If you are tired of the cockeyed worldview that accompanies the sliding glasses syndrome, gather a few common household items and return your vision to normal. Repairing spring-hinged eyeglass frames can cost less than taking the glasses to an optometrist for repair. It will save you even more money by repairing your spring-hinged eyeglass frames instead of buying new ones. There is no need to buy brand new frames or spend extra money on paying for repairs when you can repair spring-hinged eyeglass frames at home.
Examine the spring hinge using a magnifying glass.
Press the safety pin against the base of the screw from the underside of the spring-hinge.
Maintain pressure on the safety pin while backing the screw out. The temple hole and the chassis hole remain properly aligned throughout the process.
Re-insert the screw. Retreat the safety pin so the tension on the spring-hinge does not slip before the screw is seated.
Dab a little nail polish on the screw's head. Let it dry.
Cover the eye glass lens with a cleaning cloth. Spray a small amount of WD-40 or another lubricant on the screw. Wait one minute. Wipe off the excess.
If you have a new screw the same size as the original, use the new screw in step 4 and skip step 5.
