As we age, many of us develop problems with our vision. Almost half the people over age 75 have cataracts, which cloud the lens of the eye and blur vision. Cataracts are the leading cause of impaired vision in the elderly. Age-related macular degeneration (AMD), in which a ‘blind spot’ develops in the center of vision, is the leading cause of blindness over age 55.
