We both have cataracts and both have found improvement. My husband recently that his cataracts are practically gone. My doctor tells me that I still have the one but I do see better out of it so I am sure that it has thinned. We have both used N-acetyl carnosine for two years but only use one drop in each eye instead of two that we did for a year. We use now as maintenance and to hopefully keep from having macular degeneration.
