Diabetes is a treacherous disease. It harms many things including one of your most valuable senses – the sense of sight. There are ways, however, that you can follow to protect and prevent damage to your vision. Doctor Elizabeth Seaquist, an endocrinologist at the University of Minnesota said that the key to preserving eye health lies in keeping the blood sugar and blood pressure at a normal level. She further added that it is critically important for diabetics to have better control of their sugar intake if they want to reduce the risk of eye problems.
