SPECTACLE LENS AND METHOD FOR DESIGNING THE SAME, METHOD FOR MANUFACTURING SPECTACLE LENS, AND PROGRAM

摘要

A spectacle lens, which is a pair of spectacle lenses including a lens for a left eye and a lens for a right eye corresponding to left and right eyes respectively, wherein a lens power is set so that accommodation powers coincide with each other between right and left eyes, the accommodation powers being required for each of the right and left eyes calculated based on a distance between an arbitrary point on a virtual object surface and each of the right and left eyes, and the lens power at each passing point where an optical ray directed to this point passes through the lens for a left eye and the lens for a right eye, when the previously set arbitrary point on the virtual object surface is viewed in a binocular vision through the lens for a left eye and the lens for a right eye.

1. A spectacle lens, which is a pair of spectacle lenses including a lens for a left eye and a lens for a right eye corresponding to left and right eyes respectively, wherein each lens powers are set so that accommodation powers being required for each of the right and left eyes coincide with each other when an arbitrary point on the previously set virtual object surface is watched binocularly through each lenses for each eye. Wherein the accommodation power being required for each of the right and left eyes is calculated based on the distance from the eye to that arbitrary point on the virtual object surface, and the lens power at the passing point where the optical ray from that arbitrary point towards the eye passes through.
