  • Apparatus for applying contact lens
    Patent number: 6702348
    Abstract: A contact lens applicator comprises an external rubber air bladder with a connected tube. The tube would serve as a platform on which a user can place a contact lens that is about to be placed in an eye. Through a combination of suction from the tube (through the squeezing of the lower bulb) and the width of the first end of the neck, a user would be able to maintain a contact lens in a set position until the contact lens would be ready to be placed in a user's eye.
