Whether you’re a long-distance runner, traveling salesperson or bird watcher, the most important reason to wear sunglasses is to protect your eyes against ultraviolet radiation.
The potential dangers of UV-A are not as well documented, experts believe sunglasses should protect against at least 98 percent of UV-A and UV-B radiation.
In addition to percentage of UV protection, consumers should also consider optical quality, frame construction, proper color vision characteristics and other options such as polarization and mirror coating.
“You can find a pair of sunglasses on the rack that costs $15 or $20 and meets the UV protection and construction standards and you can buy a pair for $150 that’s locked behind some case that doesn’t meet any standards,” said Dr. Pitts. “Price just isn’t a good way determine the quality of sunglasses.”
