Abstract
A spectacle lens optical value determining method, a spectacle lens manufacturing method, a spectacle lens, and an order placing/receiving system of the same, which enable minimization of “sway” and “distortion” that one feels when wearing spectacles, are provided. An optical value of a spectacle lens is selected and determined so that a wavefront entering an eye of a subject at the time of optometry and a wavefront entering the eye when the subject wears the spectacle lens and views an object coincide with or are approximate to each other.
Claims19
A spectacle lens optical value determining method for determining an optical value including a refractive power of a spectacle lens suitable for a subject based on at least a prescription value including a refractive power data obtained from optometry using a trial lens, wherein the optical value of the spectacle lens is selected and determined so that a wavefront entering an eye of the subject at the time of optometry and a wavefront entering the eye when the subject wears the spectacle lens and views an object coincide with or are approximate to each other.
