Age-related macular degeneration (AMD) is an eye disease that can blur your central vision. It occurs when aging causes damage to the macula the part of the eye that controls sharp, straight-ahead vision. The macula is part of the retina (the light-sensitive tissue at the back of the eye).AMD is a common condition — it’s a foremost reason of vision loss for older adults. AMD doesn’t cause complete loss of sight, but losing your central vision can make it tougher to see appearances, speak, drive, or do close-up work like cooking or fitting stuffs all over the house. AMD occurs gradually in some people and sooner in others. If you have initial AMD, you may not notice vision loss for a long time. That’s why  it’s necessary to get consistent eye exams to find out if you have AMD.
