Abstract: PURPOSE:To reduce or eliminate malodor generated in the stage of cutting or grinding work of a plastic lens by incorporating a fragrance imparting compound among hydrocarbon compds. or hetercyclic compds. to the plastic lens. CONSTITUTION:0.005-1.0wt% at least one kind of fragrance imparting compd. selected from hyrocarbon or heterocyclic fragrance imparting compds. having at least one OH, aldehyde, carbonyl or ester group, is incorporated into a plastic lens having >=1.50 refractive index and crosslinked structure. Above 1pt.wt. content of the fragrance imparting compd. per 100pts.wt. monomer is undesirable because of too strong shedding, even in normal state holding its usual shape, of the perfume, and of decreasing the mechanical characteristic of the molded body to be obtd. If the amt. to be addes is
