There are two types of diabetes—type 1 and type 2. Both types can have short-term and long-term effects on our eyes and our ability to see properly. The most serious effect resulting from diabetes is a condition called diabetic retinopathy (disease of the retina). Poor control of blood sugar levels can result in damage to the small retinal blood vessels that lie within the back inner lining of the eye. This leads to a lack of oxygen to the retina and can ultimately lead to loss of partial vision and even complete blindness. Less serious side effects of high blood sugar levels can cause a swelling of the lends inside the eye. This can cause a shift in a person’s prescription and some individuals may find that they can no longer see well with their glasses, or their vision is constantly changing. This change will usually return to normal as blood sugar levels stabilize.
The best prevention of diabetic retinal problems or constant changes in vision is early detection of any problems and strict control of blood sugar levels through medication and/or diet and exercise.
