At night or in cloudy weather, such glasses will be minimally darkened, which will allow you to clearly see your surroundings and protect your eyes from the glare of headlights. When it’s a bright sunny day, the chameleon glasses will be darkened as much as possible and will protect from ultraviolet radiation, your eyes won’t get too tired.
