Health.com: Could You Have Type 2? 10 Diabetes Symptoms

Blurry Vision

Having distorted vision and seeing floaters or occasional flashes of light are a direct result of high blood sugar levels.

"Blurry vision is a refraction problem. When the glucose in the blood is high, it changes the shape of the lens and the eye," Dr. Collazo-Clavell explains.

The good news is that this symptom is reversible once blood sugar levels are returned to normal or near normal. But let your blood sugar go unchecked for long periods and the glucose will cause permanent damage, possibly even blindness. And that's not reversible.
