Photochromic lenses solve a persistent problem for cyclists and runners who train through variable conditions: carrying multiple pairs of glasses or squinting through the wrong tint. Oakley's Cybr Dyno with Clear to Black Iridium Photochromic lenses eliminates that compromise entirely, transitioning automatically from fully clear indoors to a dark tint in bright sunlight. The lenses react to UV exposure rather than visible light, which means they darken even on overcast days when glare can still cause eye strain. When the light fades, they return to clear without the lag that plagued earlier photochromic technologies.

The Cybr Dyno continues Oakley's rimless sport lineage with a toric shield design that wraps around your field of view. Plutonite lens material handles the structural duties that a frame would normally provide, keeping overall weight down to just 22 grams while meeting Oakley's impact-resistance standards for high-mass and high-velocity protection. The rimless construction opens up peripheral vision and reduces the frame bulk that can interfere with helmet straps or create pressure points during long efforts. A 6-base wrap and 15-degree pantoscopic tilt position the lens to follow facial contours and maintain consistent optical clarity across your sightline.

Retention comes from Oakley's grip materials rather than tight spring tension. The O Matter temples integrate Unobtainium earsocks that actually increase grip as you sweat, countering the usual tendency for glasses to slide during hard efforts. Ligature nosepads provide adjustable contact without the bulk of traditional adjustable nose pieces. Ventilation ports cut into the lens reduce fogging when you're working hard or transitioning between temperatures. The matte white frame keeps aesthetics clean without the fingerprint visibility of polished finishes.... Read More
