The Oakley Enigma Mass 8191 eyeglasses combine athletic engineering with everyday wearability. This full-rim square frame features a mixed-material construction that balances durability with lightweight comfort.
The front frame is constructed from O Matter, Oakley’s proprietary stress-resistant nylon that’s 25% lighter than acetate and twice as strong. It flexes under pressure instead of snapping, resists temperature extremes, and delivers all-day comfort without the weight. The temples are made from lightweight C-5 alloy—a five-metal blend that tapers from thick to thin, paying homage to Oakley’s signature trigger stem design from their sport sunglasses heritage.
Unobtainium nosepads and earsocks provide the no-slip grip Oakley is known for. This hydrophilic rubber actually increases traction when you sweat, keeping the frames locked in place during movement. It’s the same material trusted by athletes, now engineered into a lifestyle frame.
These frames are fully prescription-ready and compatible with single vision, progressive, and bifocal lenses. Add blue light filtering for screen time, photochromic lenses that adapt to changing light, or anti-reflective coatings for sharper vision. The square shape and generous lens height make them well-suited for progressive prescriptions, giving optical labs the vertical space they need.
The Enigma Mass features a bold square shape with mixed-material construction that pairs the matte texture of O Matter with the metallic finish of C-5 alloy temples. Distinctive Oakley icons mark the temple tips.
Available in two sizes—55mm and 57mm lens width—to fit a range of face shapes. The unisex design works for anyone seeking sport-inspired eyewear with real substance behind the style.
