摘要： A method of obtaining particulars or characteristics of an ophthalmic lens by detecting a fluorescent light which is emitted from the ophthalmic lens upon exposure to an excitation light (UV light). The particulars or characteristics of the ophthalmic lens include, for instance, identifying marks such as characters, figures, symbols, etc. which are formed in the ophthalmic lens to identify the ophthalmic lens, a thickness of the ophthalmic lens such as a contact lens and an intraocular lens, and an angular position of the ophthalmic lens, particularly of a special contact lens having circumferential portions having respective different thickness values.

摘要： It is an object of the present invention to provide an ophthalmic lens characterized in that it is capable of developing a color at a position where a light is irradiated, and to provide a marking method of the ophthalmic lens. It is another object of the present invention to provide an ophthalmic lens, which can form a clear and easily readable mark, without causing problems such as discoloration of the mark, caused by cleaning of the lens by rubbing, or deterioration of the mechanical strength of the lens, and to provide a marking method of the ophthalmic lens. The ophthalmic lens of the present invention is obtained by a polymerization of a polymerizable composition of monomers, which contains an alkyl (meth)acrylate as an essential polymerizable component, and this polymerization is carried out while the rhodamine derivative is existed in the composition.

摘要： An ocular lens having a desired shape without having a deformation induced by its process, and having a uniform coat layer on its surface, is proceeded by single mold polymerization. The ocular lens is produced by a process comprising a step of irradiating at least one part of the molding surface for the ocular lens of the mold with an excimer light, a step of coating a compound fixable to the ocular lens surface by an interaction with a polymerizable component in the ocular lens material, or its solution on the mold surface after irradiating with an excimer light, a step of filling the ocular lens material into the mold after coating, and polymerizing, a step of releasing a polymer obtained by the polymerization from the mold, and obtaining an ocular lens stock material having above-mentioned component fixed on its surface, and a step extracting unfixed unreacted components from obtained ocular lens stock material.
