I have noticed remarkable shifts in the ability of my eyes to focus for reading. When last I was eating a lot of bread and cheese, my eyesight deteriorated so badly that I had to use 1.0 specs to read anything. Since eating for my blood-type, I can now read newprint most days without specs. (small stuff I need to use a magnifying glass tho). I am convinced that diet can play a big part in the functioning of eyes! Lynton
