Method for evaluating binocular performance of spectacle lenses, method for displaying binocular performance, and apparatus therefore

摘要

To enable evaluation of the binocular performance of spectacle lenses and display of the result of the evaluation, a method and an apparatus for evaluating and indicating the binocular performance of spectacle lenses. Binocular performance indexes indicating the binocular performance of the spectacle lenses to an object point within a visual field when it is observed through specific positions on both lenses are defined. For all object points in the visual field, the binocular performance indexes are derived. An image of the visual field, in which each pixel is assigned a monochromatic luminosity or a set of primary RGB color luminosity according to the value of the binocular performance index for viewing the corresponding object point, is created and displayed.
