Claim 13:
14. The cosmetic contact lens of claim 1, wherein the silicone-containing macromer comprises a chemical structure shown in Formula I:, wherein Z is selected from O, N, S or NCH2CH2O; when Z═O or S, R2 is not required; wherein R1 is a hydrogen atom or methyl; wherein n is a whole number between 1 and 200; wherein R3 is an alkylene segment (CH2)y in which y is a whole number from 1 to 6, and each methylene group may be optionally further and independently substituted with a group selected from the group consisting of ethers, amines, esters, ketones, carbonyls, carboxylates, and carbamates, or when y is 2 or more a non-terminal methylene group is optionally replaced with a carbamate group; or wherein R3 is an oxyalkylene segment O(CH2)z in which z is a whole number from 1 to 3, or wherein R3 is a mixture of alkylene and oxyalkylene segments and the sum of y and z is between 1 and 9; wherein R2 and R4 are independently a hydrogen atom, a linear, branched, or cyclic alkyl group containing between one and six carbon atoms, a linear, branched, or cyclic alkoxy group containing between one and six carbon atoms, a linear or branched polyethyelenoxyalkyl group, an alkyl-siloxanyl-alkyl group, a phenyl group, a benzyl group, a substituted or un-substituted aryl group, a fluoroalkyl group, a partially fluorinated alkyl group, a perfluoroalkyl group, a fluorine atom, a mono-, di, or tri-hydroxyalkyl group containing between one and six carbon atoms, or combinations thereof; and wherein R5 is a substituted or un-substituted linear, branched, or cyclic alkyl group having 1 to 8 carbon atoms or an aryl group, any of which may be further substituted with one or more fluorine atoms or trimethylsiloxy groups.
