HT, if you are serious about going blind, it might pay to have your sugar checked. I got a bad report in January, went on a diet, had my eyes checked, and 9 months later I am 4 sizes smaller, but my eyes check out as good as they have since second grade when the glasses became a permanent fixture, and my ACI was in the "clear " range last check up. I go back in about 3 weeks for the second round. Type II is insidious and goes after the eyes, the feet, and other body parts in subtle ways, doing its damage before being discovered unless you are vigilant. I could walk you around and tie your flies on for you, but I'm not sure I could tell you when the line moves fast enough for you to set the hook!
