Two magnetic interchangeable lenses to keep you covered in any light.

Switch uses high-energy magnets embedded in the lens
and frame to easily swap lenses quickly as light conditions and activities change.
Switch lenses will literally jump into place when brought
close to the frame, but 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. When skiing, snowboarding,
running or mountain biking these lenses are designed to stay in place.
