Optical body, film adhesive body, and method for manufacturing optical body
There is provided a novel, improved optical body, the micro concave-convex structure of which can be protected without the use of a protective film, a film adhesive body, and a method for manufacturing an optical body, the optical body including: an optical film, on one surface of which is formed a first micro concave-convex structure in which an average cycle of concavities and convexities is less than or equal to a visible light wavelength; and a master film that covers the first micro concave-convex structure. The master film is provided with a second micro concave-convex structure formed on a surface that faces the first micro concave-convex structure, the second micro concave-convex structure is made of a cured curing resin, and has a reverse shape of the first micro concave-convex structure, and the optical film and the master film are separable from each other.
Methods of molding intraocular lenses
Intraocular implants and methods of making intraocular implants are disclosed. The intraocular implant can include a mask adapted to increase depth of focus. The method of manufacturing the implant can include filling an annular mask-forming trough with an opaque mask material and adding an optically transmissive optic material over the opaque mask material.
Optical assembly
An optical assembly including an optical element insert molded directly onto an optical stack is provided. The optical stack includes an optical film and may include a liner with the optical film being disposed between the optical element and the liner. The liner, if included, is removable from the optical film without substantial damage to the optical film. An outermost layer of the optical film may be diffusion bonded to a major surface of the optical element.
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.
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.
Microprismatic retroreflective mold, sheet, and article and methods of manufacture thereof
An article, including a transparent sheet having a first side with a structured surface The structured surface includes microprisms thereon, the microprisms being part of a microprism array on the structured surface. Each one of the microprisms are part of adjacent pairs of the microprisms, such that for each one of the adjacent pairs: the first microprism has a first lateral face, a second lateral face, and a third lateral face, the second microprism has a first lateral face, a second lateral face, and a third lateral face, and there is a continuous surface transition with a maintenance of surface continuity between the second lateral face of the first microprism and the third lateral face of the second microprism, without the presence of a seam, ridge, gap or tooling line.
Pre-cut adhesive supports for anatomical support, pain reduction, or therapeutic treatment
An elongate strap support system for anatomical support, pain reduction, or therapeutic treatment includes a package containing a first elongate strap support and at least one additional elongate strap support. In one example, the first elongate strap support includes a woven fabric support layer including synthetic fibers. The woven fabric is shaped so as to form an elongated strap with rounded portions. The woven fabric is substantially resistant to stretching in one direction under such test conditions as those specified in ASTM D3759. The first elongate strap support additionally includes an adhesive layer on the support layer for adhesive attachment of the woven fabric support layer to an outer skin surface of a body and a removable cover layer on the adhesive layer.
Accommodating intraocular lens
An intraocular lens (IOL) for implantation within a capsular bag of a patient's eye comprises an optical structure and a haptic structure. The optical structure comprises a planar member, a plano convex member, and a fluid optical element defined between the planar member and the plano convex member. The fluid optical element has an optical power. The haptic structure couples the planar member and the plano convex member together at a peripheral portion of the optical structure. The haptic structure comprises a fluid reservoir in fluid communication with the fluid optical element and a peripheral structure for interfacing to the lens capsule. Shape changes of the lens capsule cause one or more of volume or shape changes to the fluid optical element in correspondence to deformations in the planar member to modify the optical power of the fluid optical element.
Ophthalmic lenses for treating myopia
Eyeglasses are disclosed that include eyeglass frames and a pair of ophthalmic lenses mounted in the frames. The lenses include a dot pattern distributed across each lens, the dot pattern including an array of dots spaced apart by a distance of 1 mm or less, each dot having a maximum dimension of 0.3 mm or less, the dot pattern including a clear aperture free of dots having a maximum dimension of more than 1 mm, the clear aperture being aligned with a viewing axis of a wearer of the pair of eyeglasses.
Systems and methods for printing of 3D models
There is provided a method of representing a three dimensional (3D) object using univariate curves, comprising: receiving an initial definition of a 3D object representation, calculate a covering set of univariate curves, the covering set comprising at least one non-planar univariate curve, wherein the covering set of univariate curves represent the volume of the 3D object within a tolerance requirement, and generating a representation of the 3D object based on the set of univariate curves, wherein the set of univariate curves represent the volume of the 3D object.
