Bisphaera Speed Photochromic Sport Sunglasses

Oakley Bisphaera Speed Photochromic Sport Sunglasses

With a twin-lens design sharpened for aerodynamics, the Oakley Bisphaera Speed Photochromic Sunglasses deliver unmatched grip, coverage, and versatility, so you can focus on the effort, not your gear.

The lightweight O Matter™ frame is stress-resistant and built for endurance, offering all-day comfort that traditional materials can’t compete with. Paired with a semi-rimless construction, it sheds unnecessary weight while maintaining durability, ensuring nothing slows you down. Unobtainium® nosepads and earsocks lock the sunglasses in place, even during the most intense sprints or climbs, so you stay focused on the road ahead. Designed for athletes who refuse to compromise.

The photochromic lenses adapt quickly to changing light, darkening under bright sunlight and clearing as the skies soften. This seamless transition means your vision remains optimised whether you are sprinting through dappled woodland, stepping onto an exposed hillside, or moving from outdoor bright into indoor shadow.
