ABSTRACT:
Apparatus for inserting a lens into the eye opening of an eyewear frame front includes a lens-seating surface on which a lens is placed. The lens-seating surface is reciprocally movable within a lower block. An upper block is reciprocally movably along a common vertical axis with respect to the lower block such that the upper block can be alternately raised and lowered relative to the stationary lower block. The upper block releasably carries a stretching cone which is placed on top of the lens on the lens-seating surface; the upper block is then raised while leaving the cone on the lens, and the eye opening of a heated front frame is placed over the stretching cone. The upper block is again lowered to capture the frame portion surrounding the eye opening, and the lens-seating surface is raised to force the cone through the eye opening. Once the cone has passed entirely through the eye opening, the lens is positioned within the eye opening of the frame, and the upper block is raised, carrying the cone with it, and thus revealing the frame having the lens inserted within the eye opening.
