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: A method for designing, by means of a computer, at least one surface of a lens for a user. The method includes the steps of (i) obtaining displacement information on an amount of displacement between a user specific fitting position and a reference position, the reference position representing a primary fitting point of a lens surface on a reference line of sight of an eye of the user, and the user specific fitting position representing a user specific fitting point of the lens surface determined on the basis of the user; and (ii) causing calculating a design of the at least one surface of the lens on the basis of said displacement information.
