lutein and bilberry are a few things that help I hear exercise also does sometimesthe muscles in the eye may not be very strong due to several aspects . I don't have all the answers however I think that there are different states and conditions of everyone . 1 thing is that there may be a possibility of a parasite in the eye causing a problem and DR. Christopher has a solution to put in the eye to remove it but the idea and concept scares me a little bit . I would like to see and hear the results of some people that have tried it . There are several factors though and I think that each case is different .
