ABSTRACT:
A kit for repairing an eyeglass frame that has lost a hinge pin comprises a container with at least one hinge pin therein, the hinge pin being locally plastically deformable at one end thereof, and instructions for installing the hinge pin in the frame. The replacement hinge pin is deformable either by softening or melting with a small flame or other heat source, or alternatively has a soft end portion which is mechanically deformable. A user of the kit deforms a first end of the pin to form a first end with a diameter greater than the maximum body diameter of the hinge pin, inserts the pin into a hinge of the eyeglass frame, and then deforms a second end of the pin to form a second end with a diameter greater than the maximum body diameter of the hinge pin, so that an earpiece of the frame becomes pivotally secured by the pin.
