As a visual artist, obviously, eyesight is huge for me. I am grateful that I was born with good sight and live somewhere that I could get help if I had a correctable vision problem. There are many who don't have that privilege. Watch this very moving video (3.5 minutes) about two blind-from-birth sisters whose sight is restored but a simple, quick operation.
Quite frankly, I don't know enough (and couldn't find enough info) on this organization to recommend or encourage donations. While it is, of course, an incredibly worthy cause, I can only say donate at your own discretion.
