Provided is a polymerizable non-aqueous dispersion, wherein the non-aqueous dispersion comprises: (a) a polymerizable component; and (b) polymeric microparticles dispersed in a continuous phase, wherein the microparticles comprise a dispersion polymerization reaction product prepared from a reaction mixture comprising an ethylenically unsaturated monomer, and an acrylic polymer stabilizer, and wherein the continuous phase is the same as or different from the polymerizable component (a). Also provided are optical articles prepared from the polymerizable non-aqueous dispersions.
