In a spectacle frame each lens surround is formed by a relatively rigid rail and a flexible retaining member attached at each end to the rail. To effect this attachment the ends of each rail are formed with two transverse holes through which the flexible retaining member is passed twice. Each nose pad of the spectacle frame is also formed with two transverse holes through which the flexible retaining member may be passed twice. The holes in each nose pad correspond to those in the nose end of the associated rail, so that the nose pad may be attached to the rail by means of the flexible retaining member holding a lens in position in the surround.
