Removing the lower frame from a shield-style lens does more than save a few grams. The semi-rimless construction of the Sutro Lite opens up your downward field of view, letting you glance at a computer, check your line through a corner, or spot road debris without a frame edge cutting across your sightline. Oakley developed this design with urban cyclists in mind, but the expanded visibility works just as well on gravel descents or trail runs where you need to read terrain quickly.

The O Matter frame uses nylon-reinforced plastic that flexes on impact rather than cracking. At around 32 grams, the Sutro Lite sits light enough that you stop noticing it after the first few minutes of a ride. The temples extend straight back with a slight spring tension, and Oakley added Unobtainium rubber to their inner surface—the same hydrophilic material used on the nosepads. This compound actually increases grip as you sweat, which means the glasses stay put during hard efforts when lesser frames start sliding down your nose.

The cylindrical Plutonite lens provides distortion-free optics across the entire shield, including at the edges where spherical lenses can introduce some visual warping. Impact resistance meets Oakley's testing standards for high-mass and high-velocity contact, and the lens blocks 100% of UVA, UVB, and UVC rays plus harmful blue light up to 400nm. Depending on which lens tint you choose, you get Prizm technology tuned for specific light conditions—road versions enhance pavement texture and painted lines, while trail versions pull out contrast in mixed light under tree cover....
