Abstract: A visual function examination device includes a response information acquisition unit configured to acquire response information indicating a response about glare felt by a subject to a visual target based on a glare illusion and a glare index calculation unit configured to calculate an index for the glare felt by the subject on the basis of the response information acquired by the response information acquisition unit.

Abstract: An oil-repellent coating layer 2 is disposed on both surfaces of a lens material 1 consisting of glass or a plastic. Furthermore, a minute particle layer 3 in 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 layer 2, and a resin layer 4 consisting of an organic compound is disposed on the surface of the minute particle layer 3. Since the adhesion between the resin layer 4 and 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.
