blood sugar

Inspired by what I read in "Diabetes Solution" by Bernstein and other sources I decided to test this for myself. I was struck how similar the effects of diabetes to one's eyes were to those observed in glaucomatic eyes (diabetes causes glaucoma too BTW). Bernstein himself states that when his blood glocose was not under control he "suffered night blindness, balooning of the blood vessels in the eyes, macular edema and early cataracts".
