Most people are not aware of the fact that high blood glucose levels is one of the most common reasons for vision loss among adults in the whole world. Diabetic patients have an increased risk of developing eye complications which, if left untreated, can lead to poor eyesight and blindness.

However, with frequent monitoring of blood glucose levels and with regular eye examinations and early treatment, it is possible to prevent 98% of serious vision loss due to diabetes.

How can diabetes affect the eyes?
High blood glucose levels can cause changes in the shape of the lens which can temporarily cause blurring of your vision. This commonly occurs before being diagnosed with diabetes or when diabetes is out of control. When blood glucose levels are reduced through appropriate treatment, the blurriness usually disappears. Therefore getting new glasses should be delayed until blood glucose levels are under better control.

The blood vessels of the retina may swell and leak fluid leading to changes in the retinal layers and causing visual blurriness. This condition is known as diabetic retinopathy and is commonly found among Type I and Type II diabetic patients.

Persistently high blood glucose levels can increase the risk of more serious eye problems in people with diabetes, including:

  • Retinopathy
  • Cataracts
  • Macular degeneration
  • Glaucoma
