Disclosed is a multi-ring multi-focal-length single-ring inner wavy lens. The lens comprises a main lens area and a concentric circular ring area. The concentric circular ring area comprises a plurality of circular rings, the plurality of circular rings are concentrically distributed with the center of the lens as the center, the width of an annulus between every two adjacent circular rings gradually increases from inside to outside, and the circular rings each are of a wavy structure. Each wavy structure comprises peaks and valleys, the diopter of a position where each peak is located is greater than that of the main lens area, and the diopter of a position where each valley is located is smaller than that of the main lens area. The lens disclosed by the present disclosure can provide a plurality of focus regions to enhance the fitness of human eyes.

A contact lens product includes a multifocal contact lens and a buffer solution. The multifocal contact lens includes a central region and at least one annular region. The annular region concentrically surrounds the central region. A diopter of the annular region is different from a diopter of the central region. The multifocal contact lens is immersed in the buffer solution, and the buffer solution includes a cycloplegic agent.

The present disclosure relates to use of single vision ophthalmic lenses for correction of myopia in a wearer, wherein the single vision ophthalmic lens devices are configured with a base prescription to correct the myopia of the individual and are purposefully further configured with non-refractive features, wherein the non-refractive features facilitate an increase in the retinal ganglion cell activity for the wearer, which may serve as an optical stop signal to decelerate, ameliorate, control, inhibit, or reduce, the rate of myopia progression of the wearer.

Provided are an eyeglass lens that includes a lens substrate having a plurality of substrate protruding portions that protrude from a substrate base portion on a surface of the lens substrate and a coating film provided so as to cover the plurality of substrate protruding portions, the outermost surface of the eyeglass lens having a plurality of convex portions and concave portions, in which the eyeglass lens has a stray light ratio of 30% or less, and technology related thereto.

An ophthalmic lens (112′, 200) for use in preventing or slowing the development or progression of myopia comprises an optic zone (202) for focusing light from distant point objects to a focal surface. The optic zone comprises a diffractive lens (206) for manipulating the longitudinal chromatic aberration properties of the light proximate the focal surface.

An ophthalmic lens system for reducing the risk of progression of a myopic eye by selectively maintaining, inducing or creating asymmetry of the peripheral retinal profile for the eye. A method for reducing the risk of progression of myopia comprising determining the magnitude of asymmetry of the on-axis/off-axis refractive error profile or eye length profile of the eye and providing an ophthalmic lens system that corrects for and provides acceptable on-axis vision and simultaneously controls the position of the off-axis refractive error profile or eye length profile such that resultant profile of the eye is asymmetric.

The present invention provides an eyeglass lens and its related techniques, the eyeglass lens including: a base region that causes a luminous flux that has entered from an object-side face to exit from an eyeball-side face, and to enter an eye and converge on a retina; and a plurality of defocus regions that are in contact with the base region and that are each configured such that a luminous flux that passes through at least a part of the corresponding defocus region enters the retina as diverging light, in which a defocus spot angle (DSA) of the luminous flux that causes a light spot having a size mainly for cones is set in a defocus region located near the center of the eyeglass lens, and a defocus spot angle (DSA) of the luminous flux that causes a light spot having a size mainly for rods is set in a defocus region located near the periphery of the eyeglass lens.

A contact lens, which can be any of a conventional rigid contact lens, an orthokeratology lens, a scleral lens or a soft contact lens, which has one or more peripheral annular zones adjacent to and radially outward from a central optical zone of the contact lens. The peripheral annular zones include an alignment zone for orientation control, upright control or peripheral alignment to improve the molding effect of an orthokeratology lens, a comfort or vision quality of a regular RGP, scleral contact lens or soft contact lens. The sagittal height of the lens in the alignment zone along a sub-axis differs from the sagittal height of the lens along at least one other sub-axis.

A contact lens (201) includes an optic zone (202) that is centred on an optical axis (219), and a peripheral zone (204) surrounds the optic zone (202). A cross-sectional slice through the optic zone (202) along a meridian comprises a series of successive arcs (203a-203h) having a radial curvature power profile. The radial curvature power profile increases monotonically with radial distance from the optical axis (219). Light rays from a distant point source passing through the midpoint of each arc converge toward a point (215) on the first optical axis (203a-203h). For each arc (203a-203h), light rays from a distant point source pass through that arc (203a-203h) and converge towards a point (216) that is spaced away from the optical axis by a first distance. Methods of designing and manufacturing such contact lenses (201) are also described.

Provided is an eyeglass lens 1 configured to cause rays that have entered from an object-side surface 3 to be emitted from an eyeball-side surface 4, and cause the emitted rays to converge at a predetermined position A. The eyeglass lens 1 includes a lens substrate 2 having a plurality of substrate convex portions 6 on at least one of the object-side surface 3 and the eyeball-side surface 4, and a coating film covering the surface provided with the substrate convex portions 6. The shape of convex portions present on the outermost surface of the eyeglass lens located on a side on which the substrate convex portions 6 are provided is an approximate shape of the substrate convex portions configured to cause rays that have entered the eyeglass lens 1 to converge at a position B that is closer to the object than the predetermined position A is.
