I have had eye issues since 1988 losing the sight in my left eye to opticneuritis leaving the right eye to do all the work and being a hairstylist this was a challenge since using TWO FEATHERS internal and external for 4 weeks I have regained my distance sight back .................to me this is a wonderful bonus thanks Robert Roy P.S. the original reason I took this to start with was for a small cancer spot on my face and to detox .....face has healed nicely and detox is still on going!
