Non-progressive multi-focal lens with large near/intermediate area

机译:渐近/大面积非渐进多焦点镜片

摘要

A non-progressive ophthalmic lens used in eye frames is provided with at least two and preferably only two distinct areas of prescription. A very large lower area (lower relative to the face and eyes of the wearer) is provided with intermediate or near distance vision correction prescription. A smaller, top portion of the lens is provided with a stable power, containing the wearer's prescription (or non-prescription of zero power) for distance vision correction. The two powers preferably meet at a lined intersection to conserve space that would be consumed by a progressive joining or blending of the two powers.
