Abstract

910,455. Contact lens. SOKEL, E. Feb. 17, 1961, No. 5923/61. Drawings to Specification. Class 97 (1). A corneal lens has a removable additional lens adapted to be located over at least part of the front surface of it and having a rear surface (preferably concave) substantially corresponding to that part of the front surface of the corneal lens with which it is to contact. In this way a bifocal contact lens is produced. The additional lens may be semicircular or crescent shaped.
