The invention provides a multifocal ophthalmic lens that both corrects for the wearer's refractive prescription and takes into account pupil size of a specific individual or of a population of individuals. The invention provides a lens having an optic zone having a substantially circular central zone containing over-refracted near vision power and a diameter of about 2.5 mm or less.

Pupil regulated multifocal contact lenses

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

The invention provides a progressive multifocal ophthalmic lens pair in which the dominant eye lens incorporates more distance vision correction than does the lens for the non-dominant eye.

Multifocal contact lens pairs

The invention provides methods for designing lenses useful for correcting astigmatism in which there is a progressive cylinder power. The lens of the invention permits the cylinder power to act under low luminance situations to a different extent than in higher luminance situations eliminating the need for extra toric minus power that may interefere near vision at mid range luminances while assisting distance vision at low luminance conditions.

Progressive cylinder ophthalmic lenses

This invention includes an ophthalmic lens having a convex surface and an opposite concave surface where one of said surfaces contains alternating distance and near power zones where one or more distance zones have cylinder power.

Ophthalmic lenses useful in correcting astigmatism and presbyopia

The invention provides methods for designing lenses useful for correcting presbyopia, lenses incorporating such designs and methods for producing these lenses. The lenses of the invention exhibit a better distribution of the distance and near vision powers within the multifocal zone and, thus, improved visual acuity and wearer satisfaction.

Methods for designing multifocal ophthalmic 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

A method for fitting and designing an ophthalmic lens for a presbyope that yields improved visual acuity in general, and takes into account individual fitting characteristics. More specifically, a method for fitting and designing a contact or intraocular lens which takes into account material properties of the lens by observing the &ldquo;print through&rdquo; associated with the lens as an indicator of the topography of the lens. The term &ldquo;print through&rdquo; is used to refer to any change in lens topography on the front surface of the lens as a result of changes in topography on the back surface of the lens. If a significant amount of &ldquo;print through&rdquo; is observed, this generally indicates that the multifocal function of the lens is properly being performed. In such a situation, the clinician can then adjust the add power to the desired level. If there is not a significant amount of &ldquo;print through&rdquo;, this generally indicates that the multifocal function of the lens is not properly being performed. In this latter situation, by observing the reduced &ldquo;print through&rdquo; associated with such a lens, the clinician can instead bias one lens of a lens pair for distance power and the other lens of a lens pair for near power. Alternatively, each lens of the lens pair can be biased for some combination of distance power and near power.

Method of designing and fitting multifocal lenses taking into account material properties of the lenses

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

A method for fitting and designing ophthalmic lenses that yields improved visual acuity and takes into account individual lens fitting characteristics is provided. More specifically, the method of the invention takes into account the materials properties of the lens by observing the print-through associated with the lens.

Method of designing and fitting contact lenses taking into account material properties of the 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.

Contact lenses bearing identifying marks

A design family of contact lenses includes a central area utilized for distance vision, surrounded by multiple alternating annuli of near and distance optical powers, surrounded by a peripheral distance zone. The design can also be used in intraocular lenses (IOL). The distance optical power is constant across the design family of lenses, but the near optical power increases as a subject's presbyopia increases. The design family of contact lenses can be fitted to a patient in a standard fashion by fitting both eyes to the best distance visual acuity (VA), and obtaining near acuity from the near annuli. A modified monovision method fits the patient's dominant eye with a contact lens as described having the full prescription distance power and fitting the nondominant eye with a contact lens as described having a distance optical power between the full prescription distance optical power and the near optical power. Specifically, the nondominant eye is fitted with a contact lens as described but having a distance power between 50% and 100% of the range between the prescription near and distance optical powers, biased towards the distance optical power.

Contact lenses and method of fitting contact lenses

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.

Multifocal ophthalmic lens pair

An ophthalmic lens provides a cumulative ratio of distance to near focal length that is predominantly distance correction under high illumination, nearly evenly divided under moderate illumination, and favoring again distance vision correction under low level illumination. The lens is specifically adjusted to match the patient's pupil size as a function of illumination level, in the preferred embodiment by applying pupil size parameters as a function of age. This lens has the properties of matching both the distribution of near and distance focal vision correction to the type of human activity typically undertaken in various illumination conditions, as well as matching particular lens dimensions to suit the size of the pupil as a function of illumination intensity.
