Semi-rimless construction changes how a shield lens sits on your face. By removing the lower frame entirely, the Oakley Sutro Lite Sweep drops weight and opens up downward sightlines that matter when you're looking at a bike computer or checking road surface in your peripheral vision. The lens curves upward at the outer edges in a sweep pattern that references Oakley's 1984 Eyeshade design, providing side coverage without the squared-off profile of the standard Sutro. This hybrid approach pulls the retro aesthetic forward while building on current Prizm lens technology and O Matter frame materials.

The Sutro Lite Sweep sits between the full-frame Sutro and the more minimal Sutro Lite in terms of coverage. At 139mm wide and 60mm tall, the lens provides substantial wind and debris protection while the swept edges taper toward the temples rather than extending straight back. That taper creates a more compact visual profile that works well with a wider range of helmet shapes and face sizes. The 138mm arms run slightly shorter than the standard Sutro, reducing interference with helmet retention systems and Mips liners that can push longer arms out of position.

O Matter frame material handles the structural work along the brow line, running roughly 25% lighter than standard acetate while maintaining the stiffness needed to hold the lens in optical alignment. Oakley claims the material runs twice as strong as acetate, which matters in a semi-rimless design where the frame takes more stress without a lower rim to distribute load. Ridged Unobtainium texture on the inside of the temples adds grip that increases as you sweat rather than becoming slippery. The same material shows up on the adjustable nosepiece, which includes multiple sizing options for dialing fit across different nose bridge shapes.... Read More
