A lens system for variable refraction comprising a solid housing having a single internal chamber completely filled with a plurality of imiscible liquids of preselected densities and refractive indices. The chamber is of a form such that the amount and distribution of each liquid in the optical portion of the system is altered when the system is tilted, producing a change in refractive power. The system may be incorporated into spectacle lenses or contact lenses to provide a continuous spectrum of refractive power, or into contact lenses to provide bifocal capability.
