Macular degeneration is a deterioration of the central portion of the retina that causes poor central vision and is the leading cause of impaired reading or detailed vision. In other words, the part of your eyes responsible for seeing directly ahead starts to get thinner. This is called the macula, and macular degeneration means that it’s beginning to wear out.
With fewer cells to receive light and colors, your brain has a harder time creating a clear picture. You can still see, just not with the same clarity as before. Although macular degeneration causes distortion of central and color vision, side vision is not affected. Your peripheral vision can stay just as sharp as ever.
