Unlike outdoor sunglasses, the lenses are a light density (darkness level), but will still ease the starkness of the glare to enable vision of other important items in or around the road. These glasses should not be worn in the daylight, or outdoors in the brightness of the sun.
Experience the pleasure of driving at night without the discomfort of bright, glary, and annoying headlights, that irritate your eyes, causes tension, and stress in your person. You will be pleased at the difference you will notice.
