How Aging Affects Eye Structures and Vision

Just as your physical strength decreases as you age particularly as you reach your 65 and beyond, your eyes too exhibit an age-related decline in performance. There are a number of age-related eye changes that are perfectly normal. For instance, presbyopia is a normal age-related eye change and it is not a sign of any sort of some disease process. However, some age-related eye changes are not normal. Good news is, most of these conditions can be corrected. For instance, cataracts, which experts considered to be normal, can be corrected with cataract surgery. In this post, we have discussed some of the most common ways in which aging can affect your eye structures and vision.

  1. Reduced pupil size

When you reach 65 and above, the muscles that control your pupil size and reaction to the light naturally start to lose some strength. With time, this causes your pupil to become smaller. It also causes your pupil to be less responsive to the changes in ambient lighting. Dues to these changes, and elderly individual who is 65 or older needs three times more ambient light than those in their 20s to be able to  read comfortably. Also, people who are 65 and older are more likely to be temporarily deprived of sight by glare and bright light when coming from dimly lit buildings such as a movie theater. Seniors can use eyeglasses with anti-reflective coating or photochromic lenses to reduce this problem.

  1. Vitreous detachment

As you grow older, the gel-like vitreous inside your eye starts to liquefy and begins to pull away from the retina. This causes spots and floaters, and even splashes of light sometimes. This condition is known as vitreous detachment, and it is typically harmless. However, floaters and flashes of light can sometimes be clear signs of the beginning of a detached retina, which is a serious problem that sometimes causes blindness if left untreated immediately.  If you are 65 or older and you start to experience flashes and floaters, you should see your eye doctor as soon as possible to determine what could be the cause of the problem.

  1. Decreased color vision

As you age, the cells in the retina that are usually responsible for normal color vision start to decline in sensitivity. This causes colors to become less bright than they actually are. This condition also causes the contrast between different colors to become less noticeable. You should eat fresh, colorful fruits and stay hydrated to prevent this problem.
