  • Patent number: RE36302
    Abstract: Male and female members for contact lenses where either member is able to hold the contact lens as it moves from station to station during the hydration process. The female member fits together with the male member forming a chamber. Each of the members contains a line centrally located so that both surfaces of the contact lens are flushed during the hydration process, and drainage takes place radially on the outside of the mated male and female chamber members. These members may be produced on a frame with a plurality of members, usually eight to a frame, to allow ease of processing. Full automation is possible, and complete and positive lens control during and step of the process through the packaging step is achieved.
