A spectacle support includes a unitary strip of spring steel material bent to provide a central curved forehead-engaging portion and a pair of rearwardly and extending arm portions which extend inwardly and downwardly behind the rear of the head of a wearer. The arm portions are stepped outwardly from the forehead-engaging portion, so that when positioned on the head of a wearer, the portions of the spectacle support overlying the temples are spaced outwardly off the temples and apply no pressure to them. By shaping the arm portions of the support, a single size can be worn comfortably by people having a wide range of head sizes and shapes. A lens sub-frame is secured to the central region of the spectacle support for attachment of the lenses. In certain preferred embodiments the support is hingedly coupled with the spectacle support and the lens sub-frame, to permit adjustment of the vertex distance of the lenses from the eyes of the wearer. In one embodiment the stepped portions of the frame may be bent so that the transverse dimension of the central portion extends horizontally, while the transverse dimension of the arm portions extends vertically, to provide added stiffness to the forehead portion of the support.
