A process of fabricating a light-focusing plastic optical element includes preparing a prepolymer transparent preform. The prepolymer preform is immersed in a solution containing more than one monomer, each of the monomers having a different reactivity ratio from the other. Some of the monomers may permeate into and disperse in the preform so as to swell the prepolymer preform. The monomers dispersed in the preform are copolymerized after the preform is swelled completely to produce a plastic optical element.
