Provided is an optical component whereby the absence of eccentricity can be instantly confirmed visually even in a case that the optical component has Fresnel lens or other very fine structure. An optical component of the present invention includes an optical part and a peripheral part thereof. The optical component includes recognition marks in positions substantially plane-symmetrical to each other on a front surface side and a rear surface side of the peripheral part, the recognition marks being expressed as a recess or a projection and configured to allow eccentricity to be recognized. Two of the recognition marks are preferably similar to each other in shape, one recognition mark being preferably from 10% to 90% the size of the other recognition mark.

The present invention is a method for producing a spectacle lens from a lens material, and includes: a marking step (step S10) of marking an identification mark for identifying the spectacle lens, and a processing information mark which is used to process a lens blank and includes a tray identification 2D code, a tray identification code, a shape line and a position mark by forming a hole or a groove in a convex surface of the lens material by laser; and a concave surface machining processing step (step S13) of reading the processing information mark, and machining a concave surface of the lens blank based on the read processing information mark.

The supply systems for providing spectacle ophthalmic lenses have improved efficacy, in particular with respect to lens blank picking performance and/or lens manufacturing performance.

Disclosed herein is a lens for a wearable projection system. The lens includes a holographic optical element embedded within the lens and covering a portion of the viewable area of the lens. The lens can be manufactured by providing a first lens blank, affixing the HOE to a portion of the first lens blank, and forming a second lens blank on the first lens blank to embed the HOE between the lens blanks.

A laser patterning apparatus of a three-dimensional object to be processed, which includes a laser generation unit, a first beam adjustment unit for adjusting the magnitude of a laser beam generated in the laser generation unit, a second beam adjustment unit for adjusting the focal location of z-axis, x-axis, and y-axis of the laser beam via the first beam adjustment unit, and a control unit for controlling the second beam adjustment unit so that laser patterning is performed on a three-dimensional object to be processed.

A system and method for coating a lens (10) using a plurality of inkjet print bars (46) arranged in-line, includes generating, using at least one processor (54, 110) in communication with the plurality of inkjet print bars (46), at least one graphical user interface configured to facilitate the automation of the creation or selection of an image to be printed on a lens (10); generating a plurality of image layers based on the lens (10) geometry, target product, and number of print bars (46); and controlling, using the at least one processor (54, 110), at least two of the plurality of inkjet print bars (46) to print the image on the lens (10), such that each of the at least two inkjet print bars (46) prints at least one image layer of the plurality of image layers.

The supply systems for providing spectacle ophthalmic lenses have improved efficacy, in particular with respect to lens blank picking performance and/or lens manufacturing performance.

Optical articles and methods of manufacturing the same are disclosed herein. In one aspect, the methods and optical articles formed include light-blocking compositions applied to optical substrates in accordance with the optical properties of the optical substrate. In another aspect, a method is disclosed in which the light-absorbing compositions are printed onto the optical substrate in the shape and size of the final lens that is to be formed from the optical substrate. In another aspect, the methods and optical articles utilize at least two different light-blocking compositions to achieve desired functionality of the optical article.

Intraocular implants and methods of making intraocular implants are provided. The intraocular implants can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. In particular, the intraocular implants can include a mask having an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion such as a clear lens or aperture. This construct is adapted to provide an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The intraocular implant may have an optical power for refractive correction. The intraocular implant may be implanted in any location along the optical pathway in the eye, e.g., as an implant in the anterior or posterior chamber.

A dyeing method for functional contact lenses includes the following steps: providing a dry lens body, including hydrogel with 0-90% water content, silicone hydrogel with 0-90% water content, or a combination thereof; preparing an amphoteric polymethyl ether prepolymer, combining the amphoteric polymethyl ether prepolymer with a hydrophilic monomer to form a masking ring material, and attaching the masking ring material to an inner surface of the dry lens body to form a masking ring layer; dropping a colorant onto the inner surface, making the masking ring layer surround the colorant, irradiating the colorant with an ultraviolet light and then heating and fixing the colorant to form a dyed layer on the inner surface; and placing the dry lens body in water to hydrate and removing the masking ring layer to obtain a wet lens body.
