7 Things You Need to Know Before Buying Sunglasses This Summer

Let’s face it: You’re neither a hermit nor a vampire, so when you leave your home, you’re walking straight into UV radiation.


Protecting your skin from sun damage is a no-brainer. But “your eyes can definitely get sun damaged as well,” says Dr. Brian S. Boxer Wachler of the Boxer Wachler Vision Institute inBeverly Hills.


Choosing sunglasses – the right sunglasses – is about much more than just about looking cool on a hot day. “People should think sunglasses are like sunscreen for your eyes,” Boxer Wachler said. Here are some buying tips:

 

Read the label.


“UV ultraviolet radiation is what causes most eye problems... we see it in people when they have really not been diligent about wearing sunglasses,” Boxer Wachler said. He added that eye sun damage can cause a variety of problems, including cataracts, cancers and even causing the whites of people’s eyes to become chronically bloodshot. TheAmericanAcademyof Ophthalmology recommends buying sunglasses labeled UV400 or 100% UV protection.


Dodge the glare.


“Polarized sunglasses cut down glare from other surfaces,” Boxer Wachler said. This is equally important if you’re into surfing, boating, fishing, snowboarding, skiing, or just driving on a sunny day. Make sure the label says “polarized” before you buy.

 

Catch more UVs.


“Wrap-arounds are preferable to sunglasses that just go straight across and leave a big opening on the sides where a lot of sun sneaks in around the frame,” says Boxer Wachler. Not your style? Try (currently trending) oversize glasses.


Shatter-proof


“Sports protection for eyes is very important,” Boxer Wachler said. “You can experience trauma to the eye by an elbow or hand... from a minor irritation, to getting poked, to a cornea abrasion, to optic nerve damage... where you can go blind in the eye.” Impact-resistant materials including polycarbonate and Trivex can protect eyes from fast-moving objects in general.


Price isn’t everything.


“We found no correlation with UV protection and price,” Boxer Wachler said. Just remember Rule No.1: Choose glasses offering UV400 or 100% UV Protection.


When you’re driving…


Remember the photo that went viral a few years ago, after publication in the New England Journal of Medicine, of a career truck driver with striking sun damage on the left side of his face? That effect, from driving into the sun’s harmful rays all day, is more common than you might think. “I see more left-sided cancer and cataracts in patients as well,” Boxer Wachler said, adding that his research found that front car windshields generally had decent UV protection but that side windows blocked only 71% of rays. He recommends a clear, UV protection window tint for side windows in addition to wearing wrap-around sunglasses while driving.


Got color?


Tinted glasses are not necessarily related to UV protection, but choosing glasses with a tint can help those who need clarity, especially in low-light conditions. “I know people who do target or competitive shooting at gun ranges,” Boxer Wachler says. “They use yellow and orange sunglasses because it can improve contrast.”
