An optical lens intended to be worn in front of an eye of a wearer having at least one prescribed refractive power Px, the optical lens comprising two opposite optical faces and a plurality of contiguous optical elements at least part of the optical elements having an optical function of not focusing an image on the retina of the eye of the wearer so as to slow down the progression of the abnormal refraction of the eye, wherein: —over a pupil having at least a 4 mm diameter, one can measure in a plane corresponding to the at least one prescribed refractive power along at least one direction, a Modulation Transfer Function through the optical lens greater than 0.1 between 0 and 20 cyc/deg; —a majority of the light rays passing through the optical lens over said pupil pass through at least one of the plurality of optical elements, and —each of the contiguous optical element verifies that Formula (I) with d a characteristic dimension of the contour of said optical element in mm, |P| the absolute value of a characteristic optical power of said optical element expressed in diopter, and K a number greater or equal to 0.9 and smaller than or equal to 1.7.

A ophthalmic lens for inhibiting progression of myopia includes a central zone and an annular zone. The annular zone includes subsurface optical elements formed via laser-induced changes in refractive index of a material forming the annular zone. The subsurface optical elements are configured to modify distribution of light to the peripheral retina of a user so as to inhibit progression of myopia.

Systems, devices, apparatuses and methods for an active projection system that may be incorporated into spectacles, contact lenses or provided as an add-on layer to existing spectacles or lenses. The active projection system operates to generate a stimulus or stimuli for viewing by a person's eye. The stimulus or stimuli creates an image that is defocused in front of the person's retina and can assist in slowing or stopping the progression of myopia or other refractive errors in the person.

Eyeglasses are disclosed that include eyeglass frames and a pair of ophthalmic lenses mounted in the frames. The lenses include a dot pattern distributed across each lens, the dot pattern including an array of dots spaced apart by a distance of 1 mm or less, each dot having a maximum dimension of 0.3 mm or less, the dot pattern including a clear aperture free of dots having a maximum dimension of more than 1 mm, the clear aperture being aligned with a viewing axis of a wearer of the pair of eyeglasses.

The present invention relates to a novel lens unit being configured for spectral selective retinal stimulation modulation, which is advantageously a passive modulation effect in the lens of the invention. More specifically, the lens unit comprises a lens substrate having a certain volume defining a front and back surface, wherein the lens unit carries a spectral coder which, when the lens unit is in use, operates as a temporal spectral coder with respect to a portion of input light interacting with the lens unit and reaching the eye.

Provided herein is concentric annular multi-zone lens for retarding myopia progression in a human eye. The lens comprises: a plurality of correcting zones for forming a focused image on a retina of the human eye so as to correct refractive error of the human eye, wherein the correcting zone having a similar refractive power; a plurality of defocusing zones for forming images anterior to the retina so as to generate myopic defocus; and a defocusing power increasing region, in which refractive powers of defocusing zones being increasingly relatively positive towards the periphery of the lens so as to generate larger amplitude of the myopic defocus at the periphery of the retina; wherein the plurality of correcting zones and the plurality of defocusing zones are alternated in the concentric annular multi-zone lens.

A contact lens (200) having an optical axis (240) and comprising an aperture (220) on the surface (210) is disclosed. The aperture (220) is located off-center of the optical axis (240) and the aperture (220) has a central axis which is arranged such that collimated light existing the aperture (220) is directed towards a blind spot (135) at the head of an optic nerve.

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 thickness of the coating film varies over the surrounding regions of the substrate protruding portions, and technology related thereto.

A soft contact lens (4) comprises a solid component, which is based on a polymer, and a liquid component which is distributed in the solid component and which comprises at least one compound which is selected from vitamin E, vitamin B2 and the respective derivatives thereof. The contact lens has a degree of transmission of type A ultraviolet radiation greater than 50% and a degree of transmission of type B ultraviolet radiation greater than 20%.
