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.

Progressive addition lenses with adjusted image magnification

A method for designing ophthalmic lenses, including progressive addition lenses, and lenses produced by the method are provided. The method permits the direct correlation of an individual's subjective assessment of the lens' performance and the objective measure of lens performance relative to the individual. The method permits generation of lens designs based on the head and eye movement of the individual and the designing of customized lenses.

Method for designing spectacle lenses taking into account an individual's head and eye movement

The invention provides multifocal ophthalmic lenses that have zones of more than one optical power, or focal length. The lenses correct for high order optical aberrations in more than one field of gaze.

Ophthalmic lenses for high order aberration correction and processes for production of the lenses

This invention provides a contact lens comprising a front surface, a back surface, and an identifying mark, wherein said identifying mark comprises one or more holes depressed into at least one of said surfaces of said lens.

Contact lenses bearing marks

The invention provides a pair of multifocal lenses for the correction of presbyopia. The dominant eye lens has an optic zone with the distance optical power required and additional zones of either or both distance and near optical power. The non-dominant eye lens has an optic zone with the near optical power and additional zones of either or both near and distance optical power.

Multifocal ophthalmic lenses

This invention provides a contact lens comprising a front surface, a back surface and an identifying mark on at least one of said front surface and said back surface, wherein said identifying mark comprises a depressed region having a cross-section which comprises at least two intersecting concave surfaces at the bottom of said depressed region.
