	2	3	Diabetes Type II	High blood sugar can cause two problems which affect vision, namely blurred vision and retinopathy - a disease of the back of the eye. Blurred vision is one of the first signs of elevated blood sugar. The shape and size of the lens in your eye changes when your blood sugar fluctuates. This swelling of the lens can cause blurred vision. If you notice blurred vision, you should have your blood sugar checked. The acceptable range for fasting glucose is 80-110mg. If your blood sugar is substantially higher or lower than the acceptable range, contact your doctor. When your blood sugar is controlled, your vision will return to its previous state.
