Abstract
An optical device comprising a pair of lenses mounted along a viewing axis within a housing and angularly adjustable relative to the viewing axis by a manipulator extending outside the housing. The manipulator comprises an exterior knob on a shaft extending through the housing and having a gear engaging corresponding sector gear portions of individual pivoted mounts supporting the respective lenses. A flexible, preferably elastic membrane, sealed to the respective lenses and extending therebetween, contains a fluid such as glycerine, having an index of refraction corresponding to the refractive index of the lens material. Adjustment of the manipulator knob jointly varies the angles of the respective lenses relative to the viewing axis and to each other so as to shift the direction of light transmitted through the device. The device is used by an individual in exercising eye muscles to correct a condition of squint, e.g., the cross-eyed condition not infrequently encountered in young children.
