Getting your eyes examined regularly may help you detect a range of diseases very early in their development. Meghan Berkenstock, an ophthalmologist at Johns Hopkins, says it all has to do with blood supply to the eye.

Berkenstock:  We’re the only place in the body where you can see an artery. The arteries in the eye can really give you a window on to what's going on elsewhere. In our most common disease that we see is diabetes usually takes seven years after the sugars start to become elevated for the eye to become involved. Sometimes people the first symptom will be blurry vision they'll come in and they'll keep changing their glasses and they’ll say I still can't see or they'll start to have dry eyes this can easily be the first signs of diabetes we monitor them on a yearly basis or more frequently depending on the severity of the eye is involved and how much.   :31
