Abstract: A spectacle frame comprises a substantially straight or slightly curved structure composed of two rims and a bridge, and two temples. The bridge is connected between the two rims. One end of each temple is rotatably connected with an outward portion of a respective rim via a hinge. Each temple is formed into a bow-shaped bar that has a front portion, a middle portion, and a rear portion. The spectacle frame is designed to have a predetermined first parameter, a predetermined second parameter, a predetermined third parameter, and a predetermined fourth parameter, whereby the spectacle frame has a size smaller than general glasses to facilitate a person engaging a special task to wear a protective shield and prevent the protective shield from being interfered with, and can perfectly fit various facial profiles of persons so as to keep the protective shield airtight.

Abstract: The present invention is to provide an eyeglass temple structure, which includes a temple having a plate-shaped body formed with a through hole, a temple connector being extended with a fixing ring, and a pivotal hinge structure including a cylindrical pivot body and a fastening insert. The pivot body has a middle section formed with a groove for engaging with the fixing ring, and is axially formed with an aperture. The fastening insert is engaged in the aperture and can pivot with the pivot body, so as to form the pivotal hinge structure having replaceable elements for pivotally connecting the temple to the temple connector and allowing the temple to pivot with respect to the temple connector. Thus, the pivotal hinge structure can be easily engaged with the fixing ring via the groove of the pivot body and inserted in the through hole of the temple.
