Abstract: To perform measurement in which a load on a subject is reduced. To provide a spectacle wearing parameter measurement system including: an information processing unit configured to associate a size of an appearance of at least a part of actual spectacles with a size of an appearance of at least a part of each of the spectacles in an imaging result of imaging a subject wearing the actual spectacles as an imaging target, and obtain a spectacle wearing parameter from the imaging result and the related art of the system.

Abstract: A spectacle wearing parameter measurement device used in measurement of a spectacle wearing parameter of a subject who is to wear a spectacle frame, the spectacle wearing parameter measurement device includes: an information processing unit that acquires each of a first image as a face image of the subject in a spectacle-frame wearing state and a second image as a face image in a spectacle-frame non-wearing state and prepares a third image obtained by associating the first image and the second image; a display screen unit that displays the third image prepared by the information processing unit; an operation unit that specifies a measurement reference point of the spectacle wearing parameter on the third image displayed on the display screen unit; and a measurement computation section that calculates the spectacle wearing parameter by using data of the specified measurement reference point.

Abstract: An aspect of the present invention relates to an eyeglass lens comprising a lens substrate and a vapor-deposited film either directly or indirectly on the lens substrate, wherein the vapor-deposited film is an oxide film of metal selected from the group consisting of zirconium and tantalum, with an average grain size observed in a planar image obtained by a transmission electron microscope of equal to or greater than 3.5 nm and a proportion accounted for by grain boundaries, which are boundaries separating grains from regions outside of the grains, in a planar image obtained by a transmission electron microscope of less than 15%.

Abstract: An aspect of the present invention relates to a method of manufacturing an eyeglass lens having a functional film on a lens substrate, which comprises determining materials for manufacturing an eyeglass lens by implementing a prescribed material determining method and manufacturing an eyeglass lens by use of the materials that have been determined.

Abstract: An aspect of the present invention relates to a method of evaluating performance of a film-forming material for forming a functional film on an eyeglass lens substrate or a functional film formed by the use of the film-forming material. The performance to be evaluated is selected from the group consisting of a sliding sensation of a surface of the functional film and an adhesion of the functional film, and the evaluation is conducted based on a change over time in a quantity of photoelectrons generated by irradiating with an X-ray the film-forming material or the functional film.
