Lenses of allyl-N-ethylene glycol carbonate having enhanced resistance to scratching or abrasion can be formed by preparing a substrate of a polymer or copolymer of allyl-N-ethylene glycol carbonate, the substrate being at least partially polymerized. A thin film of a copolymer of allyl-N-ethylene glycol carbonate and of an allyl monomer is formed by overmolding on the substrate and polymerized. |
