Latest Eyesight News
SUNDAY, Dec. 15, 2019 (HealthDay News) -- With the arrival of winter, it's time for skiing, sledding and ice skating, but it's also when snow blindness can strike.
Snow blindness is like a sunburn in the eyes. It's caused by the same UV rays that give you that summer tan. In the case of snow blindness, the rays are reflected off the snow and into your eyes, explained experts from Ohio State University's Wexner Medical Center.
UV burns to the cornea are called photokeratitis. Inflammation of the epithelial layer can result in blurred vision. When this happens after being outside on a bright snowy day, it is commonly referred to as snow blindness.
Photokeratitis can also occur at high elevations where less UV light is absorbed by the atmosphere, the experts noted in a medical center news release.
The label should read: "Blocks 100% UV-A and UV-B," or "UV400."
If you think you have snow blindness, first get out of the sun. Next, see an eye doctor, the team advised.
Photokeratitis usually goes away by itself in a couple of days. Until it does, stay out of the sun. Also, don't wear contact lens, they added.
Common treatments include artificial tears, cool compresses and over-the-counter painkillers. In addition, don't use a tanning bed without protective goggles and always wear eye protection when welding.
