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.

When Do Age-Related Vision Changes Occur?

Presbyopia. After you pass the milestone age of 40, you'll notice it's more difficult to focus on objects up close because of presbyopia. This is a perfectly normal loss of focusing ability due to hardening of the lens inside your eye.
