Abstract: Curved lenses configured to decode three dimensional content and method of fabricating the same. The lenses decode three-dimensional content displayed on televisions or computer monitors. Sheets from which the lenses are cut have either (i) a polarizing axis of 0 degrees relative to horizontal and one sheet has a retarder axis at ?45 degrees relative to horizontal and the other sheet has a retarder axis of +45 degrees relative to horizontal; (ii) a polarizing axis of ?45 degrees relative to horizontal and one sheet has a retarder axis at 0 degrees relative to horizontal and the other sheet has a retarder axis of 90 degrees relative to horizontal; or (iii) a polarizing axis of +45 degrees relative to horizontal and one sheet has a retarder axis at 0 degrees relative to horizontal and the other sheet has a retarder axis of 90 degrees relative to horizontal.

Abstract: Azo compounds that block visible light are disclosed. These light absorbers are particularly suitable for use in intraocular lens materials.

Abstract: The invention relates to an optical article including a transparent substrate of organic glass, preferably a substrate of an ophthalmic lens, an adhesive layer covering at least one of the faces of the transparent substrate, a transparent film of thermoplastic polymer fixed on the transparent substrate by means of the adhesive layer, an anti-abrasion hard coating covering the transparent film of thermoplastic polymer, and a multilayer antireflection coating formed from alternating mineral layers with high and low refractive index. The invention also relates to a method of manufacturing said article.

Abstract: This invention provides for an ophthalmic lens with at least one portion of the lens including multiple voxels of polymerized crosslinkable material. In addition, the present invention provides for apparatus for generating an ophthalmic lens with one or more areas of different refractive indexes and a surface with one or both of a raised area and a depressed area.

Abstract: The invention provides to methods for diagnosing eye-length related disorders, including myopia. The invention also provides methods for treating and limiting eye-length related disorders, including myopia. In addition, the invention provides certain haplotypes associated with eye-length related disorders, including myopia and Bornholm Eye Disease.

Abstract: A variable focus lens system for eyeglasses is disclosed. The system consists of superimposed first and second thin lenses, simulating Alvarez lenses, with one side of each lens divided into Fresnel zones and zone boundaries. The second lens element is slidable for focus adjustment. The Fresnel zone boundary surfaces are made parallel to the user's optical line of sight to reduce visual obstructions, and the zone boundaries may be restricted to areas near the lens periphery to further reduce visual obstructions. The Fresnel zone boundaries may follow paths which enable equal, constant step size for the boundaries along their lengths. An opaque light absorbing coating may be applied to the zone boundaries to reduce light scattering. A fixed prescription lens, having the user's distance and astigmatism corrections, is superimposed on the first and second lens elements.

Abstract: The invention relates to a vision screen having a continuous convex surface (2) that is cylindrical, toroidal, or spherical, and that presents a trace in a binocular plane of sight that forms an outer circular arc of determined radius (R), the vision screen having a concave surface presenting a trace in the same plane of sight that forms, at least in a region around a point of intersection of each line of sight (AD, AG) with the concave surface, an inner circular arc (3, 4) having a specific radius of curvature (R1), and having a center (C1, C2) that is different from the center of the circular arc intersected by the other line of sight, wherein the radius (R1) specific to each inner circular arc is different from the radius (R) of the outer circular arc.

Abstract: The present invention relates to ophthalmic systems and coatings comprising a selective light wavelength filter, wherein said selective filter provides improved contrast sensitivity.
