Top 5 eye conditions from sun damage
Laying out at the pool, building sandcastles on the beach, tossing a flying disc at the park — these are typical “fun in the sun” activities. But with all that fun you’re having, are you blinded to the dangers of sun exposure?
Learn about the top 5 eye problems that can result from sun damage — and your options for treatment.
5 eye problems caused by sun exposure
Ultraviolet (UV) exposure is responsible for 80% of visible signs of ageing. UV rays are harmful to your skin, and they age you a bit more each day by creating new wrinkles, sun spots and looseness in the skin around your eyes.
In addition, squinting due to the sun can cause crow’s feet and deepen wrinkles. Wearing protective sunglasses designed to block UV rays helps to minimize further damage to the skin around the eyes and all ocular structures.
Consumers should look for ultraviolet (UV) lens protection that is UV400 or higher. This rating means that 99.9% of harmful UV rays are blocked by the lens.
UV sunwear will prevent sun damage to the delicate skin around the eye and decrease the likelihood of the occurrence of skin cancer.
2. Corneal sunburn
The cornea is the clear outer covering of the eye and can be considered the “skin” of your eye. Just like skin can be sunburned, so can the cornea. A sunburn of the cornea is called photokeratitis. This is a painful inflammation of the cornea caused by unfiltered UV ray exposure.
As with most sun-related eye problems, the solutions involve use of proper UV protective sunwear.
Did you know that unfiltered UV exposure can cause or accelerate cataract development?
A cataract is a clouding of the lens in the eye that can affect vision. While this eye sight problem is most commonly associated with ageing, you can reduce your risk of developing cataracts by wearing proper UV-blocking sunglasses.
4. Pinguecula and pterygia
Pinguecula and pterygia are growths on your sclera (the white of your eye) due to excessive sun exposure.
A pterygium has the potential to spread onto the cornea and negatively impact vision while a pinguecula does not.
Wearing proper UV protection is the best preventative treatment for development of these topical growths.
If the pterygium affects vision, surgical removal may be considered. If either growth causes irritation, a topical lubricant is often prescribed.
5. Macular degeneration
The impact of ultraviolet radiation on the development of macular degeneration is not fully understood.
Macular degeneration involves the disruption of the macula, the central area of the retina, which is responsible for clear vision. Some studies suspect that age-related macular degeneration can be exacerbated by sun exposure.
Comprehensive eye examinations and protective sunwear can prevent the progression of this condition.
Is it possible to reverse sun damage?
Nearly all of these sun-related eye problems and symptoms can be treated in some way, alleviating the side effects if not reversing the process altogether.
It’s best to protect yourself from the sun and prevent the damage before it can start. This includes protecting kids from sun exposure as well. UV rays can lead to eye problems in children also, and long-term sun exposure from childhood can lead to eye problems later.
The best way you can do that is to wear sunscreen with water-resistant, broad-spectrum coverage and an SPF of 30 or higher, UV-blocking sunglasses and a wide-brimmed hat each time you go outside.
