ABSTRACT:
An oil-repellent coating layer2is disposed on both surfaces of a lens material1consisting of glass or a plastic. Furthermore, a minute particle layer3in which minute particles of a metal oxide or minute particles of a fluoride, or both, are dispersed is formed on the surface of the oil-repellent coating layer2, and a resin layer4consisting of an organic compound is disposed on the surface of the minute particle layer3. Since the adhesion between the resin layer4and the two-sided adhesive tape that is used when the lens is set in the lens edging machine is good, axial shifting tends not to occur during working.
