Patent number: 12130503Abstract: A soft contact lens that includes a dome-shaped flexible sheet of material. The dome-shaped flexible sheet of material includes: (a) a non-optic zone comprising the periphery of the dome-shaped flexible sheet of material, and including: an upper peripheral zone comprising an upper part of the periphery of the dome-shaped flexible sheet of material, and a lower peripheral zone comprising a lower part of the periphery of the dome-shaped flexible sheet of material. The curvature of the dome-shaped flexible sheet of material is dynamically adaptable, by virtue of at least one of the upper and lower peripheral zones being structured to laterally expand and contract; and (b) an optic zone disposed in an area of the dome-shaped flexible sheet of material that lies between the upper and lower peripheral zones, wherein the optic zone is configured to align with a visual axis of the eye.Type: GrantFiled: December 5, 2018Date of Patent: October 29, 2024Assignee: HANITA LENSES LTD.Inventor: Menachem Porat

Patent number: 5483304Abstract: A multifocal contact lens, having a rear surface configured to float on a tear film covering the user's cornea, a front surface comprised of at least two contiguous surface segments, an upper surface segment optically configured to serve for distance vision and a lower surface segment optically configured to serve for near vision. In at least one peripheral zone of the lens there is provided at least one recess constituting a preferred escape aperture for parts of the tear film displaced when the contact lens slides down the user's cornea, to the effect of substantially preventing rotation of the contact tens during lens translation.Type: GrantFiled: August 4, 1993Date of Patent: January 9, 1996Assignee: Hanita LensesInventor: Menachem Porat

Patent number: 4765728Abstract: A contact lens having a back surface comprising a central zone and at least one marginal zone. The central zone and the marginal zone being each constituted by portions of second-order surfaces of revolution other than spherical. The transition from the central to the marginal zone is tangential, and in the marginal zone, the axial clearance between the cornea and the back surface increases in direction towards the edge of the lens.Type: GrantFiled: March 11, 1986Date of Patent: August 23, 1988Assignee: Hanita Lenses, a Limited PartnershipInventors: Menachem Porat, Ofer Rabinovich
