Just as our physical strength decreases with age, our eyes also exhibit an age-related decline in performance — particularly as we reach our 60s and beyond.
Some age-related eye changes, such as presbyopia, are perfectly normal and don't signify any sort of disease process. While cataracts can be considered an age-related disease, they are extremely common among seniors and can be readily corrected with cataract surgery.
Some of us, however, will experience more serious age-related eye diseases that have greater potential for affecting our quality of life as we grow older. These conditions include glaucoma, macular degeneration and diabetic retinopathy.
