摘要: A pair of ophthalmic lenses both containing at least two optical powers, one for near vision and one for distance vision are described, both containing in the center portion of the lens the distance optical power. In the preferred embodiment, the remainder of the lens is comprised of annular portions made up of one or more optical zones to provide the desired combined, cumulative ratio of near and distance focal length areas at each pupil diameter. The distance portion located in the center is appropriately suited to the real world situation of requiring distance vision under high illumination situations.

摘要: The invention provides a method for increasing the magnification of a lens without changing the dioptric power. The method of the invention uses a measurement or an estimate of an individual's retinal function in designing the lens to provide the magnification needed by the individual without increasing the dioptric power of the individual's lens.
