C. T,
I would use the approach of the following:
A major contibutor to eye challnges is the typical high fat,high sugar, preservative-laden American diet. Since the deficiency of just one vitamin or mineral can lead to a variety of eye challneges. Lutein, Glucosamine, Bilberry, Blueberry, Vitamin C, Vitamin E, and Grape Seed are all good sources of natural ingredients that help with the deficiencies. What is in our food and household products actually hurt us in many cases of diseases, conditions and even fatalities. It is all over the news right now, Olivia Newton John has an awesome take in USA Today on Chemicals in the home and our food. Might help you out.
