What is a common symptom associated with diabetes that can affect eyesight?

Diabetic retinopathy is a significant and common symptom associated with diabetes that directly affects eyesight. It's a condition that arises due to damage to the blood vessels in the retina caused by prolonged high blood sugar levels. Individuals with diabetes can experience changes in their vision due to the leaking of fluids or the formation of new, abnormal blood vessels in the eye, leading to potential vision loss if not managed properly. The progression of diabetic retinopathy can often be asymptomatic in its early stages, which is why regular eye examinations are crucial for early detection and treatment.

By managing blood sugar levels effectively, patients can reduce the risk of developing this condition, making awareness and regular screenings vital components of diabetes management.
