摘要:
An optical lens including, an object-side surface including an atoric surface element and an eyeball-side surface including an element that cancels a surface power shift produced by the atoric surface element, wherein the atoric surface element causes horizontal surface power at a fitting point to be greater than vertical surface power at the fitting point and causes a difference between the horizontal surface power and the vertical surface power to decrease along a horizontal reference line passing through the fitting point in a direction from the fitting point toward a periphery of the optical lens or causes a sign of the difference between the horizontal surface power and the vertical surface power to change along the horizontal reference line.

An eye-side refractive surface 11 of a distance portion is concave and at least part of an eye-side refractive surface 3 of a near portion is a convex region 31 where one or both of principal meridians of the surface are convex. This provides a back surface progressive-power lens capable of solving disadvantages in terms of lens thickness, external appearance and the like in a back surface progressive-power lens in which the eye-side refractive surface is formed of a progressive-power surface.

A lens order system, includes: a server unit, including: a data recognizer that recognizes lens design detail data relating to design details of a lens; an image storage that stores object image data relating to an image of an object; an image recognizer that recognizes the object image data based on the lens design detail data; and an order reception section that recognizes order data relating to an order for a designed lens and generates order reception data, and a terminal unit connected with the server unit in a data transmittable manner, the terminal unit including: a data acquiring section that acquires the lens design detail data; a lens design section that designs the lens based on the lens design detail data; an image processor that superposes lens image data relating to an image of the designed lens designed by the lens design section on the object image data sent from the server unit and generates processed image data in which a superposing portion of the object image data and the lens image data is image-processed to provide a vision of the object image data through the designed lens; a display controller that displays the processed image data on a display; and an order section that generates the order data.
摘要:
A progressive addition power lens with a length of the intermediate corridor in the range of 22 to 28 mm, and a clear visual region, which is defined as a region where astigmatism is 0.5 diopters or less, has a horizontally maximum width thereof in the distant dioptric power region, which is twice as thick as or less than a horizontally minimum width in the intermediate corridor. Furthermore, the clear visual region defined as a region where astigmatism is 0.5 diopters or less has a width of 30 mm or more horizontally in the near dioptric power region. In addition, a position, where astigmatism distributed at the sides of the lens has the maximum value, is located in an almost horizontal direction with a far point positioned above the intermediate corridor or is located above the far point.
摘要:
A method for providing design data and a system for providing design data that enable a lens processor to manufacture a desired inner-surface progressive addition lens corresponding to prescription data. A design data providing system is a system such that a design data creator provides design data of an inner-surface progressive addition lens to a lens processor in the case where the lens processor has agreed upon a contract to the effect that the lens processor receives provision of the design data of the inner-surface progressive addition lens from the design data creator on the condition that the lens processor pays a consideration. The design data providing system has a server device as a host computer device, a terminal computer device, and a network for connecting the server device to the terminal computer device.

A combined spectacle lens including a combination of a basic lens and an auxiliary lens, the basic lens formed with a progressive-power surface having a first power portion having a power for viewing an object at a predetermined distance, a second power portion having a power different from that in the first power portion, and a progressive portion in which the power is progressively changed from the first power portion to the second power portion on either one or both of refractive surfaces on an object side and an eyeball side, wherein a resultant power obtained by combining a basic lens power of the basic lens and an auxiliary lens power of the auxiliary lens is partly or entirely different from that of the basic lens power.
