Are you having problems seeing right?
If you are having constant unexplained problems with your vision, you might want to go to an Optrimist. But if your mainly having blurred vision you should check out other symptoms of diabetes to see if there are any present.
The reason why you get blurred vision (in diabetes) is because of high levels of blood sugar pull fluid out of the tissues in your body, including the lenses of your eyes. This affects your ability to focus greatly. But when you get your diabetes treated, and your blood sugar levels drop, your vision starts to return to normal. Over a long period of time, diabetes can damage old blood vessels in your eyes and this could eventually lead to more serious complications such as blindness.
