Adapt to Every Light Condition with TONIC Photochromic Lenses

 

Built for light. Built for the water.

Tonic photochromic lenses adjust automatically, darkening in bright sun and lightening in low light, so you see well all day. They’re available in Copper or Grey.

Premium glass: Corning® Glass lenses for true colour, optical clarity and scratch resistance.

SliceLens™ technology: the world’s thinnest glass lens, only 1.7mm, for lighter all-day comfort.

VistaView™ lens design: distortion-free, edge-to-edge clarity.

ARC anti-reflective coating: less glare, less eye strain and more focus.

See better. Fish better.
