DEAR DOCTOR K: I was recently diagnosed with Type 2 diabetes. Can you explain how diabetes affects vision?
DEAR READER: Both of the common types of diabetes, Type 1 (which usually begins in childhood) and Type 2 (which usually begins in adulthood), can affect vision in several ways. After 20 years of having Type 2 diabetes, most people have eye problems. But the risk can be reduced, as I'll explain.
