As to your uncle, the way to help with his eyesight is to maintain his blood sugar. The normal people will have 70-130 milligrams per deciliter or mg/dL. After having meal, the blood sugar will be less than 180 mg/dL one to two hours later. Your uncle should visit the eye doctor for regular exams. High blood sugar may increases the risk of eye problems.

While I think your uncle's vision problem is just a temporary problem that is caused by high blood sugar levels. I think he can solve this kind of eye problem. He can get his blood sugar back to the target range. Usually it will take three months for his vision to get back to the normal standard. So don't need to buy the glasses.

Diabetes causes problems in the retina with what are collectively called microvascular abnormalities. The small blood vessels develop microaneurysms and leak blood. New blood vessel growth occurs. Unfortunately, these blood vessels are weak and also leak. These leaks can cause irreversible damage to the retina and permanent vision loss.Patients with controlled diabetes do better than those with uncontrolled diabetes. However, even a person whose diabetes is under perfect control can still develop diabetic retinopathy, hence, the need for yearly retinal exams.
