Welcome to the Switch Vision online store. Switch magnets make changing lenses quick and easy, yet hold lenses in place securely. Switch uses high energy, rare earth magnets embedded in the lens and frame to enable users to swap lenses quickly and easily as light conditions and activities change. Switch lenses will literally jump into place when brought close to the frame and will stay put once the lenses have snapped into position. Switch magnetic interchange lenses have been engineered to stay in the frame when dropped from a height of six feet or subjected to the intense, repeated jarring of skiing, snowboarding, running or mountain biking.
