A lens having a high refractive index with a low dispersion produced by copolymerizing a polyfunctional allyl monomer with at least one monomer selected from the group represented by the general formula A: <IMAGE> A X: H, CH3, Cl Y: H, CH3, C2H5, n-C3H7, iso-C3H7, OCH3, C6H11, Cl, Br, CH2Cl, CH2Br, C6H5, CH2C6H5, SCH3 m=0, 1, 2 n=0, 1, 2, 3, 4, 5. This lens is excellent in its transmittance, pencil hardness, impact resistance, dyeability, coating adhesion, solvent resistance, workability, etc.
