Kalsten | Smart Color-Changing Sunglasses, UV-Resistant Polarized Day and Night Goggles, for Driving, Surfing, Surfing, Skiing, Fishing and More
Enjoy the sunshine without feeling dazzling.
This photochromic lens can automatically sense the intensity of light changes, absorbing the ultraviolet rays.
The stronger the light is, the darker the color of the lens will be.
The sunglasses will effectively filter the strong light, strengthen the visual definition, reduce eye fatigue, and keep your eyes comfortable.
The second generation of sunglasses has flexible spring hinges that fit different shapes of faces.
The upgraded version uses a hydrophobic material, making fingerprints and water stains easily wiped clean.
In addition, the second generation of ground mirror legs also uses the plating process, high-temperature resistance, corrosion resistance, not easy to fade.
Perfect for cycling, running, fishing, driving, skiing and hiking.
