Zusammenfassung: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 toform 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. 本发明提供了一种用于制造光吸收接触镜片的方法以及由此制备的光吸收接触镜片。该方法包括:(a)提供模具组件,该模具组件由底曲面和前曲面构成,该底曲面
