When the sun hits the White Cliffs of Dover, your namesake Smith ChromaPop Photochromic Dover Sunglassses will automatically darken so you're not blinded by the light. These lightweight shades adapt to the light at any given moment, so in bright light or hazy glare you'll be able to see colors and shapes clearly. ChromaPop photochromic lenses are treated with anti reflective and hydroleophobic coatings to minimize backlight glare and repel moisture and grime. Wear the Dover shades when traveling through Beijing to reach ancient temples, and at least your shades won't be coated in a thick of layer of city smog. The wide base offers more eye protecting coverage, reducing the degree to which UV rays are able to sneak in through the bottom. Megol nose and temple pads get grippier as you get sweaty, so whether you're taking in the Chicago skyline mid August or standing in surf spray, the water won't cause you to lose your shades.
