The number one cause of blindness worldwide is type II diabetes, of which is usually caused by being overweight or obese & neglecting physical fitness. In fact, most diabetics show signs of the onset of blindness before 20 years have passed from initial diagnosis of diabetes. The worse the person’s blood sugar, the more they are at risk of blindness over time. High blood sugar causes small aneurysms to occur near the retina of the eye. If they burst, a minute amount of blood will filtrate into the retina and leave behind residue buildup that can cause blindness after repetitive occurrences.
Type II diabetes can also cause occlusions of the blood vessels in the retina, leading to scarring, glaucoma, and painful blindness.
Regular eye exams and treatments for diabetes can slow the onset of blindness, as caused by this disease. (8C)
