Blurry Vision? It Could Be Your Blood Sugar
13 Dec
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.
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.
