Abstract (en)
[origin: WO2004070427A2] The invention relates to a method using visible and/or near-ultraviolet light for the photopolymerisation of a composition free from mineral particles, comprising at least one photopolymerisable monomer and at least one photoinitiator which is selected from suberone derivatives and mixtures of an alpha -diketone and an organic peroxide. The invention is suitable for use in the production of ophthalmic lenses.
