Patent ID: 7753521

Claim:
An ophthalmic lens pair, comprising a first lens for a dominant eye and a second lens for a non-dominant eye of an individual, said lens pair providing distance and near vision correction and satisfying the following relationships: D ≧− 0.14 ×Rx _add+0.84 N ≧− 0.08 ×Rx _add+0.64 Δ d≦0.2 Δ n≦0.2 wherein D is a mean value of a binocular weighted distance ratio for pupil diameters of about 2.5 to 6 mm; Rx_add is an additional power in diopters added to a distance prescription to provide near vision correction for an individual; N is a mean value of a binocular weighted near ratio for pupil diameters of about 2.5 to 6 mm; Δ d is a mean value for a disparity at distance vision between the first and second lens for pupil diameters of about 2.5 to 6 mm; and Δ n is a mean value for a disparity at near vision between the first and second lens for pupil diameters of about 3.5 to about 6 mm.
