Abstract
A monomer as represented by general formula (a) or (a′) below, with which a polymer having high oxygen permeability and transparency and suited to an ophthalmic lens is obtained, is provided. Suitable monomers have the formula: 1 wherein A is a siloxanyl group; R1 and R2 are H or methyl groups; R3 is a substituted group that is selected from the group consisting of alkyl groups with 1 to 20 carbon atoms that may be substituted and aryl groups with 6 to 20 carbon atoms that may be substituted; m indicates an integer of 0 to 200.
