I dont know much about it. I do know that many eye doctors and retina specialists sell specialized pharmaceutical grade vitamins for the eyes that seem to work. I saw them for many different conditions. Starting with a nutrient approach to slow any erosion is not a bad idea.
I had dry eyes to the point of it being daily, bothersome, and giving me a glassy-eyed look. The first step, which alleviated the problem, was taking an eye vitamin heavy in Omega 3’s. Now I just take regular 3’s and it is fine. Try to call an eye specialist and inquire.
Hatzlacha!!!
