I have read that medical personell trained in spotting plaque in the vascular system can spot plaque in the eyes of CVD patients. Some heart & CVD research indicates that CVD can also effect eye sight.
I use "Natures Way" over 50+ high potency daily multi-vitamin. Break them in half, one-half in the morning, one half before bed. Also supplement with minimum 2 grams plus (2000+ mg) Vitamin C @ 500 mg doses throughout the day (max vit c absorbtion 500 mg per hour), 5000iu D3... So far seems to be an effective strategy. YMMV
