A method of determining binocular performance of a pair of spectacle lenses comprises: a eyes characteristics providing step, a pair of spectacle lenses providing step, a environment providing step, a binocular performance criteria selecting step, and a binocular performance criteria determining step, wherein the at least one binocular performance criterion is selected among one or a combination of the following criteria groups consisting of central vision criteria group and/or peripheral vision criteria group.

Method for determining binocular performance of a pair of spectacle lenses

A method cuts a patch to be applied onto a curved substrate and includes the preliminary calculation of curvilinear lengths on the substrate between a reference point and a peripheral edge of said substrate. The calculated lengths are applied to a planar film for making the patch, and then the patch is cut by connecting the ends of the applied lengths. The patch then precisely coincides with the edge of the substrate. Such a method is particularly useful for applying a functional film onto a spectacle lens, as a trimming of the lens after the film is assembled with the lens would degrade said film.

A method of determining binocular performance of a pair of spectacle lenses comprises: a eyes characteristics providing step, a pair of spectacle lenses providing step, a environment providing step, a cyclopean eye positioning step, a binocular performance criteria defining step, and a binocular performance criteria determining step, wherein the cyclopean eye position is customized.
