, When gas permeable hard contacts get scratches. What actually happens to the lens? Can anyone point me to any site with magnified view of a lens surface?
