The Saffron MD formula I sort of stumbled on and was very pleasantly surprised. Friends and family would laugh at me wearing my sunglasses a lot but the bright light really started to bother me. Not any longer and many of the irritating light bursts that have recently started happening have reduced to almost nothing. All since I started taking this formula. Yes I have had my eyes professionally checked on a regular basis but they just said I am older and should expect such things. They said my eyes were pretty good for my age. Now finding this formula they are much better.
