Abstract:
The current disclosure is directed to a method for determining an improved design for a progressive spectacle lens. Further, there are provided a method for manufacturing a progressive spectacle lens, a system for determining an improved design for a progressive spectacle lens, a non-transitory computer program and a progressive spectacle lens.

Claim (Index 18):
A method for manufacturing a progressive lens, the method comprising the following steps:\n determining an improved design of the progressive spectacle lens, wherein said determining an improved design of the progressive spectacle lens includes:\n a) providing an aberration information of a wearer's eye, the aberration information comprising lower-order aberrations of the wearer's eye and higher-order aberrations of the wearer's eye, wherein the lower-order aberrations are aberrations up to and including second-order, wherein second-order aberrations vary as a function of the square of the distance of a center of the pupil of the wearer's eye; \n b) providing an initial design optical power distribution and a corresponding initial design of the progressive spectacle lens, wherein the initial design optical power distribution and corresponding initial design are provided taking into consideration only the lower-order aberrations of the wearer's eye and the lower-order aberrations of the progressive spectacle lens and assuming a predetermined position and orientation of said progressive spectacle lens in front of said wearer's eye as well as a predetermined model for the distances and positions in space for a plurality of objects in front of the wearer's eye viewed by the wearer; \n c) calculating a perceived optical power distribution perceived by the eye based on the initial design of the progressive spectacle lens and taking into consideration the lower-order aberrations and the higher-order aberrations of the wearer's eye of step a) as well as the lower-order aberrations and the higher-order aberrations of the progressive spectacle lens and assuming said predetermined position and orientation of said progressive spectacle lens in front of said wearer's eye as well as said predetermined model for the distances and positions in space for a plurality of objects in front of the wearer's eye viewed by the wearer of step b); \n d) calculating an improved design optical power distribution by translating the initial design optical power distribution of the progressive spectacle lens of step b) and/or rotating the initial design optical power distribution of the progressive spectacle lens of step b), such that a deviation between the perceived optical power distribution of step c) and the translated and/or rotated initial design optical power distribution is minimized; and \n e) calculating the improved design of the progressive spectacle lens by at least one of:\n translating and/or rotating the initial design of the progressive spectacle lens of step b) according to the calculated translation and/or rotation of step d) and \n optimizing a starting design of the progressive spectacle lens by using the improved design optical power distribution of step d) as a target design optical power distribution; and, \n \n manufacturing the progressive spectacle lens with the determined improved design.
