  • Patent number: 11396148
    Abstract: A method for making an improved contact lens with the steps of providing a mold with a space between the top surface and a bottom surface, and positioning a mat in the space of the mold, providing a bead of liquid polymer of predetermined size at a predetermined location on the surface of the mat, pressing the bead of liquid polymer into the mat between the top surface and the bottom surface of the mold to form an optical zone framed by a mat peripheral zone, exposing the optical zone and the peripheral zone with U-V radiation to harden the optical zone into a composite improved contact lens, removing the cross-linked improved contact lens from the mold, processing the peripheral zone surrounding the optical zone to have a fenestration surface having holes, the holes being through holes with predetermined diameters selected to pass larger proteins, lipids, metabolites.

  • Patent number: 5478239
    Abstract: An apparatus and method for improving physical coordination and ability to react to moving and stationary objects is disclosed herein. A pair of voltage controlled liquid crystal lenses (14, 16) are mounted in a support frame (12) which is worn by a user in the same manner as conventional eyeglasses. The lenses (14, 16) can be electronically pulsed between an opaque state and a transparent state. Further, the lenses (14, 16) scatter background light in their opaque state rather than block the light so as to provide a generally constant level of contrast and brightness. This prevents pupil dilation changes when switching between the transparent state and the opaque state. Each lens can be made to pulse from an opaque state to a transparent state and then back again, and can be controlled independently or in synchronization. In operation, the user adjusts the control unit (18) to pulse the lenses (14, 16) at a high speed. An object is then viewed through the lenses and an appropriate response is made.
