Aspheric Zone Patents (Class 351/159.13)
  • Patent number: 9039172
    Abstract: A method and system for treating Presbyopia and pre-Presbyopia are provided that do not compromise the wearer's intermediate or distance vision. The system is a lens and a lens series, wherein the power profiles of the lenses are tailored to provide an amount of positive ADD power in the near vision zone that is slightly less than that which is normally required for near vision accommodation, while also providing an amount of negative spherical aberration in the peripheral optical zone. The dynamic ocular factors of the wearer's eye work in conjunction with the positive ADD power provided by the central optical zone and with the effective ADD gained from the negative spherical aberration provided by the peripheral optical zone to induce a minimally discernible amount of blur that is tuned to maximize the wearer's depth of focus.

  • Publication number: 20140347622
    Abstract: A lens for correcting vision of a user includes a central zone and an outer zone. The central zone is configured to cause light passing therethrough to form an image on a retina of an eye of the user. The outer zone surrounds the central zone and has a plurality of different aspherical coefficients for respectively causing light passing therethrough to form images spaced apart from the retina.

  • Patent number: 8783863
    Abstract: This invention provides a contact lens for myopia control comprising: an object-side surface comprising a central zone, a transition zone and a peripheral zone which are concentric and have different refractive power, at least one of the three zones being aspheric; and an image-side surface; wherein the central zone provides correction power to focus a foveal image on the retina, the peripheral zone provides a myopic defocus effect by generating a para-fovea image in front of the retina, and the transition zone with one or more focuses provides a refractive power in diopter (D) ranging from +0.25 D to +8.00 D.

  • Publication number: 20130222761
    Abstract: A toric contact lens utilizes concentric annual rings, a continually varying lens design as a function of distance from the lens center or any other function to create a range of cylinder axis zones on a single lens.

  • Publication number: 20120113386
    Abstract: Contact lenses provide clear visual acuity and simultaneously present a myopic defocused image to the lens wearer at both near viewing distances and distant viewing distances. The present contact lenses have an optic zone that has a radius of less than or equal to 2.5 mm. Stated differently, the diameter of the optic zone of the present contact lenses is 5.0 mm or less. The present lenses are used in methods to reduce progression of myopia in a person capable of ocular accommodation. Methods of manufacturing the present lenses are described.
