It changes the index: High blood sugar level is known to affect the crystalline lens through the effect on the sorbitol pathway, usually making the lens to be more swollen and thus more myopic. High sugar level can also affect the cornea thickness and changes the eye's overall refractive index though it is usually a less significant factor.

Retinopathy: Uncontrolled sugars can also lead to retinal swelling. See your ophthalmologist for a total ocular evaluation.
