It appears vitamin D levels may affect a person's risk for age-related macular degeneration or AMD.

AMD is the leading cause of vision loss in Americans 65 years and older. A new study shows women under 75 years old who got the most vitamin D had a 59 percent decreased risk of developing the condition.

Women who had high blood vitamin D levels also saw a decreased risk of AMD. Some of the top food sources for vitamin D are milk and fish.

Sunlight is also a source of vitamin D, but the study showed it had no effect on AMD risks.
