Why does diabetes increase risk of cataracts?
How can diabetes contribute to cataracts? The lens of the eye gets oxygen and glucose from the aqueous humor, which is the fluid that fills the front of the eye. If someone doesn’t have control over their glucose levels – such as someone with diabetes – the sugar levels can rise, causing the lens to swell.
