The present invention refers to a printed three-dimensional optical component built up from layers of printing ink characterized in that the three-dimensional optical component comprises at least one foil between two consecutive layers. The present invention further relates to a corresponding manufacturing method.

An intraocular lens configured to provide an extended depth-of-field. The lens includes a virtual aperture, the virtual aperture that includes a plurality of hexagonal micro-structures. A first plurality of light rays incident on an anterior optical surface passes through an optical zone to form an image on a retina when the intraocular lens is implanted in an eye. A second plurality of light rays incident on an anterior virtual aperture surface are dispersed widely downstream from the intraocular lens towards and across the retina, such that the image comprises the extended depth-of-field.

A method for determining an ophthalmic lens (1) for a wearer with a personalized light-filter pattern (3) defined by pattern parameters, wherein the method comprises collecting data relating to the wearer and determining the pattern parameters based on the data relating to the wearer.

A spectacle ophthalmic lens mountable on a spectacle frame, the ophthalmic lens including: a fitting cross where the optical power is negative; a first zone extending in a temporal side of the fitting cross, wherein in the first zone when the ophthalmic lens is mounted on the spectacle frame, the optical power increases when a gazing direction moves towards the temporal side, and wherein over a nasal side of the fitting cross, the optical power of the ophthalmic lens is substantially same as at the fitting cross.

An ophthalmic article and methods of manufacturing the ophthalmic article are described herein. The ophthalmic article can include a first coating and a second coating. The first coating can include an abrasion resistant coating that includes flexible materials. The abrasion resistant coating can be radiation cured. The second coating can include a sputter-applied anti-reflective (AR) coating. Such an ophthalmic article can have a Bayer value of at or between 1.25 and 2.6, between 1.25 and 2.0 or 1.25 and 1.75; and a hand steel wool value of 3 or less.

Systems and methods for controlling an ophthalmic lens edging machine are disclosed. The ophthalmic lens edging machine uses an edger code to select a macro or speed for a requested lens edging job. A system for creating and using the edger code may include a Lab Management System (LMS), a lens calculation system, and a lens edging machine. An edger code may be generated using lens data received from a lens management system and edging machine information identifying one or target lens edging machines. The edger code comprises a plurality of characters. Each character is associated with a different feature of a requested edging job. The features of the requested edging job may include, for example, one or more of: a material type, a lens thickness, an edge type, a frame type, a lens coating, a lens shape, a lens ratio, a lens treatment, and an edging machine block type.

A technology concerning a pair of spectacle lenses for binocular vision. In each of the pair of spectacle lenses for binocular vision, when an inner horizontal direction of each of the spectacle lenses is a direction toward the nose of a user who wears the spectacle lenses, and an outer horizontal direction of the spectacle lenses is a direction toward an ear of the user, a portion for viewing an object at finite distance is provided in each of the pair of spectacle lenses for binocular vision and a shape of a base in prism is formed in the position such that a line of sight of a user viewing an object through the portion is directed to a direction that is different from a direction from the object.

A method of assembling an adjustable fluid-filled lens assembly comprising biaxially tensioning an elastomeric membrane to a surface tension of greater than 180 N/m, typically greater than 1000 N/m; thermally conditioning the tensioned membrane, e.g., for one hour at a temperature of about 80° C., to accelerate relaxation of the membrane; mounting the membrane to a peripheral support structure whilst maintaining the tension in the membrane; assembling the mounted membrane with one or more other components to form an enclosure with the membrane forming one wall of the enclosure; and thereafter filling the enclosure with a fluid. The membrane may be formed from an aromatic polyurethane, and the fluid may be a phenylated siloxane. In some embodiments, the membrane is able to hold a substantially constant surface tension of at least 180 N/m for a period of at least 12 months.

Disclosed are hydrophobic, acrylic materials having both high refractive index and a high Abbe number. The materials may have an internal wetting agent, are well suited for use as implantable ophthalmic devices, and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.
