High blood sugar can result in severe damage in your eyes. In Canada, diabetes is one of the leading causes of blindness in adults. Since it is a painless disease, this is why you need to see your eye doctor for yearly screening.
It is estimated that 45 million people worldwide have glaucoma, and over 8 million are blind from it. Glaucoma is the second leading cause of blindness in people over 60, although it can affect younger people too. I call glaucoma the silent blinder as people don’t even realize they have it until late in the process, where permanent damage is done.
