Symptoms of Diabetes Blurry Vision
Blurry Vision caused by Diabetes is a temporary problem caused by high blood glucose levels. High blood glucose causes the lens of the eye to swell, which changes your ability to see. Getting your blood glucose back to normal levels will often correct this kind of blurred vision. It may take as long as three months after your blood glucose is well controlled for your vision to fully return to normal.
Note that blurred vision can also be an indicator of other serious medical problems. Contact your physician for more information.
