Driving sunglasses are a pair of glasses featuring tinted lenses, designed to make driving safer and more comfortable in bright conditions. They tend to have large lenses and thin frames, for good all-round visibility. Driving sunglasses are also likely to feature polarized lenses, which reduce glare from the road, headlights, and reflective or white surfaces. Driving sunglasses should also protect their wearer against UV radiation, by filtering it out before it can reach the eyes. Driving sunglasses are available in a wide variety of styles, and with different lens tints. Gray and brown tints are generally preferred when manufacturers develop sunglasses with driving in mind.
