Claim:
An ophthalmic lens comprising a polymer comprising at least one residue of a compound having the structure: wherein M represents a radical-polymerizable group; wherein M is an acryloyloxy group or a methacryloyloxy group; wherein L represents an optionally substituted divalent C 1 -C 20 organic group substituted by hydroxy groups, hydroxyalkyl groups, amino groups, aminoalkyl groups, alkoxy groups, alkoxyalkyl groups, alkoxycarbonyl groups, alkoxycabonylalkyl groups or a combination of those functionalized groups; wherein Z 1 to Z 11 independently represent optionally substituted C 1 -C 20 alkyl groups, with the provisos that: when a is not 0, Z 3 , Z 4 , and Z 9 are methyl, ethyl, or propyl; wherein at least one of Z 3 , Z 4 , and Z 9 is methyl, and at least one Z 3 , Z 4 , and Z 9 is an ethyl or propyl, when b is not 0, Z 5 , Z 6 , and Z 10 are methyl, ethyl, or propyl; wherein at least one of Z 5 , Z 6 , and Z 10 is methyl, and at least one Z 5 , Z 6 , and Z 10 is an ethyl or propyl, and when c is not 0, Z 7 , Z 8 , and Z 11 are methyl, ethyl, or propyl; wherein at least one of Z 7 , Z 8 , and Z 11 is methyl, and at least one Z 7 , Z 8 , and Z 11 is an ethyl or propyl; wherein n represents an integer of from 0 to 200; wherein a, b, and c independently represent integers of from 0 to 20, with the proviso that a, b, and c are not simultaneously 0; wherein n=0; all of a, b, and c are 1; wherein a is 0; b and c are 1; and Z 9 comprises a methyl group, an ethyl group, a propyl group, or a butyl group; and wherein b and c are not simultaneously 0.
