The most common symptom of astigmatism is blurred or double vision. If you are only slightly affected, you may not notice anything wrong. More significant astigmatism may cause noticeable distortions of your vision.
It is particularly important to remember that children with vision problems may not realize their vision is blurred. After all, they may never have seen the world in focus. That’s why it’s a good idea for children to have regular vision checks.
Here are some symptoms of astigmatism...
Other UV-related eye problems are pterygium and pingueculum. A pterygium occurs when the conjunctiva, the tissue that lays over the white of the eye, grows into the cornea. A pingueculum is a yellowish bump of tissue on the white of the eye.
Sunlight that bounces off highly reflective surfaces such as snow, water, sand, or pavement can be especially dangerous.
Photokeratitis is a corneal sunburn that’s also known as snow blindness. As the name suggests, skiers and snowboarders are particularly vulnerable to this temporary but acutely painful condition. “In photokeratitis, tiny blisters form on the surface of the cornea,” says Gail Royal, MD, an ophthalmologist in Myrtle Beach, S.C. “It’s a condition that will generally resolve on its own with proper medical treatment, but it’s uncomfortable enough to spoil your vacation.”
Sunglasses play a vital role in shielding the fragile tissue around the eye, says W. Lee Ball Jr., OD, an optometrist at Harvard Medical School’s Beth Israel Deaconess Medical Center. “This skin, including the eyelid itself, is very thin and vulnerable to skin cancer, and that’s especially troubling since dermatologists are reporting an epidemic in all types of skin cancer," Ball says.
Royal, who includes a review of proper sunglass use during patient visits, admits she sometimes appeals to her patients’ vanity.
“I’ll point out that sunglasses will protect not just against basal cell and squamous cell carcinomas and melanoma,” she says, “but also against the formation of wrinkles like crow’s feet and the unsightly thickening of the skin that can sometimes be caused by UV exposure.”
