摘 要：Resin lens are very popular in glasses market. Many technologies have been developed to coat different thin films on resin lens to strengthen its resistance to scratch or wear, but little of the scratch failure mechanism of such thin films are reported. This paper presented the results of several scratch tests performed on three resin lenses coated with different thin films at the normal loads of 98 mN and 49 mN and at sliding velocity of 0.003 3 m/s and 0.001 7 m/s, and the observation of the scratch tracks on the resin lens by SEM. It shows that the resin lenses coated with different thin films have different scratch resistance and different scratch failure mechanism, and the scratch resistance varies at the two different loads and sliding velocity. The experiment provides a new method to evaluate the scratch resistance of resin lens.
