Big single-lens styling hit the slope back in the late Seventies but Oakley's Riddle eliminates the vintage optical distortion with a contemporary Polaric ellipsoid lens design. Oakley's Polaric ellipsoid design shapes the Plutonite lens surface so it runs parallel to the shape of your eye transforming shadowy blurs into sharply defined images. While the generous dimensions tend to look best on large faces (especially the darker frames and lenses) the O Matter frame material is surprisingly lightweight and fits comfortably without the need for those old-fashioned foam fit pads that your parents (or grandparents) used to wear over their noses.
