Abstract: Provided is technology that makes it possible to design a progressive power lens appropriate for visual behavior of a subject. A method for designing a progressive power lens includes: a step (a) of determining a relationship between a line-of-sight passage position on a surface of a progressive power lens through which a line of sight of a subject wearing the progressive power lens passes and a reactive accommodation amount that the subject exhibits when the line of sight passes through the line-of-sight passage position, based on visual behavior of the subject; a step (b) of judging whether or not the reactive accommodation amount is within an appropriate range; a step (c) of determining a correction method for correcting the progressive power lens based on a result of judgement made in the step (b); and a step (d) of correcting a design of the progressive power lens based on the correction method determined in the step (c).

Abstract: Provided is a technique by which an optical member is marked without degrading the quality of the optical member. The optical member is produced through a removing step (S108, S113) of partially removing a low refractive index layer, which is the outermost layer of a multilayer structure in which the low refractive index layer and a high refractive index layer are layered on each other, by performing non-heating processing on an antireflection film that is formed to cover an optical surface of an optical base member and has the multilayer structure, through irradiation with an ultrashort pulse laser beam so as to expose the high refractive index layer.
