Neu-Vita Oculizer
The Neu-Vita Oculizer, from England, uses a crank and pulley system to rotate both soft rubber eyecups. The other end of the instrument is fitted with hard rubber eyecups with a concave faced plunger to poke the eye when the rubber bulbs are squeezed. Vacuum can also be applied by covering an air hole and releasing the bulb. These devices were designed to modify the shape of the cornea by applying pressure or vacuum were marketed for at least seven decades. Most claimed to cure all types of eye problems and to render eye glasses unnecessary.
