Document Type and Number:
WIPO Patent Application WO/2015/125847
Kind Code:
A1
Abstract:
As a configuration for an aligning prism amount determination device that determines the aligning prism amount required to correct fixation disparity in the wearer of a spectacle lens having fixation disparity, the present invention is provided with a determination unit (11) that determines, on the basis of a first aligning prism amount obtained by measuring the aligning prism amount of the wearer at an eye examination distance that corresponds to a first distance, a second aligning prism amount obtained by measuring at an eye examination distance that corresponds to a second distance which is shorter than the first distance, and information used in the allocation of the first aligning prism amount and second aligning prism amount, an aligning prism amount to be provided uniformly to a spectacle lens in order to correct fixation disparity, said amount being in a prism prescription range that is between the first aligning prism amount and the second aligning prism amount.
