The Oakley Chamfer Squared 8143 eyeglasses bring performance-driven engineering to everyday prescription frames. Built around a clean square lens shape with subtly beveled temples, this frame balances modern style and Oakley’s decades of materials innovation.
O-Matter Frame: Lightweight and Built to Last
The Chamfer Squared is constructed from O-Matter, Oakley’s proprietary thermoplastic nylon that’s 25% lighter than traditional acetate yet twice as strong. This injection-molded material resists deformation over time, handles temperature extremes without becoming brittle, and provides controlled flexibility for improved impact resistance. You get a frame that’s comfortable enough for all-day wear but tough enough to keep up with active lifestyles.
TruBridge Technology and Adjustable Fit
Fit matters when you’re wearing glasses from morning to night. The Chamfer Squared includes TruBridge technology—four interchangeable nose pads that adapt to different bridge widths and depths for a truly personalized fit. Adjustable wire-core temples let you dial in the perfect temple angle, while Unobtainium sleeves on the ear stems increase grip as moisture builds, preventing slippage during activity or in warm conditions. The result is a secure, pressure-free fit that stays put.
Prescription-Ready Square Frames
These full-rim frames are designed for prescription lenses and work well with single vision, progressive, and bifocal prescriptions. The 54mm lens width and 16mm bridge suit medium to larger faces, and the square shape complements round, oval, and heart-shaped face structures. Available in Satin Black, Satin Grey Smoke, and Universe Blue finishes.
