Like all of Uvex's sunglasses, the Sportstyle 114 Interchangeable Sunglasses have a sporty, innovative design specific to cycling. Unlike all of Uvex's sunglasses, these Sportstyle sunglasses won't add to that loan you took out for your bike's frame. An interchangeable lens system lets you switch out lenses quickly so you can ride with the correct tint in any condition. Select lenses on the Sportstyle 114 Sunglasses feature Uvex's Litemirror treatment for infrared ray protection as well as a mirrored style. Every lens is made from polycarbonate, though, and offers durable scratch resistance and 100% UV protection. A ten base curvature gives the lens a wider panorama, more coverage, and a better wraparound fit, while the soft nose and temple pads adjust to make that fit comfortable and precise.
