ABSTRACT:
An interchangeable sunglass system includes a frame, a first arm, a second arm, a quick release lens retainer, a soft nose piece, and a tinted lens. The frame has a first end, a second end, a top surface, and a bottom surface. An angled slot is formed in substantially the length of the bottom surface of the frame to accommodate the quick, and easy change of different tinted lenses. The angled slot allows a the tinted lens to angle inward toward the cheek of the user and allow the bottom of the tinted lens to rest close to the cheeks of the user. The first and second arms are pivotally connected to the frame. The quick release lens retainer includes a stem, a first leg, and a second leg. The stem extends downward from the frame. The soft nose piece is sized to be received between the first and second legs of the quick release lens retainer. Both cross sections of the length and the height of the tinted lens have the shape of a curvature. The tinted lens is removed by compressing the first and second legs of the quick release lens retainer with the thumb and fore finger until the tinted lens can be lifted above the quick release lens retainer. The tinted lens is inserted by compressing the quick release lens retainer and slipping the tinted lens into the angled slot and pushing the tinted lens on to the quick release lens retainer.
