Abstract
Official abstract text for this publication.
A family of ophthalmic lenses for correcting presbyopia meets constraints for distance vision, near vision, and disparity and may be designed according to a process that incorporates a merit function accounting for binocular visual performance.
First claim
Opening claim text (preview).
We claim: 1. A lens pair that satisfy a predetermined set of conditions, the lens pair conditions comprising: D ≧− 1.0×ADD+0.53; N ≧− 1.40×ADD; and Δ ≦1.65×ADD−1.2, wherein D is the mean of the monocular performance of the left and right eyes averaged over pupil size ranging from 2.5 to 6.0 mm in diameter for a distant object, N is the mean of the monocular performance of the left and right eyes averaged over pupil size ranging from 2.5 to 6.0 mm in di…
