Eyeglasses hinges are the joints that allow the glasses temples to fold open and closed and affect the way that the frames fit the face. There are three types of hinge glasses: spring hinge glasses, barrel hinge glasses, and hingeless glasses. Eyeglass hinges are not just a critical component of eyewear, they are the most important part of any pair of glasses. Whether they are eyeglass hinges or sunglasses hinges, due to the wear and tear of consistent use, the hinges will weaken and loosen over time, though they are generally easy to repair and tighten.
