Momentum Photochromic Sunglasses

What Our Gearhead® Experts Are Saying:

"I hit a switchback climb with my head tipped back further than I usually ride, and for the first time in years, there was no black bar cutting across my eyebrows. The toric lens curves up and over instead of stopping short, so my whole field of vision stayed open through the turn. That half-frame shape is the reason I stopped noticing I had sunglasses on at all."

A three-hour ride rarely holds the same light for long, and swapping lenses mid-climb ruins momentum most riders would rather keep. The Momentum Photochromic Sunglasses from Smith Optics handle that shift automatically, darkening as the sun breaks through tree cover and clearing again once you roll back into shade, so your eyes adjust without your hands ever leaving the bars. The two-position nose pads and corewire temples grip tighter the harder you push, which means the fit holds through the sprint at the end just like it did on the neutral roll out. This is the pair for riders who want one setup that works from sunrise starts through full afternoon sun.
