A cracked eyeglass frame can be a disheartening sight, especially if you depend on the eyeglasses as your second set of eyes. If your favorite pair of eyeglasses have a cracked frame but are no longer under warranty and you are short on cash, try mending them with glue. While the fix may not be aesthetically pleasing or a forever solution, the glued frames may at least last you until your next paycheck.
Gather both ends of the cracked eyeglass frames. Sand the two broken edges using fine-grit sandpaper. You do not need to perform a heavy sanding; one or two swipes back and forth should suffice.
Apply a dab of quick-bond adhesive to one of the broken edges. For thin eyeglass frames, dab the glue onto a toothpick and transfer the glue to the frame using the toothpick instead of applying it directly to the broken edge.
Bring the two broken edges of the eyeglass frames together. Hold the eyeglass frames firmly together until the quick-bond glue adheres, which is usually within seconds of application. Wear the eyeglass frames as usual after gluing.
If the eyeglass frame cracks in an area that secures the lens and the lens falls out, replace the lens before gluing. Simply sand the broken edges and enclose the frame around the lens and secure the frames with the super-bond glue. Keep in mind that less is more when it comes to super-bond types of glue. No more than a drop or two should be necessary to repair cracked eyeglass lenses.
Apply the super-bond glue carefully and do not get the glue on your lenses. If you do happen to get glue anywhere that it is not wanted, try soaking the affected area with acetone nail polish remover.
