Age-related macular degeneration (AMD) is one of the most common cause of severe loss of vision in people ages 50 and older. Central vision is affected with this disease.
AMD not only affects the central vision but also the ability to see fine details. In AMD, the macula is damaged. In advanced stages, people lose their ability to drive, to see faces, and to read smaller print. In its early stages, AMD may have no signs or symptoms, so people may not suspect they have it.
There are several risk factors that can contribute to developing age-related macular degeneration, including:
The symptoms of AMD depend on the stage. Dry AMD happens in 3 stages: early, intermediate, and late. AMD is a progressive disease — that means symptoms usually get worse over time.
Straight lines looking wavy is a warning sign for late AMD. If you notice this symptom, see your eye doctor right away.

These steps lower the risk of AMD:
Eat a healthy diet.
