摘要： A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having an anterior surface, a posterior surface, at least one diffractive structure and at least one base curvature. The at least one diffractive structure for provides a first spherical aberration for a first focus corresponding to at least a first focal length. The at least one base curvature provides a second spherical aberration for at least a second focus corresponding to at least a second focal length. The first spherical aberration and the second spherical aberration are provided such that the first focus has a first focus spherical aberration and the second focus has a second focus spherical aberration. The first focus spherical aberration is opposite in sign to the second focus spherical aberration.

摘要： Embodiments of the present disclosure describe a biomarker-responsive bifocal contact lens comprising a monovision contact lens having a first focal length and a Fresnel contact lens having a second focal length, wherein the Fresnel contact lens comprises a biomarker-responsive hydrogel, and wherein the Fresnel contact lens is disposed on an outer surface of the monovision contact lens, wherein an optical characteristic of the Fresnel contact lens changes in response to the biomarker concentration in the ocular fluid.

摘要： A contact lens for use in controlling or retarding the progression of myopia in an eye has a central optical zone approximating the normal diameter of the pupil of the eye that gives clear central vision at distance for the wearer. An annular peripheral optical zone that is substantially outside the diameter of the pupil is formed around the central optical zone with greater refractive power than that of the central zone so that oblique rays entering the eye through the peripheral optical zone will be brought to focus at a focal plane that is substantially on or anterior to the peripheral region of the retina. Preferably, the rear surface of the lens is shaped to conform to the cornea of the eye and the front surface of the lens is shaped to provide—in conjunction with the rear surface—the desired optical properties of the central and peripheral optical zones. The front surface is also preferably contoured to form a smooth transition between the junction of the central optical zone and the peripheral optical zone, with or without designed optical properties such as progressive power.

摘要： A progressive multifocal contact lens and producing method thereof are provided. The progressive multifocal contact lens includes a first optical region of a front optical surface and a second optical region of a back optical surface. The first optical region includes a center zone, an outer zone and an intermediate zone connected between the center zone and outer zone where the center zone and outer zone are selected from a distance vision power and a near vision power and the intermediate zone is configured to adjust the optical power of the distance vision power and the near vision power so that the optical power or add power of the first optical region on the front optical surface forms a normal cumulative distribution function.

摘要： The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) and associated method for their design and use. In an embodiment, an ophthalmic apparatus (e.g., a toric lens) includes one or more angularly-varying phase members comprising a diffractive or refractive structure, each varying the depths of focus of the apparatus so as to provide an extended tolerance to misalignment of the apparatus when implanted in an eye. That is, the ophthalmic apparatus establishes an extended band of operational meridian over the intended correction meridian.

摘要： A lens system for presbyopes utilizes inter-eye disparity limits to improve vision. The system of lens may be utilized to improve binocular vision when viewing distant, intermediate and near objects by requiring a minimal level of disparity in vision between the eyes wherein the level is not objectionable to the patient. This disparity in vision depends on the lens design for each eye and upon how the lenses are fit in each eye relative to the distance refraction of the patient.

摘要： A progressive multifocal ophthalmic lens includes at least three high power segments, at least three low power segments, and a plurality of progressive power segments. Shapes of the high power segments and the low power segments are sectors. The high power segments and the low power segments are disposed alternately along an arc direction of the progressive multifocal ophthalmic lens. Shapes of the progressive power segments are sectors. Two sides of each of the progressive power segments along the arc direction respectively connect one of the high power segments and one of the low power segments. The high power segments, the low power segments, and the progressive power segments form a progressive multifocal surface.
