Your plastic frame comes apart, they're out of warranty and your eyeglasses are not replaceable with your vision insurance for a few months--so now what do you do? Plastic eyeglass frames are popular because they are lightweight, colorful and available in many different styles. Over time, the plastic material becomes warped, brittle or cracks or breaks. There are several ways to fix broken plastic eyeglass frames at home.
Lay the towel on your work surface and place your tools, cotton swabs and alcohol on the towel. This helps to keep everything in one place, protects your table or counter and also helps to prevent losing small pieces from your eyeglasses.
Examine the broken frame to see what needs to be repaired. If the temple, the part of the frame that rests on the ear, has separated from the front of the frame, determine if the screw is missing or loose from the hinge or if the hinge is completely broken off.
Tighten or replace any missing or lose screws. If the hinge is broken, moisten the cotton swab with alcohol and clean the frame and the hinge. Allow to air dry. Once dry, apply a few drops of bonding glue to the inside of the frame where the hinge attaches and place the hinge piece carefully so that it rests in the correct position. Use the hinge on the other side of the frame for reference.
Repair a broken bridge, the center of the frame that rests on the nose, with bonding glue. Clean both sides of the frame with the alcohol and cotton swab and allow to dry. Place a few drops of glue on one side of the bridge and reattach the other piece and hold firmly for about a minute to ensure the pieces adhere to each other. Be careful not to get glue on the lenses.
Tighten a warped or stretched out plastic frame by immersing the frame in very warm, but not boiling, water. Fill a sink with very warm tap water and place your glasses in the sink for a few minutes. Remove the frame and gently bend the front to reshape and curve the frame to match the curve of your face. This has to be done gently. Do not bend too far or the lenses may pop out. While the frame is still warm, gently bend the curve of the temple, the part where the frame rests over your ears, down slightly if your frame is too loose and slides down on your nose.
