PROGRESSIVE LENS

摘要

A progressive ophthalmic lens including a far vision zone, a near vision zon e and an intermediate vision zone is provided having a relatively high, relatively wide near vision zone and a relatively wide intermediate zone. A surface correction(s) for reducing optical aberrations in peripheral regions of the lens may be provided within a pair of generally horizontally disposed opposed segments approximately .plusmn.22.5~ above and below a generally horizontal axis passing through a fitting cross. Two or more progressive ophthalmic lenses differing in prescribed addition power may be placed in series to provide a range of distance prescriptions for one or more of emmetropes, hyperopes and myopes. A method of designing the progressive ophthalmic lens is also disclosed.
