You may want to see an opthamogist rather then trying Vitamins. Diabetes can cause eye-related problems. There are things (like Macular Edema, Uvietus (sp?) )to rule out as they can be age-related, vascular and/or diabetic and can affect night vision, color vision and detail vision. I suggest you see a doctor. Auto-immune stuff needs to be considered. They are looking at Diabetes suspecting it may be auto-immune - an interesting theory.
