Momentum Photochromic Sunglasses

What Our Gearhead® Experts Are Saying:

"Halfway through a gravel century, clouds rolled in, and the light dropped fast enough that my dark lens turned useless. I popped it out and clicked in the clear one through the AutoLock hinges without pulling over or fumbling for a case. That fifteen-second swap is the difference between finishing strong and finishing squinting."

The 7x4 toric-shield curvature on the Momentum Photochromic Sunglasses from Smith Optics holds a consistent lens shape across the entire field of view, so the picture stays sharp at the edges whether you're locked into an aero tuck or sitting up through a rest stop. ChromaPop lens technology filters out the wavelengths that muddy contrast and color, which matters in the half-second it takes to read a wheel in a fast-moving group or pick a line through loose gravel.

The half-frame build is compatible with our optical docking system for riders who need corrective lenses, so a single frame covers race day and easy days without a separate prescription pair. The Evolve bio-based frame material keeps the whole setup light enough to forget about across a five-hour ride, and the design still holds enough structure to keep the toric lens properly seated mile after mile.

This is the pair for riders logging long mixed-light days, group rides that start at dawn and finish in full sun, and gravel routes where the terrain and the sky both keep changing.
