MULTIFOCAL CONTACT LENSES AND METHODS FOR IMPROVING VISION AND FOR PRODUCING MULTIFOCAL CONTACT LENSES.

摘要

Pairs of multifocal contact lenses are described. Each contact lens of the pair includes a central area that provides substantially all of the distance vision correction of the lens, and an annular area surrounding the central area and providing intermediate vision correction and near vision correction. A pair of contact lenses can be used to correct a person's vision, especially presbyopia of an emerging presbyopic patient. Methods of producing the present pairs of contact lenses are also described.
