Cyclists, a good pair of motorcycle sunglasses will ensure you get the most visual enjoyment. If it's an adrenaline-pumping mountain ride, you'll notice a clear difference between regular sunglasses and cycling glasses when you're sweating. Your body's heat will atomize an ordinary pair of sunglasses and your sweat will cause ordinary sunglasses to slide and even fall off. But the rubber non-slip nose rest of the riding glasses ensures that your glasses stay firmly on your face and don't slip even during more strenuous activity. These days, a growing number of high-end cycling glasses add vents between the lenses and frames to make them cooler and more comfortable to use without atomizing.
