PROBLEM TO BE SOLVED: To provide a lightweight spectacle frame on which right and left spectacle lenses are opened and closed independently, and also to provide a spectacle hanger which is detachably mounted on the spectacle frame. SOLUTION: The spectacle frame 10 of the present invention which has a couple of lens hangers 20 having lens stoppers 26 at ends and a couple of fixing bridges 19 supporting base ends of the lens hangers 20 rotatably on right-left axes has support holes 16 that the fixing bridges 19 penetrate in the right-left directions, outer peripheral surfaces 17 which are concentric with the support holes 16 and have a specified radius of curvature, and annular grooves 16 which are formed on the outer peripheral surfaces 17. The lens hanger 20 is made of a metallic wire material and has: support shaft parts 21 which are fitted rotatably in the support holes 16 of the fixing bridges 19; engagement parts 22 which engages the annular grooves 18 of the fixing bridges 19; and spring parts 27 which are formed between those support shaft parts 21 and engagement parts 22, and elastically energize the engagement parts 22 toward the annular grooves 18, no screw being needed.
