摘要： The present invention is related to a method for making silicone hy- drogel contact lenses with an identifying mark, by irradiating the iden¬ tifying mark coat on the molding surface with a first and a second high intensity UV light prior to filling the lens-forming fluid material; exposing the mold assembly and the lens-forming fluid material to an energy source which polymerizes the lens-forming fluid materi¬ al wherein the emission spectrum of the first high intensity UV light has a higher intensity in the wavelength range of 320-390 nm by at least 200 mW/cm and a lower intensity in the wavelength range of 250-260 nm by at least 10 mW/cm than the second high inten¬ sity UV light.

摘要： The present invention generally relates to a method for making colored contact lenses, in particular to colored silicone hydrogel contact lenses. The present invention is also related to a method of a first high intensity UV curing the colored print on the mold and a second high intensity UV treating mold for making colored silicone hydrogel contact lenses. The present invention illustrates the right combination of the first high intensity UV exposure and the second high intensity UV exposure allows a lens that maintains good ion permeability (IP) value and a good print quality.

摘要： The present invention is related to water-based inks for making colored hydrogel contact lenses, in particular, colored HEMA-based hydrogel contact lenses. The ink of the invention comprises at least one colorant, water, and a water-soluble and actinically-curable binder polymer which is a vinyl group-terminated polyurethane polymer, a vinyl group-terminated polyurea binder polymer, or a mixture thereof. Also, the ink of the invention is characterized by having a viscosity greater than 50 centipoise (cps), a prolonged stability, and a good adhesion to a HEMA-based hydrogel contact lens. The ink of the invention preferably further has a good compatibility with a HEMA-based hydrogel material, and/or good transferability from a mold to a HEMA-based hydrogel contact lens made in the mold. The present invention is also related to a method for making colored hydrogel contact lenses using an ink of the invention.

摘要： The present invention provides a chemical ink comprises a solvent, a binder polymer, a colorant and optionally a crosslinker. The ink of the invention has one or more of the following characteristics: a viscosity lower than about 50 centipoises; a surface tension of from about 20 mN/m to about 60 mN/m; a particle size of less than about 5 νm; prolonged stability; an appropriate color level (visible by eye); uniform drop formation; jet stability; good adhesion to contact lenses; good transfer from a mold to a lens made in the mold; and stability of ink in inkjet nozzles. The ink of the invention is useful for inkjet printing of a high-quality color image on a contact lens or a mold so as to produce a colored contact lens.
