Abstract:
A progressive-lens designing system includes a manufacturer-side terminal installed in a lens manufacturer connected to a shop-side terminal installed in a spectacle shop or any other location via a network. The manufacturer-side terminal includes an optimization coefficient setting section that uses a variety of data received from the shop-side terminal to set an optimization coefficient for each target object in specific work, a dioptric power computing section that computes target dioptric power for each target object, a lens designing section that performs lens design, and an order processing section that performs order processing when receiving an order placed from the shop-side terminal.
Abstract:
A spectacle lens includes: a near region corresponding to near vision, wherein a spherical equivalent power at a point located on a principal line of fixation in the near region is larger than the spherical equivalent power in a region away from the point toward the nose, in a horizontal direction with reference to a spectacle wearer but smaller than the spherical equivalent power in a region away from the point toward the ear in the horizontal direction.
