No, I’m not referring to interchangeable camera lenses, I’m talking about the lenses in your sunglasses. Switch Vision is a sports performance sunglass company with a patented interchange lens system that uses high-energy magnets embedded in the lens and frame to enable users to quickly swap lenses and easily as light conditions and activities change. There is a large variety of frame styles to choose from and lenses are available with or without a prescription. Specialty lenses are also available including readers for up-close map and GPS work. Prices range from $40 – $115 for one frame and set of lenses (non-prescription).
