This frame features a three-point design with aviator lens shape. Three-point frame design means there is no frame around the lenses and temples and bridge simply screw onto the lenses at three points. Aviator lens shapes have been around for many years and for good reason, they fit the human face form very well. The frame has an 8R wrap meaning it wraps around your face to protect your eyes from glare and harmful UV wavelengths at every angle.
