Ophthalmic lenses and method of manufacturing ophthalmic lenses are disclosed. The lenses are manufactured with markers for aligning the lenses in a particular rotational alignment with respect to a spectacle frame. The lenses can also be provided with scattering parts for defocus to prevent myopia.

A method for fabricating one or more elements in a multi-lens column. Drops of ultraviolet (UV)-curable liquid are dispensed by an inkjet on a substrate, which may be supported by a chuck. A non-uniform liquid film is then formed, such as by spreading and merging of the inkjetted drops. The film is then locally heated, such as by using a digital micromirror device array. The film is then cured by exposing it to UV light, where the cured film together with the substrate form an element of the multi-lens column. The substrate is then brought to a metrology station where optical metrology is performed on the cured film and the substrate for quality control.

A light emitting device includes: a substrate; and at least one light-emitting part comprising a light source and a sealing member covering the light source, wherein the sealing member includes a dent and a peripheral portion surrounding the dent, and includes at least one projection at the peripheral portion.

A transfer printing apparatus includes a mold, a stamper, a pressing roller and a curing unit. The mold has a first surface with first and second concavities, the second concavity has first and second planes, the first plane is perpendicular to the first surface, and the second plane is inclined to the first surface. The stamper having a second surface is disposed in the first concavity. The first and second surfaces are coplanar, and the second surface has transfer printing microstructures. The first and second surfaces are suitable for coated an adhesive layer. The pressing roller presses a base film onto the adhesive layer, such that the adhesive layer is integrated with the base film. The curing unit cures the adhesive layer on the base film, such that a taper corresponding to the second concavity and optical microstructures corresponding to the transfer printing microstructures are formed on the adhesive layer.

Disclosed herein is an antiglare glass sheet article for display devices in which at least one main surface of the glass sheet is roughened. The article has a roughened surface that includes: a surface with continuous irregularities having an arithmetic average roughness (Ra) of 0.01 to 0.1 μm, and an average interval (RSm) of 1 to 20 μm; and depressions dispersed over the surface and each having a circular entrance portion measuring 3 to 20 μm in diameter, and a depth of 0.2 to 1.5 μm from the entrance portion, the roughened surface having 60 to 600 of the depressions in an observed 250 μm ×250 μm region. The article has desirable antiglare properties with reduced sparkling.

Provided are a method with which a spectacle lens molding mold having a minute recess can be made with high accuracy, and the like. A method for producing a molding mold 12 for molding a spectacle lens 1 in which a minute protrusion 6 is formed on at least one surface thereof includes a first molding mold preparation step of preparing a first mold 14 that includes a base material 26 and a coating portion 28, the coating portion being made of a nickel alloy, coating the base material, and having a surface formed into a shape corresponding to the shape of one surface of the spectacle lens; and a cutting step of cutting a recess 28A corresponding to the protrusion into the surface of the coating portion of the first mold.

A lens element adapted for a person including a holder including a refraction area having a refractive power based on a prescription for correcting an abnormal refraction of the person, a plurality of optical elements placed on at least one surface of the holder to at least one of: slow down, retard, or prevent a progress of the abnormal refraction of an eye of the person, and at least one layer of at least one coating element covering at least a zone of at least one optical element and at least a zone of the holder on which the optical elements are placed, wherein said at least one layer of at least one coating element adds an optical power of 0.1 diopter in absolute value in specific wearing conditions when measured over said zone of the optical element covered by said at least one layer of at least one coating element.

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.

A lens element adapted for a person including a holder including a refraction area having a refractive power based on a prescription for correcting an abnormal refraction of the person, a plurality of optical elements placed on at least one surface of the holder to at least one of: slow down, retard, or prevent a progress of the abnormal refraction of an eye of the person, and at least one layer of at least one coating element covering at least a zone of at least one optical element and at least a zone of the holder on which the optical elements are placed, wherein said at least one layer of at least one coating element adds an optical power of 0.1 diopter in absolute value in specific wearing conditions when measured over said zone of the optical element covered by said at least one layer of at least one coating element.
