Spring Hinge Eyeglasses
Spring hinges provide a closer fit than standard barrel hinges. Small springs in the hinges of this eyewear allow temples a wider range of motion than the standard 90 degree angle. Spring hinge eyeglasses can also serve as safety glasses for some applications. Hinge springs allow the temples to hug your face and remain in place as you move.
