METHOD OF MANUFACTURING A PAIR OF PROGRESSIVE OPHTHALMIC LENSES
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 relates to width values of far vision fields and/or proximate vision fields, for indicating that the fiel...

Summary: | 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 relates to width values of far vision fields and/or proximate vision fields, for indicating that the fields are different enough in width between both lenses. A second one of the conditions sets a maximum value for the relative difference in mean refractive power gradient between both lenses. |
