Abstract

See full text

A pair of progressive ophthalmic lenses (1, 2) meets special conditions for improving binocular vision of a wearer, while avoiding discomfort for peripheral vision. A first one of the conditions sets a minimum value for the difference between nasal and temporal half-widths of far vision field and/or proximate vision field for at least one of the lens. A second one of the conditions sets a maximum value for the relative difference in mean refractive power gradient between both lenses.
