By the end of day in the evening I get tired and my vision get very blurred and when I wake up in the morning I have a headache. I am 64 yeay old and have retired. I have had diabetes for about 10 years. Am on metformin 2000 ml slow release at night. 6 months check 8.6, 3 months 7.9 and recently 7.3 going the right way. What could be wrong?
Blurred vision is a very common (side effect) of high blood sugar
And while your numbers are going in the right direction, they are still high enough to cause the eye problems
If you can get down below 7.0 that should improve things and if you can manage down to 6.5 the blurriness should go away completely (at least on a regular basis) unless you have done some permanent damage to the small blood vessels in your eyes
Diabetes is the leading cause of blindness (Diabetic Retinopathy and Macular Edema) in persons under age 65 which should give most of us that extra kick in the butt to control our blood sugar better and also the reason that all diabetics should have an annual eye exam with an eye doctor and not just an optometrist, to look for early signs
If you see your eye doctor they can check you for cataracts just in case that’s causing your vision to be blurry. I have them in both eyes but not yet bad enough for surgery. I often get a headache from higher sugar’s
