The present invention refers to a printed three-dimensional optical component built up from layers of printing ink characterized in that the three-dimensional optical component comprises at least one foil between two consecutive layers. The present invention further relates to a corresponding manufacturing method.

An intraocular lens configured to provide an extended depth-of-field. The lens includes a virtual aperture, the virtual aperture that includes a plurality of hexagonal micro-structures. A first plurality of light rays incident on an anterior optical surface passes through an optical zone to form an image on a retina when the intraocular lens is implanted in an eye. A second plurality of light rays incident on an anterior virtual aperture surface are dispersed widely downstream from the intraocular lens towards and across the retina, such that the image comprises the extended depth-of-field.

An ophthalmic article and methods of manufacturing the ophthalmic article are described herein. The ophthalmic article can include a first coating and a second coating. The first coating can include an abrasion resistant coating that includes flexible materials. The abrasion resistant coating can be radiation cured. The second coating can include a sputter-applied anti-reflective (AR) coating. Such an ophthalmic article can have a Bayer value of at or between 1.25 and 2.6, between 1.25 and 2.0 or 1.25 and 1.75; and a hand steel wool value of 3 or less.

Disclosed are hydrophobic, acrylic materials having both high refractive index and a high Abbe number. The materials may have an internal wetting agent, are well suited for use as implantable ophthalmic devices, and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.

An optical plastic product has an optical multilayer film formed on one or both surfaces of a base made of plastic, directly or via an intermediate film, wherein the optical multilayer film includes a tensile-stress high-refractive-index layer having tensile stress as internal stress and made of a high refractive index material, and a low refractive index layer made of a low refractive index material, and the tensile-stress high-refractive-index layer is disposed with a physical film thickness of not greater than 10 nm, in a first layer as counted from the base side in the optical multilayer film.

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.

A method of making an optical article having a gradient tint and a gradient polarization. The method includes providing an optical element including a coating having at least one alignment zone. A dye composition is contacted with the coating. The dye composition includes at least one of: a dichroic dye, a photochromic-dichroic dye, or a combination thereof to diffuse at least a portion of the dye composition into the coating at a predetermined concentration gradient along at least a portion of the coating to provide the gradient tint and the gradient polarization. A kit for making an optical article having a gradient tint and a gradient polarization. An optical article prepared from a method for making an optical article having a gradient tint and a gradient polarization.

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.
