    摘要： The present invention relates to a process for producing a cyanopsia-correctable intraocular lens, which process is characterized by, in polymerizing a monomer capable of forming a transparent lens material upon polymerization to obtain an intraocular lens, adding, as an essential component, at least one member of yellow, yellowish brown and orange colorants and, as an optional components, an U.V. absorber and a crosslinking monomer. The intraocular lens obtained by the present invention has a light absorption characteristic close to that of human crystalline lens and is effective for correction of cyanopsia.

    摘要： A contact lens material which is suitable for producing a contact lens having intermediate and low hydrous nature and which has hardness suitable for machining by cutting and polishing, is formed of a copolymer obtained by copolymerizing a monomer mixture which contains, based on 100 parts by weight of the monomer mixture, 35 to 65 parts by weight of at least one fluorine-containing monomer of the formula (I), ##STR1## wherein R.sub.1 is CH.sub.3, R.sub.2 is H or CH.sub.3, a is an integer of 1 to 9, m is an integer of 1 to 5, n is an integer of 4 to 10, p is an integer of 8 or greater, q is an integer of 0 or greater, and p, q and n have the relationship of p+q=2n+1,and 30 to 45 parts by weight of at least one amide group-containing monomer as essential components and which also contains other monomer as an optional component. The contact lens is obtained from the above contact lens material.
