Title:
コンタクトレンズの製造装置および形成方法
Document Type and Number:
Japanese Patent JP4004559
Kind Code:
B2
Abstract:
Disclosed are a method and apparatus for molding contact lenses by curing polymerizable compositions in suitably dimensioned molds using ultraviolet or other polymerization-inducing radiation and heat. The molds are moved along a source of radiation such that the intensity of the radiation to which the composition is exposed rises and falls several times, thereby achieving superior results by balancing the initiation and the propagation of the polymerization.
