Diabetes can affect your eyes in a number of ways. For example, if your blood sugar levels are high, this can affect the lens inside your eye causing blurring of your vision, and it can also cause your prescription to change in a very short space of time. Diabetes can also cause a condition where the delicate blood vessels on the back of the eye can leak, or become blocked. For this reason it is very important that all diabetics have their eyes examined at least annually. If the optometrist does notice some leakage at the back of the eye, they may think it appropriate to refer you to see an ophthalmologist (an eye specialist who works in a hospital), who may decide to treat the leakage with a laser if they feel that it may affect your vision. If your sugar levels are well controlled, this will significantly reduce the likelihood of you suffering from this condition.
