| titleOfInvention | Progressive power lens design method and progressive power lens design apparatus |
| abstract | A method of designing a progressive power lens with less image sway includes preferentially selecting a spectacle specification including a first condition if an average prescription power of a distance portion is equal to or greater than +3.0 D, and preferentially selecting a spectacle specification including a second condition if the average prescription power is equal to or smaller than −3.0 D. At least a surface power OHPf in a horizontal direction of a distance portion on an object-side surface is greater than a surface power OVPf in a vertical direction, or a surface power OHPn in a horizontal direction of a near portion is greater than a surface power OVPn in a vertical direction. The first condition includes a condition that the OVPf is greater than the OVPn, and the second condition includes a condition that the OVPf is smaller than the OVPn. |
