The Harrier Electrochromic Brightness-Changing Sunglasses are useful in all types of outdoor situations. Because they automatically adjust depending on your environment, you can wear them in very sunny or shadier spots. These are autonomous sunglasses that respond to the sun in just a tenth of a second. Depending on the light you encounter, their lenses will turn darker or lighter to respond to it. And, though these sunglasses can handle a lot on their own, you’re still able to touch control them. By doing this, you can quickly switch between modes for driving and playing outdoor sports. Additionally, these responsive sunglasses can help improve your visibility in foggy circumstances. As a result, these autonomous sunglasses can help you drive safer.
