Doctor's Orders: The Importance of Wearing Sunglasses
It's known that the sun's ultraviolet (UV) rays do damage to the skin. However, not everyone realizes the same UV rays will harm more than just the skin. That's why protection from the sun isn't limited to sunscreen only.
Sunglasses Are Protection Against Sunburn in the Eyes
Eyes can become sensitive to light after they're exposed to the sun. Additionally, the eyes may become swollen or bloodshot. However, the sun can cause more than just mild discomfort. In some cases, the eyes may become sunburned. When this happens, eyes become pink or red and swell. The eyes will hurt or feel tender. In some cases, the eyes will become itchy. More severe cases will cause fluid-filled blisters to form. These blisters may break. Severe cases of sunburn of the eyes may affect the person in other ways. For instance, the person can develop a headache or fever. Chills and fatigue are common as well.
Sunglasses Are Protection Against Cataracts
Cataracts are a progressive clouding of the lens of the eye. Cataracts are a common occurrence. In fact, more than 24.4 million Americans ages 40 and older have them. By the age of 75, over half of all Americans have cataracts, as noted by the American Academy of Ophthalmology. Age, heredity, and diabetes all play a role in the onset of cataracts; however, UV exposure can cause them as well.
Sunglasses Are Protection Against Macular Degeneration
Macular degeneration is a term used to describe damage to the macula, which is the nerve in the back of the eye. When your eyes are exposed to UV rays over time, you heighten your chances of developing macular degeneration. A family eye care doctor will examine the back of the eyes and review your medical history to determine if you have macular degeneration. Your Cookeville optometrist may conduct further testing if he or she suspects macular degeneration. For instance, an Amsler grid can help a Cookeville eye doctor tell if you have defects to the center of your vision.
Sunglasses Are Protection Against Cancer
Sunlight coming in contact with your eyelid, eye or skin surrounding the eye can cause cancer. Cancer of any one of these areas is possible. An optometrist in Cookeville may detect melanoma during a regular eye exam, but it may require further testing from an oncologist to determine if a person has cancer in or around the eye.
