ABSTRACT:
A soft contact lens container is disclosed for the immersion, preservation, optical measurement, shipping and dispensing of soft contact lenses. The container has an overall cylindrical shape with the cylinder sidewalls divided into mating portions for confining the soft contact lens as well as a liquid saline preservative solution. The cylinder ends are each closed by identical frustrated cones, each cone intruding from the cylinder end and into the cylindrical volume interior of the container. The respective cones from each cylinder end are frustrated by optical flats and confront one another with a small spatial separation so that the soft contact lens is trapped therebetween. Cylinder diameter is chosen to restrict the soft contact lens from passing between the two optical flats of the cone frustrum. In operation, one cylindrical section is filled with soft contact lens saline solution. A soft contact lens is immersed in the solution and the case closed with the remaining and confronting cylindrical lens portion. When equilibrium between the saline solution and soft contact lens is reached, measurement of the lens is made through the optical flats of the container, this measurement being the optical power of the lens or inside curvature of the lens. The container forms a convenient shipping media, minimizes the distorting effect of gravity on the soft contact lens, maintains the required saline solution as well as provides a shockproof environment for lens shipment.
