Experience the difference

Match your RIG® lens to the conditions you play in.
Choose from a wide range of lens tints to suit all uses.

Visible Light Transmission (VLT) describes the percentage of light in the environment that reaches your eye after passing through the lens. A lower number corresponds to a darker lens. Generally speaking, a higher VLT lens will suit lower light conditions, and a lower VLT lens will suit brighter, sunnier conditions. 

RIG® Lens Technology

RIG® is a revolutionary lens technology developed by Sweet Protection to provide superior contrast-enhanced vision, minimise color distortion and reduce eye fatigue. RIG® controls which wavelengths of light are transmitted through the lens, enabling the eyes to see more detail and protecting them from harmful rays. By choosing to 'RIG® your experience', you are choosing game-changing vision that allows you to push your limits, no matter where you play.
