These hinges are equipped with a small spring that affords the arms a greater range of movement and does not limit them to the traditional, 90 degree angle. These hinges provide greater comfort for the wearer and are more able to withstand everyday use. Most Spring Hinges are constructed with 3 barrels. These RayBan RX5268’s are a good example of the spring hinge. Weight is also awkward in that just a few grammes difference can be felt by the wearer.

Eyeglasses hinges are a pivotal element in the creation of frames. These hinges are the minute mechanism that connect the front of the frames to the arms that rest on your ears. Plastic glasses frames which have snapped at the bridge can be repaired using adhesive or nail polish remover which contains acetone. Ideally the bond should be supported using tape or better still, heat-shrink tubing. Metal frames broken at the bridge are less easily repaired, but a similar method can be used.
