How does diabetes impact vision?

Diabetes significantly impacts vision in several ways, primarily through the development of specific eye conditions. Diabetic retinopathy is a common complication where high blood sugar levels damage the blood vessels in the retina, leading to vision loss if left untreated. Individuals with diabetes are also at an increased risk of developing cataracts, which cloud the lens of the eye and can cause blurry vision. Moreover, the risk of glaucoma, a condition that can damage the optic nerve and lead to blindness, is higher in people with diabetes. Thus, the correct answer highlights the various serious vision-related complications associated with diabetes, emphasizing the importance of regular eye examinations for those with the condition. The other options do not accurately reflect the effects of diabetes on vision and could mislead about the serious risks involved.
