I have the diabetic problem and in fact through my eyes I found out I was a diabetic 2--- my problem is weird I guess to the real world in that what I am typing right now is hard for me to see because it's light print on a white background. I can see anything any one wants to show me-- but I cannot read the eye chart past 20/50 in my right eye and the top letter E with my left eye. It's amazing to me that I can see perfectly fine, just can't read light colored letters w/o a fount of about 12. Yet each time I go in for a check up I have to have a 20/50 in order to drive and every time I took the drivers test the testers told me that the doctors must be ill because I can read the speed limit signs and most signs just not as far back as most people. Why is it that eye tests only depent on reading letters or numbers? Seems rather silly to me-- because I have no problems with driving and see perfectly well-- no cloudy vision just low vision for light colored letters on an eye chart.
