An ophthalmic mounting for bifocal lenses includes a pair of rims on which a pair of right and left bifocal lenses are mounted. The rims are symmetrically arranged with respect to a vertical axis. The ophthalmic mounting includes a pair of pad arms connected to the rims, and a pair of nose pads detachably secured to the pad arms and oriented to diverge downwardly from the vertical axis. The nose pads includes a pair of generally flat bodies, a pair of guides integrally formed in the bodies and having a pair of elongated guide recesses, and a pair of slides. The slides have a pair of sliding portions slidably received within the respective guide recesses, and a pair of mounting portions connected to the respective sliding portions and detachably secured to the pad arms. The guide recesses lie on two substantially parallel imaginary vertical planes, respectively so as to enable the slides to be smoothly moved along the guide recesses.
