  • Patent number: 12498589
    Abstract: Described herein are soft contact lens sets and methods of designing soft contact lens sets based on incorporating different levels of spherical aberration into the lens design depending on the target spherical power. The different levels of spherical aberration are equal to or less than zero D/mm2, and account for clinically measured population-average ocular spherical aberration, manufacturing variations and generalized accommodative ability.

  • Publication number: 20250102831
    Abstract: Fitting methods for astigmatic contact lens sets that include apodized single vision lenses for lower cylinder error correction and toric lenses for higher cylinder error correction, and related astigmatic contact lens sets. An astigmatic eye with cylinder error greater than a higher designated cylinder error label power (e.g., >1.25 diopter (D)) can be fitted with a non-apodization toric lens that has a stabilization mechanism. However, an astigmatic eye with a cylinder error up to the higher designated cylinder error label power (e.g., <=1.25 diopter (D)) can be fitted with an apodized single-vision lens. The apodized single-vision lenses have an apodization profile that reduces aberrations to provide improved vision such that a larger number of astigmatic patients up to a higher cylinder error may find vision with an apodized single-vision lens acceptable, and with enhanced comfort that comes from not having a stabilization mechanism.

  • Publication number: 20240210735
    Abstract: An ophthalmic lens for slowing or preventing the progression of myopia having a lens center, a shape defined by a lens outer peripheral edge, and an optic zone surrounding lens center and having an outer periphery. The optic zone has a central optic zone surrounding the lens center and defined by a central optic zone radius, and a peripheral optic zone surrounding the central optic zone and extending to the optic zone outer periphery. The lens includes a plurality of myopic defocus zones each positioned at a predetermined radial distance from the lens center, and each introducing a predetermined ADD power that increases with increased radial distance from lens center up to a radius of at least 4 mm. At least a first myopic defocus zone is positioned within the central optic zone, and at least first and second myopic defocus zones are positioned in the peripheral optic zone.

  • Publication number: 20240210731
    Abstract: Enhanced-summation contact lens pair for correction of presbyopia, and related enhanced-summation contact lens pairs systems and fitting methods. The optical zones of the enhanced-summation contact lens pairs are optimized as a binocular system such that a lens wearer experiences enhanced presbyopia-corrected near-distance vision like that of near monovision, but also with enhanced intermediate-distance and far-distance vision. Enhanced presbyopia-corrected near-distance vision is achieved through a center-near optical zone of the center-near non-dominant eye lens, have an add power and being optimized in diameter size based anticipated pupil miosis. Enhanced intermediate-distance vision by transitional optical zones in the enhanced-summation contact lens pair emulating an extended depth-of-focus (EDOF) through binocular summation and multi-focality when the wearer is focused on intermediate-distance objects.

  • Publication number: 20240210729
    Abstract: An ophthalmic lens and system for designing a lens. The lens includes a lens center, and a shape defined by a lens outer peripheral edge. An optic zone surrounds the lens center and has an optic zone outer periphery with an optical power selected to correct a myopic condition of a user. The lens has a toric power at the lens center that is less than a toric power at the optic zone outer periphery, and has a variable toric power that increases radially across at least a portion of the lens to at least the optic zone outer periphery. The variable toric power has a predetermined power profile that induces positive field-of-view averaged blur anisotropy for the user at or in front of a retinal plane of the user.
