    摘要： Aspheric toric lens designs are disclosed which reduce the number of cylindrical axis locations required for stock keeping units in inventory by aspherizing the toric surface thereof. The present invention pertains to ophthalmic lenses, and in particular to contact lenses such as soft hydrogel contact lenses, particularly designed to fit astigmatic patients who are either non-presbyopic or presbyopic. One of the front and back surfaces of the aspheric toric lens defines a spherical surface corresponding at least to the patient's basic distance prescription Rx. The other of the front and back surfaces defines an aspheric toric curve, wherein the toric surface is constructed with aspheric radii, such that the aspheric curve desensitizes axial misalignment of the toric curve by providing an enhanced depth-of-focus. When the aspheric toric surface is on the back surface of the lens, the spherical curve on the front surface of the lens can comprise a single spherical curve corresponding to the patient's basic distance prescription Rx. When the aspheric toric curve is on the front surface of the lens, the spherical curve on the back surface of the lens can comprise a multifocus concentric annular ring spherical surface design.

    摘要： A toric lens for axis mislocation correction having optical topography on the surface/s of the lens which induces a depth of field effect on the eye and enables the axis of powers on the lens to align with those on the eye of the wearer such that it neutralises mislocation error if the lens mislocates 1 degree or more. The lens is thin enough to allow sufficient oxygen transmission therethrough to provide satisfactory morphology of the eye of a wearer. The optical topography which induces the depth of field effect comprises either aspheric topography, spline curve functions, diffractive optics using eschelets or bi-refringence optics.

    摘要： A decentered type contact lens including: an optical zone provided in a center part of the contact lens; a peripheral zone provided on an outer circumference of the optical zone; an optical center of the optical zone being set to deviate from a lens geometric center; and a circumferential direction alignment mechanism for setting a lens circumferential direction position in a worn state, the contact lens being characterized in that: a center-of-gravity deviation in relation to the lens geometric center is set for the peripheral zone, and a center-of-gravity position shift accompanying deviation of the optical center of the optical zone in relation to the lens geometric center is corrected by offset using the center-of-gravity deviation of the peripheral zone.

    摘要： A multifocal contact lens which can provide a clear view during actual use though it is impossible to neglect important phenomena such as lens eccentricity and changes in pupil diameter. Specifically a contact lens (1) with a lens curve (2) composed of near-sight curved surfaces and far-sight curved surfaces formed alternately and arranged concentrically with respect to an optical axis (10), characterized in that an optical region (7) of the lens curve (2) has, as the near-sight curved surfaces and the far-sight curved surfaces, only a first near-sight curved surface (N1) including the optical axis, a first far-sight curved surface (F1) located outside the first near-sight curved surface, a second near-sight curved surface (N2) located outside the first far-sight curved surface, and a second far-sight curved surface located outside the second near-sight curved surface.

    摘要： Concentric annular ring lens designs are disclosed for astigmatic patients, particularly lens designs which reduce the sensitivity of the patient to toric axis misalignment, thus reducing the required number of stock keeping units in inventory for a toric product. Several of the concentric annular ring lens designs comprise a multifocal concentric annular ring design on either the front or back surface and a toric curve on the reverse surface to correct for astigmatism. Alternating concentric annular rings divide the optical zone of the contact lens into regions having at least two optical powers, a first optical power corresponding to the refractive spherical component of a patient's basic prescription Rx, and a second optical power corresponding to the cylindrical power of a patient's basic prescription Rx, or a portion thereof, with an optional third intermediate optical power, such that the multifocus toric lens is rotationally desensitized because of the enhanced depth-of-field provided by the plurality of concentric annular rings. Some embodiments of the present invention have a spherical front or back surface wherein the opposite surface has a plurality of toric annular rings. Some embodiments of the present invention eliminate a toric surface, prism ballast and slab-off features, and provide spherical optical powers at the basic prescription Rx spherical power, the cylindrical power prescription Rx, and an intermediate optical power intermediate to the spherical and cylindrical optical powers.
