This invention has the objective of providing polymers having high oxygen permeability and high hydrophobicity and ophthalmic lenses comprising said polymers, and, as a result, provides novel monomers represented by general formula (a) below: <CHEM> wherein, in formula (a), A<1> to A<9> indicate groups selected from the group consisting of H, alkyl groups, aralkyl groups, aryl groups and alkyl groups having 1 to 9 carbon atoms substituted with at least one group selected from epoxy groups, hydroxyl groups and amino groups, with at least one of A<1> to A<9> indicating said alkyl group of 1 to 9 carbon atoms substituted with at least one group selected from epoxy groups, hydroxyl groups and amino groups; a, b and c indicate 0 or 1; X indicates a polymerizable group having a carbon-carbon unsaturated bond; Z indicates groups selected from N-Y, O and S; Y indicates H, an alkyl group or an aryl group; and L indicates a divalent group having 1 to 10 carbon atoms. |
