Surface modified optical lens and method of surface modification

Abstract From the Canadian patent

An optical lens of an acrylic polymer having an outermost surface modified in molecular structure to possess a desired characteristic. The modified surface includes a select chemical group, having the desired characteristic, bound by silane groups to reactive carboxyl groups on polymer chains of the acrylic polymer at the outermost surface of the lens. The surface is modified by a surface activating hydrolysis reaction chemically linking active carboxyl groups on polymer chains at the outermost surface of the acrylic polymer and then modifying the activated outermost surface by reacting a reagent including a select chemical group having the desired lens surface characteristic with the …
