Abstract
Abstract A soft contact lens apparatus formed of a resilient material having a generally U-shape. A control portion forms the seat of the U-shape, while an intermediate fulcrum section operates to spread forwardly located finger and tip means as said control portion is squeezed together. When released, the material's resiliency allows the tips to return to their substantially closed position. This return movement is used to pinch the soft contact lens from the eye without injury or damage to the eye or lens since the tips are made of soft yet firm material, and the amount of force is slight and predetermined by the natural resiliency of the material. The apparatus may also be used to insert the lens.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
131 words
A soft contact lens apparatus comprising a clamp having a control portion, an intermediate portion, and clamp fingers, said intermediate portion comprising a fulcrum with said control portion being defined rearwardly of said fulcrum and said clamp fingers being defined forwardly of said fulcrum, said control portion opening said fingers when said control portion is squeezed together, said fingers being opened to no greater than substantially the diameter of a soft contact lens, said clamp fingers terminating forwardly in outwardly flared engaging resilient contoured surfaces with respect to a longitudinal axis of said apparatus, said flared contoured surfaces holding said contact lens, said surfaces moving together pinching said contact lens together as the control portion is released to remove the lens from the eye, said contoured surfaces holding said contact lens.
Claim 2
Dependent Claim
131 words
A soft contact lens apparatus comprising a clamp having a control portion, an intermediate portion, and clamp fingers, said intermediate portion comprising a fulcrum with said control portion being defined rearwardly of said fulcrum and said clamp fingers being defined forwardly of said fulcrum, said control portion opening said fingers when said control portion is squeezed together, said fingers being opened to no greater than substantially the diameter of a soft contact lens, said clamp fingers terminating forwardly in outwardly flared engaging resilient contoured surfaces with respect to a longitudinal axis of said apparatus, said flared contoured surfaces holding said contact lens, said surfaces moving together pinching said contact lens together as the control portion is released to remove the lens from the eye, said contoured surfaces holding said contact lens.
