US Patent 10444533 Eyewear with removable lenses

An eyewear assembly has a frame with removable lenses. The eyewear assembly may include upper and lower frame portions that are separable from one another at a bridge region of the frame using a linkage. A finger actuator actuates the linkage to cause the upper frame to move away from the lower frame, exposing at least one edge of the lenses for removal. The separated upper frame portion and lower frame portion may be held in a stable open position. After lens removal or replacement, the linkage may be actuated to reconnect the upper frame portion and lower frame portion, thereby enclosing the lenses.
