ABSTRACT:
Aims to enable to supply an optimal and dedicated spectacle lens or spectacle for each spectacle wearer, and also to verify a spectacle wearing state appropriately.A spectacle wearing parameter measurement system, sets a spectacle wearer to be in a distance vision state or a near vision state in which, in the near vision state, at least, one of an eyeball rotation angle and a near vision target distance is changeable optionally; takes an image of the spectacle wearer set in the distance vision state or near vision state by an image pickup device; imports the image; and measures and calculates a spectacle wearing parameter based on the image. A server computer of a factory received the image uses the image data to manufacture a spectacle lens or a spectacle. Further, a spectacle wearing test system verifies whether or not a spectacle wearing state is appropriate based on a figure obtained by a comparison comparing a spectacle wearing parameter measured at present time after manufacturing the spectacle and the spectacle wearing parameter before manufacturing the spectacle.
