Age related macular degeneration, commonly referred to as AMD, is an eye disease associated with aging that gradually diminishes sharp, central vision. Central vision is needed for seeing objects clearly and for routine daily tasks such as reading and driving. AMD affects the macula, the part of your eye that allows you to see fine detail.
In some cases, AMD advances so slowly that many people notice little change in their vision. In others, the disease progresses faster and may lead to vision loss in both eyes. AMD is a leading cause of vision loss in Americans 50 years of age and older
