Patent number: 6802607Abstract: 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.Type: GrantFiled: October 31, 2002Date of Patent: October 12, 2004Assignee: Johnson & Johnson Vision Care, Inc.Inventors: Jeffrey H. Roffman, Ganesh Kumar, Timothy R. Poling

Patent number: 6196685Abstract: 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.Type: GrantFiled: April 2, 1999Date of Patent: March 6, 2001Assignee: Johnson & Johnson Vision Care, Inc.Inventors: Jeffrey H. Roffman, Timothy R. Poling, Denwood F. Ross, III, James A. Ebel

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.Type: GrantFiled: April 21, 1999Date of Patent: January 30, 2001Assignee: Johnson & Johnson Vision Products, Inc.Inventors: Jeffrey H.

Patent number: 5835192Abstract: 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.Type: GrantFiled: December 21, 1995Date of Patent: November 10, 1998Assignee: Johnson & Johnson Vision Products, Inc.Inventors: Jeffrey H. Roffman, Edgar V. Menezes, Yulin X. Lewis, Timothy R. Poling, Michel Guillon

Patent number: 5485228Abstract: 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.Type: GrantFiled: May 20, 1994Date of Patent: January 16, 1996Assignee: Johnson & Johnson Vision Products, Inc.Inventors: Jeffrey H. Roffman, Timothy R. Poling, Michel Guillon, Edgar V. Menezes

Patent number: 5448312Abstract: 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.Type: GrantFiled: December 9, 1992Date of Patent: September 5, 1995Assignee: Johnson & Johnson Vision Products, Inc.Inventors: Jeffrey H. Roffman, Timothy R. Poling, Michel Guillon
