Most importantly, diabetic blindness is usually preventable if diagnosis and treatment are begun early enough. Similarly, reducing blood pressure and cholesterol can be a big help. Watch your diet, follow your glucose levels and see your medical doctor regularly. You may take a blood test called Hemoblobin A1c, which reveals the average glucose over the preceding 3 months and is a better measure of overall control. Controlling blood sugar is the best way to stay healthy.
Good control can prevent many complications of diabetes.
In addition to tight control of your blood sugar, you should have your eyes examined regularly, at least once a year with dilated pupils , by a qualified ophthalmologist. An optical store where you purchase glasses may not provide an adeqate examination necessary for people with diabetes. Even before you notice a change in your vision, such an examination can detect problems that threaten your vision. Early detection and timely treatment is the best way to control diabetic eye disease. If you haven't had your eyes examined within the last year, your sight is at risk.
