Every single part of the human body goes through the process of aging, and each part responds in a different way to this process. When we speak about human eyes, there are many vision problems you may experience as you grow older. But before we discuss the age-related vision problems, let us discuss how age affects the eyes.
Effect of Aging on Eyes
Reduced Pupil Size
With age, the eye muscles lose their strength to control the pupil size and its reaction to light. This makes the pupil smaller and ultimately affects your vision clarity.
Tears keep the eyes moist. As you age, the production of tears decreases making your eyes dry. As a result, you might also experience burning sensation, stinging, and discomfort in your eyes.
Reduced Peripheral Vision
Visual field decreases by one to three degrees per decade of your life. So, as you age and reach 70’s or 80’s, you may lose 20 to 30 degrees of peripheral vision.
Decreased Color Vision
The cells that provide normal color vision decline due to sensitivity as we age. This affects the brightness of color you see and also makes it difficult to differentiate between colors.
Vitreous is a gel-like substance that liquifies and pulls away from the retina as you age. This can causes spots and floaters in your vision. You may even experience flashes of light.
Common Vision Problems with Aging
With age, the eye lens begins to get thick. This weakens your focusing ability, and the vision gets affected. This vision loss due to lens thickening is called presbyopia. At the start, your eyes may adjust to this vision loss, but later you will need glasses to correct your vision. Also, with increasing age, the eye power also keeps on increasing.
The lens is responsible for projecting images on the back of the retina and also to adjust the focus. This lens is made of proteins and water. As you age, protein in your eyes starts to clump up giving you a cloudy vision. This is known as cataract.
The macula is located at the back of your eye and contains millions of light-sensing cells. It is responsible for giving you clear vision. As you age, this macula starts to break down. There are different stages of AMD which can be diagnosed only with a comprehensive eye exam.
Glaucoma occurs due to a damaged optic nerve. If not treated, it can lead to vision loss and blindness. Hereditary and age are the most common reasons for this problem. Moreover, the symptoms of glaucoma cannot be noticed at an early stage.
Other than these eye problems, aging may also cause temporal arteritis, diabetic eye diseases, pterygiums, and many other problems. For any eye related problem at any age, visiting an optical clinic will provide you with the best solution.
