Can Dr. Chitaranjan Mishra's advice help prevent diabetic retinopathy?

Yes, maintaining stable blood sugar levels through diet, exercise, and medical guidance, as advised by Dr. Mishra, is the best way to protect against diabetic retinopathy and preserve vision.

What causes blurry vision when blood sugar spikes?

When blood sugar increases, the lens in your eye absorbs sugar, drawing in fluids and swelling, which changes its shape and affects focus.

Why are regular eye exams important for diabetics?

Regular eye exams can detect early signs of diabetic retinopathy before vision loss occurs, allowing for timely treatment and management.

Summary

Blurry vision may indicate underlying blood sugar problems.
High blood sugar swells eye lenses, causing temporary blurriness.
Diabetic retinopathy from chronic high sugar can cause vision loss.

Blurry Vision? It Could Be Your Blood Sugar

An eye specialist warns that blurry vision, often dismissed as fatigue, can be a key indicator of blood sugar imbalances. Changes in blood sugar can significantly impact eye health, similar to their effects on other organs.

When blood sugar levels rise, the lens of the eye absorbs extra sugar, drawing in fluids and causing it to swell. This alters the lens's shape, leading to temporary difficulty focusing. While this blurriness usually subsides as sugar levels normalize, persistent fluctuations can create lasting focusing problems.

Prolonged high blood sugar, known as chronic hyperglycemia, poses a more severe risk by damaging the retina's delicate blood vessels. This can develop into diabetic retinopathy, a condition that may lead to irreversible vision loss if not promptly treated. Regular comprehensive eye exams are therefore essential, even for those with seemingly perfect vision, to detect early retinal changes.
