METHOD OF MAKING CONTACT LENSES WITH IDENTIFYING MARK

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<2> and a lower intensity in the wavelength range of 250-260 nm by at least 10 mW/cm<2> than the second high inten¬ sity UV light.
