    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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 “print through” associated with the lens as an indicator of the topography of the lens. The term “print through” 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 “print through” 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 “print through”, this generally indicates that the multifocal function of the lens is not properly being performed. In this latter situation, by observing the reduced “print through” 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.
