The increasing popularity of activities like mountain biking, snowboarding, rock climbing, kayaking, skiing, and windsurfing has created an industry for glasses & sunglasses that have been specifically designed to optimize athletic performance. They are exceptionally light, comfortable and able to withstand extreme conditions, all while staying in place and providing sharp and glare-free vision.
Sports & Performance Lenses
A key aspect of effective sports eyewear is optical quality and visual enhancement. Sports and performance lenses are available in a wide variety of tints to modify light and enhance contrast. This allows you to see certain objects (a tennis ball, for example) with greater clarity to shorten reaction time.
Polycarbonate lenses are the lens of choice for most sport sunglasses because they are lightweight and extremely impact-resistant.
Polarized lenses decrease glare by blocking incoming light that has been reflected from flat surfaces like water or snow. There is, however, some debate about the advisability of polarized lenses for sports like mogul skiing, since seeing reflected sunlight may help to visualize contours & icy patches.
Sports & performance frames are made from lightweight and durable materials such as polyamide, which maintains its shape under stress. Styles are aerodynamic with sleek lines, and the no-slip temple grips and nose pads help keep eyewear in place despite perspiration.
