  • Pupil-only photochromic contact lenses displaying desirable optics and comfort
    Patent number: 11789291
    Abstract: A method for making a hydrogel, photochromic contact lens including supplying a first lens composition comprising a contact lens monomer and a photochromic material to a front contact lens mold and supplying a second lens composition to said contact lens mold wherein the viscosity of said first composition is at least about 1000 cp greater than the viscosity of said second contact lens composition, and the makeup of said second composition matches the of said first composition to reduce strain between said compositions of the resulting lens.

  • METHODS FOR THE MANUFACTURE OF PHOTOABSORBING CONTACT LENSES AND PHOTOABSORBING CONTACT LENSES PRODUCED THEREBY
    Publication number: 20230286232
    Abstract: Provided is a method for manufacturing photoabsorbing contact lenses and photoabsorbing contact lenses produced thereby. The method comprises: (a) providing a mold assembly comprised of a base curve and a front curve, the base curve and the front curve defining and enclosing a cavity therebetween, the cavity containing a reactive mixture, wherein the reactive mixture comprises at least one polymerizable monomer, a photoinitiator which absorbs at an activating wavelength, and a photoabsorbing compound which displays absorption at the activating wavelength; and (b) curing the reactive mixture to form the photoabsorbing contact lens by exposing the reactive mixture to radiation that includes the activating wavelength, wherein the radiation is directed at both the base curve and the front curve of the mold assembly, and wherein the radiation's radiant energy at the base curve is greater than the radiation's radiant energy at the front curve.
