Age-related macular degeneration (AMD) is an age-related eye condition that affects central vision. This occurs as aging disrupts the functioning of macula - an essential part of the eye responsible for clear, focused vision. Macula is a component of retina, i.e., the light-sensitive lining at the back of your eyes. AMD is an unfortunately all-too-familiar issue, a major source of vision loss for seniors. It doesn't result in total blindness, but it can diminish your central vision and rob you of the ability to recognize faces, read, drive or do any close work like cooking or repair work.
