Spectacle lens design system, supply system, design method and manufacturing method |
摘要 |
A spectacle lens design system, including: an eyeball rotation center determination means that identifies an corneal apex position of an eye of a subject based on an image photographed by a predetermined photographing apparatus and determines an eyeball rotation center position of the subject based on the identified corneal apex position; a visual line information calculation means that calculates visual line information of the subjected defined when the subject watches a visual target disposed at a predetermined position, based on the eyeball rotation center position determined by the eyeball rotation center determination means and the position of the visual target; and a shape design means that designs a shape of a spectacle lens based on predetermined prescription information and the visual line information calculated by the visual line information calculation means. |
