Systems and methods for creating fully custom products from scratch without exclusive use of off-the-shelf or pre-specified components. A system for creating custom products includes a computer communicatively coupled with an image capture device and configured to construct an anatomic model of the user based on captured image data and/or measurement data. The computer provides a configurable product model and enables preview and automatic or user-guided customization of the product model. A display is communicatively coupled with the computer and displays the custom product model superimposed on the anatomic model or image data of the user. The computer is further configured to provide the customized product model to a manufacturer for manufacturing eyewear for the user in accordance with the customized product model.

The current invention is a detachable eyeglass frame system that will provide consumers a way to take their single pair of prescription lenses out of their manufacturers frames and place them into another set of the same manufacturer's frames but, of different color and/or style. The eyeglass frame system comprises an eyeglass frame including a front section removably secured to a horizontal bar. The horizontal bar is removably secured along the upper end of the front section by one or more fasteners, such as magnets. By lifting the Removable Horizontal Bar from Frame Rear, lenses easily slide out of their current frames and easily slide into their other frames.

A rewritable and freezable lens and method for manufacturing thereof are disclosed. This lens includes at least one active element that has optical properties that can be written, frozen and rewritten into new values at least twice. Rewritable and freezable lenses comprising active index polymer dispersed liquid crystal materials are disclosed. In-situ re-adaptation of spectacle and contact lenses is possible at the point of sale. In-vivo re-adaptation of intraocular lenses in the doctor's room is feasible, avoiding further surgery.

Disclosed is a method for manufacturing an ophthalmic lens including a substrate and a functional film securely fastened to a curved face of the substrate. This method includes a method for gluing the initially flat functional film to the curved face. To ensure that the functional film when securely fastened to the curved face filters a preset band of wavelengths centered on a wavelength denoted λp, multiple functional films are preselected; two knowledge bases are established experimentally; a film is selected, using the two knowledge bases, from the plurality of preselected films, the wavelength λi′ on which is centered the band of wavelengths that this film filters for a certain degree of deformation being equal to λp when the degree of deformation is that given for the curvature in question; and the gluing method is implemented in order to securely fasten the selected film to the curved face.

A method of manufacturing of an astigmatic contact lens having a toric portion and a thickness differential feature to provide lens orientation on eye portion such that said thickness differential causes the toric portion of the contact lens to properly orient in the eye of the wearer. The toric lenses are manufactured by an effective process control method for cylinder power in toric lens production by determining an amount of a mold cylinder compensation which is caused by processes in a toric lens manufacturing system including tool making, injection molding, casting and curing, wherein the mold cylinder is defined as the difference in measured radius of curvature at two orthogonal directions. A control metric is established by using the amount of a mold cylinder compensation and tolerance range and reject mold out of the control limits and improve the production yield for toric lens manufacturing.

A method of fabricating a lens element for an adjustable power lens of the kind comprising two lens elements that are slidable relative to one other in a direction transverse the optical axis of the lens and have respective lens surfaces that are shaped to act together to form a corrective lens, the power of which varies according to the relative disposition of the two lens elements, the method comprising the steps of forming a lens puck having two opposite faces, which are shaped to form opposite lens surfaces of one of the lens elements of the adjustable power lens, the puck having at least one alignment feature, and thereafter edging the puck to a desired eye shape with reference to the alignment feature.

A method of preparing individual spectacle lenses (L) in accordance with a prescription order comprises the steps of: (i) blocking, a provided lens blank (LR) as workpiece on a block piece provided from a plurality of block pieces (B) from a block piece store (BL), (ii) processing the blocked lens blank at least at a second surface so as to obtain a blocked, processed spectacle lens (L) as workpiece, and (iii) deblocking the processed spectacle lens from the block piece, wherein the workpiece, optionally in the blocked state, is transported between the steps (i) to (iii) in one of a plurality of provided transport boxes (T). In the method, the block pieces prior to the step (i) of blocking are stored in the transport boxes in the block piece store and, for the step (i) of blocking, are provided in the transport boxes from the block piece store.

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.

An eyeglass lens replacement assembly is revealed. A limiting slot is formed on each side of a frame and a limiting stopper is arranged in the limiting slot. A temple pivot member is mounted in the limiting slot. A lens is mounted to a lens connection portion of the frame and two sides of the lens are inserted into insertion slots of the temple pivot members. Each side of the lens is provided with a positioning dent which is locked with a positioning bulge of the insertion slot. A limiting bulge of a positioning portion pivoted on the temple pivot member is limited in a limiting notch of the lens while a locking recess of the positioning portion is locked and positioned by an inner wall surface of the insertion slot. Thereby the frame, the temple pivot members and the lens are combined with and connected to one another firmly.

Modular eyeglass frame system and methods for their use and manufacture. Exemplary frame systems include an eyeglass frame base having a top edge, a removable element having a top edge that substantially matches the top edge of the frame base, and one or more attachment elements operative to removably attach the removable element to the frame base. The frame base includes a first channel and a second channel suitable for partially enclosing a first lens and a second lens; and the removable element includes a first channel and a second channel, each removable element channel being configured such that when the removable element is attached to the frame base, the first and second channels of the frame base align with the first and second channels of the removable element to fully enclose a periphery of the first lens and the second lens. The one or more attachment elements secure the removable element to the frame base such that the two-piece frame system is substantially as durable as a solid one-piece frame.
