ABSTRACT:
A device for aid in inserting or removing a contact lens including an elongate, resilient, cylindrical tube having a contact lens holding cup formed at one end thereof communicating with the interior of the tube. A light transmitting closure member is press fit in the opposite end of the tube to provide an airtight closure at that end of the tube. Opposite sides of a resilient portion of the tube are manually flexible toward and away from each other to evacuate a portion of the tube and, upon release and with a contact lens seated on the lens holding cup, return to their original configuration to produce a subatmospheric pressure within the tube to hold the lens on the lens holding cup. An elongate, light transmitting, manually incompressible shaft extends longitudinally through the interior of the tube to prevent opposed sides of the tube from being squeezed completely together, thus to provide a light transmitting path between the closure at one end and the lens holding cup at the other end to aid in sighting through the device during operation.
