An ophthalmic lens treatment planning System receives lens and ophthalmic lens treatment information from a customer lens order, identification of available equipment to apply ophthalmic lens treatment(s) from the customer order, and performance and parameters of the available equipment. The ophthalmic lens treatment planning System formulates an optimal ophthalmic lens treatment plan to be implemented by the available equipment to apply the ophthalmic lens treatment(s) from the customer order to the lens. Following application of the optimal ophthalmic lens treatment plan to the lens, the resulting lens may be measured to provide last run results and the last run results may be fed back to the ophthalmic lens treatment planning System to provide further performance and parameters of the available equipment to the ophthalmic lens treatment planning System.

PAD TRANSFER PRINTING METHOD FOR MAKING COLORED CONTACT LENSES

The invention relates to a pad printing instrument comprising an ink supply system capable of control the temperature, viscosity and colorant concentration of an ink in an ink cup. Such controls are achieved by continuously adding and mixing a cold ink having a composition identical to the ink in the ink cup but having a lower temperature. The continuous addition of a small amount of a cold ink into the ink cup could compensate heat generated by the friction between the ink cup and a cliché and could minimize the evaporation of a diluent in the ink and change in the concentration of colorants in the ink and ink viscosity. The invention also relates to use of a pad printing instrument comprising an ink supply system of the invention for producing colored hydrogel or silicone hydrogel contact lenses.

A method for manufacturing one-piece corrective eyewear. The method includes a first step wherein an item with essentially flat blank shape is formed by a 3D-printing process. The item encompasses two lens portions, a bridge portion, and two temple portions; or the two lens portions and the bridge portion. The method includes a second step wherein the item is deformed into a wearable shape. During the first step a frame portion surrounding the lens portions is formed as part of the blank shape.

Cast Lens

An ophthalmic lens incorporating an optically functional wafer having improved adhesion to a polymerized polyurea-urethane bulk lens resin.

METHODS AND APPARATUS FOR CLEANING BLOCKED OPHTHALMIC LENSES
20170276568 · 2017-09-28 ·

A blocked lens assembly suitable for on-block processing and cleaning includes a blocked lens and a sealing member disposed on at least a portion of an edge and/or surface defined by the blocked lens. The blocked lens further includes a lens blank having a front surface and a back surface, a lens blocking piece to hold the lens blank while processing the back surface of the lens blank, and an adhesive layer, disposed between the front surface of the lens blank and the lens blocking piece, to affix the lens blank to the lens blocking piece. The sealing member protects the blocked lens so as to facilitate cleaning of the blocked lens while the lens blocking piece is affixed to the front surface of the lens blank

COLORED CONTACT LENS BASED ON AMORPHOUS IMAGES
20170248803 · 2017-08-31 ·

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.

Stabilized thin lens

A thin ophthalmic lens stabilized through incorporation of flange around all or a portion of a perimeter of the thin lens.

Lift-off method by means of jetting
11198265 · 2021-12-14 · ·

A method for structured coating of a surface of a substrate. The surface includes spaced optical elements and at least partially metallic elements provided adjacent the optical elements. After the application of the method, the optical elements should be completely covered with the coating, whereas at least some of the metallic elements should not be coated on the major part of their surface. The method includes: a) providing the substrate with the spaced optical elements and metallic elements; b) applying a sacrificial material to at least some of the metallic elements to form sacrificial spots; c) coating the surface of the substrate with a layer system; and d) detaching the sacrificial spots from the substrate, wherein the regions of the layer system on the sacrificial spots are also detached from the substrate. The application of the sacrificial material is carried out at least partially by jetting.
