3. Consider extra features
High-end frames won’t offer any more protection than a cheap pair that blocks 100 percent of UV rays, but they may have extras that make your eyes more comfortable when in the sun—and thus make you more prone to wearing them, according to Dr. Monica. Polarized lenses, for example, help reduce glare. Just make sure they’ve also been treated with UV protection, as some shades are just polarized. Blue-blocking glasses, which typically have yellow or orange lenses, make distant objects easier to see and sharpen the contrast in colors, so they’re great for seeing in fog and haze.
