If ordinary sunglasses just dont fit, Fives Squared is the answer. Unlike conventional sunglasses that stick out at the sides, this frame uses Condensed Cranial Geometry for a tapered architecture that feels as good as it looks. Dimensional reliefs, metal icons and sculpturally integrated hinges take the whole idea of street-smooth style and amp it with attitude. Oakley's Three-Point Fit maximizes comfort while holding the lenses in precise optical alignment, letting the innovations of High Definition (HDO) do their work. Optical performance and impact protection meet ANSI Z87.1 standards, and with 8.75 base lens curvature, youll have extended peripheral vision and improved side protection against sun, wind and impact. Patented XYZ Optics helps keep vision sharp at every angle of view. This pair of sunglasses was engineered with durable yet lightweight O Matter and matched it with pure Plutonite lenses that filter out all UV.
