Systems, articles, and methods that integrate photopolymer film with eyeglass lenses are described. One or more hologram(s) may be recorded into/onto the photopolymer file to enable the lens to be used as a transparent holographic combiner in a wearable heads-up display employing an image source, such as a microdisplay or a scanning laser projector. The methods of integrating photopolymer film with eyeglass lenses include: positioning photopolymer film in a lens mold and casting the lends around the photopolymer film; sandwiching photopolymer film in between two portions of a lens' applying photopolymer film to a concave surface of a lens' and/or affixing a planar carrier (with photopolymer film thereon) to two points across a length of a concave surface of a lens. Respective lenses manufactured/adapted by each of these processes are also described.

Provided is a method for forming an ophthalmic lens as well as a lens formed by such method. The method includes the curing of a reactive monomer mixture within a mold assembly under conditions to permit incorporation of functional features into selective portions of the ophthalmic lens.

A method for producing a semi-finished spectacle lens and a semi-finished spectacle lens includes identifying the semi-finished spectacle lens by applying a removable sticker having a unique code to the semi-finished spectacle lens. The semi-finished spectacle lens has an embossed code that is engraved into the semi-finished spectacle lens. The sticker is applied to at least partially cover the embossed code. The sticker can be applied directly onto the semi-finished spectacle lens early in the manufacturing process, for example immediately after molding or injection molding. The sticker can also be applied to the semi-finished spectacle lens before further surface treatment is carried out.

Described herein are systems, devices, and methods to manufacture a feature onto the rim of an ophthalmic lens. In one embodiment, there are multiple lens rim features, and they are substantially restricted to the periphery of the lens. In alternative embodiments, the lens rim features are substantially restricted to either the top half or the bottom half of the periphery. In some embodiments, the features are added to a lens that has been finished for vision correction, whereas in other embodiments the features are added to a semi-finished lens. In one embodiment, there is a device for printing lens rim features onto an ophthalmic lens, and in another embodiment there is a system for printing such lens rim features. One embodiment is a method for printing a lens rim feature onto a lens, including the use of a device with a print-head and one or two grasping devices.

A resin amount for forming each first-stage resin layer portion (a first-stage resin replica portion) 41da in a first process is defined to be greater than a resin amount for forming each second-stage resin layer portion (a second-stage resin replica portion) 41db in a second process. Therefore, at a boundary between the first-stage resin layer portion 41da and the second-stage resin layer portion 41db, a joint portion 48 at which resin overlaps is formed, whereby occurrence of an undercut shape can be avoided. Therefore, in a molding process using a sub-master die 40 and a sub-sub-master die 50 obtained from the sub-master die 40, occurrence of an undesired shape can be avoided, whereby mold release resistance can be reduced or eliminated.

A method of manufacturing a colored contact lens including the steps of providing a transparent contact lens having a pupil section and an iris section, the iris section surrounding the pupil section and applying a colorant to the surface of the contact lens. The colorant is applied to the contact lens as an amorphous pattern and covers an effective amount of the iris section of the same. The amorphous pattern provides a lens capable of changing the apparent color of the iris of a person wearing the lens while imparting a very natural appearance.

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.

A method for producing a molding mold for use in the production of a spectacle lens in which a minute protrusion is formed on one surface thereof includes preparing a master mold that has a base material and a coating portion coating the base material and having a surface formed into a shape corresponding to the shape of the one surface of the spectacle lens; cutting a recess corresponding to the protrusion into the surface of the coating portion; producing a transfer mold by performing electroforming on the coating portion in which the recess has been cut, the transfer mold having a surface that is complementary to the surface of the coating portion; and producing a first mold by performing electroforming on the surface of the transfer mold, the first mold having a surface that is complementary to the surface of the transfer mold.

A method for producing a spectacle lens 2 including a base portion 2 that is made of a resin material and includes a convex object-side face and a concave eyeball-side face, and an optical element 12 that is made of a material different from the material for forming the base portion and is embedded in the base portion, is described. The method includes: arranging an optical element in a cavity 28 of a mold including a first mold part 20 and a second mold part 24 that can be opened and closed; introducing a resin material for forming a base portion of the spectacle lens into the cavity of the mold; obtaining the spectacle lens by curing the resin material that is a resin for forming the base portion; disassembling the mold; and detaching the spectacle lens from the mold.

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.
