Optical adhesive and optical laminates and lenses formed with same
The present invention pertains to polyurethane-urea based optical adhesives for formation of optical film laminates, optically functional film laminates, and ophthalmic or eyeglass lenses employing the same and methods for producing the same.
GLASSES MANUFACTURE
A method of eyewear manufacture including: adhering frame material onto a surface of a corrective lens, the frame material extending along at least 10% of an edge circumference of the lens; and attaching the lens to a second lens
EYEWEAR LENS CREATION USING ADDITIVE TECHNIQUES WITH DIFFUSE LIGHT
Systems and methods for lens creations are disclosed. The method includes initiating light transmission from a light source through a diffuser into a container holding resin and a substrate. The light transmission is performed according to an irradiation pattern wherein each point in the resin is illuminated by at least 10% of the diffuser. This causes a lens to be formed. To achieve this illumination, at least 15% of the diffuser receives light from the light source. Further, a diameter of the diffuser is greater than or equal to a diameter of the substrate. The system performing the methods includes a polymerization apparatus and may include a resin conditioning and reservoir apparatus, a metrology unit, a resin drainage apparatus and an optional postcuring apparatus.
Method for mounting functional elements in a lens
A method for mounting functional elements in a lens includes mounting the functional elements on a foil, applying a closed contour alignment surface of an alignment tool having a central opening surrounded by the closed contour on the foil portion opposite to the mounted function elements, applying underpressure on the central opening to maintain the foil portion with the mounted functional elements on the alignment tool, cutting a flap including the foil portion and supporting the functional elements out of the foil, positioning and aligning the flap through actuator, fixing the position of the flap against the adjacent foil surface, embedding the foil with the mounted functional elements in a predetermined distance to the front surface of a mould, and casting and curing the lens with the embedded foil.
Small diameter corneal inlays
Methods of manufacturing and implanting corneal inlays, such as small diameter corneal inlays, are provided. The methods include manufacturing an implant body to have a meniscus shape with a small diameter and an index of refraction, and implanting the implant body in a corneal bed of a cornea. The inlays cause a change in an anterior surface of the cornea after implantation due to the implant body.
Methods of manufacturing liquid lenses
A method of forming a liquid lens, comprising the steps of: positioning a first substrate defining a hole over a second substrate, wherein a cavity is defined within the second substrate and aligned with the hole; dispensing a second liquid into the cavity defined within the second substrate; capping the second liquid with a first liquid dispensed through the hole, wherein the first liquid and the second liquid have different refractive indices than each other; and translating at least one of the first substrate and the second substrate such that the hole is not aligned with the cavity.
Configurable fixture for cutting shapes
A fixture used in the manufacture of an eyepiece, to cut the eyepiece to a particular shape, and a method of using the fixture to cut the eyepiece to have a desired shape. Embodiments are directed to a configurable fixture to align, hold, and protect a plastic sheet (e.g., a wafer) while a laser cutting apparatus is cutting one or more eyepieces out of the wafer. During the cutting, the fixture protects the eyepieces from reflected laser light by providing voids around the laser cutting lines, and by supporting each eyepiece near its perimeter. The fixture can be quickly rearranged for different eyepieces, different eyepiece shapes, and/or different plastic sheet sizes.
Apparatuses and methods for actuation of optical elements
An apparatus having an asymmetric adjustable lens with a deformable optical element. The apparatus may also include one or more actuators coupled to a deformable element of the asymmetric adjustable lens in a direct-drive configuration such that (1) mechanical action of the one or more actuators applies force to the deformable optical element and (2) the force applied by the mechanical action of the one or more actuators changes an optical property of the asymmetric adjustable lens by deforming the deformable optical element. Various other devices, systems, and methods are also disclosed.
Method of forming and incorporating a polymeric lens within a lens housing
A method for forming a lens housing containing a polymeric lens including inserting a mandrel having a distal face with negative features of the desired polymeric lens into a cylinder and filling a reservoir formed between the distal face and a distal end of the cylinder with a curable polymeric lens material. The curable polymeric lens material is cured in place within the reservoir thereby forming the desired polymeric lens. The proximal surface of the polymeric lens is formed and shaped by the distal face of the mandrel, while the distal surface of the polymeric lens is dependent upon the amount of the curable polymeric lens material placed in the reservoir and the volume of the reservoir.
Spectacle lens and method for producing same
A spectacle lens includes a first volume element group containing a plurality of first volume elements. The plurality of first volume elements is made from a material with a first Abbe number in the form of grid points of a geometric grid. Further, the spectacle lens includes a second volume group containing a plurality of second volume elements, which form a second partial grid in the form of grid points of a geometric grid, the second volume elements being made of a second material having a second Abbe number, wherein the first Abbe number and the second Abbe number differ from each other. The first partial grid and the second partial grid are arranged offset from each other. The disclosure also relates to a corresponding computer-implemented method for designing a spectacle lens of the type and to a method for producing the type of spectacle lens.
