Metformin can reduce the risk of high blood pressure affecting vision, and some researchers have discovered that the medication can also reduce the development of age-related macular degeneration (AMD), which is the leading cause of vision loss among people over the age of 50.
People with Type 1 and Type 2 diabetes do have a heightened risk for eye complications and blindness. Sight loss with diabetes, however, is not inevitable.
You can't see it—until it's too late. Diabetic retinopathy, the most common form of diabetic eye disease, is the leading cause of blindness in adults age 20–74. It occurs when diabetes damages blood vessels in the retina.

Although many people with diabetes develop impaired vision, fewer than 5% suffer severe vision loss.
Life expectancy for those with PN
According to 2019 research, diabetes and PN can lead to disabling nerve pain and lower limb amputation. The authors state that amputation in those with diabetes has associations with a low life expectancy, averaging 2 years.
