Abstract: A transparent covering affixable to a substrate includes a stack of two or more lenses, an adhesive layer interposed between each pair of adjacent lenses from among the two or more lenses, a first anti-reflective coating on a first outermost lens of the stack, and a second anti-reflective coating on a second outermost lens of the stack opposite the first outermost lens. The first anti-reflective coating has a first design wavelength range, and the second anti-reflective coating has a second design wavelength range that is different from the first design wavelength range.

Abstract: Eyewear for enhancing the contrast sensitivity of the human vision system through the use of lenses subdivided in areas of different light filtration properties arranged in specialized patterns, called multi-filters patterns, are provided. Of the multiple filtration areas, or filters, that compose each multi-filters patterns, one or more filters heavily reduces or totally block light arriving from some areas of the visual field of the eyes, while other filters lightly reduce or totally allow light from other areas of the same visual field. The resulting effect is to drive the auto-exposure function of the eye-brain vision system to adapt itself to areas of interest of the visual field thus improving contrast sensitivity and vision acuity in those areas while reducing or blocking light and glare from the rest of the visual field.

Abstract: The present invention is embodied in an eyewear lens with at least two controlled, limited visible light blocking filters that attenuate its transmittance spectrum. More specifically, in the present invention, the eyewear lens attenuates limited amounts of light in at least two visible wavelength regions via controlled, limited blocking filters, wherein the overall luminous transmittance is at least 75%. The at least two controlled, limited blocking filters have their peak blocking wavelengths in the region of 410-500 nm and 530-620 nm, respectively. In a preferred embodiment, the minimum transmittance that occurs within the 410-500 nm region is ?55% and the minimum transmittance that occurs within the 530-620 nm region is ?65%. In another preferred embodiment, the eyewear lens comprises an anti-reflective coating on its inner surface (the eye-side of the lens).

Abstract: A contact lens for treating binocular diplopia, the contact lens comprising: a central region adapted to degrade light passing therethrough, so as to create a central scotoma in a patient's eye in which the contact lens is placed in use; and a peripheral region adapted to degrade light passing therethrough to a lesser extent than in the central region, or not at all; such that, in use, an image in the field of view of the said eye is degraded only in the center or to a greater extent in the center than in the periphery. Also provided is a method of manufacturing such a lens, and a method of treating binocular diplopia comprising applying such a lens to a patient's eye.

Abstract: The present invention describes ophthalmic lens products comprising a multilayer wafer and an injection-molded polycarbonate inner portion. The multilayer wafer includes a dyed, photochromic or polarized layer between a tinted inner layer and an outer polymeric layer. The inner layer may be solid or gradient-tinted. The polycarbonate inner portion of the lens product is directly fused to the tinted inner layer of the multilayer wafer during injection molding. The invention further describes a method to produce a gradient-tinted polarized polycarbonate eyewear lens product by obtaining a multilayer wafer having an outer layer, an inner polycarbonate layer, and a polarized layer between the inner and outer layers, applying a gradient tint to the wafer's inner layer, placing the gradient tinted wafer within an injection-molding cavity, and injecting molten polycarbonate directly against the wafer's gradient-tinted layer to form the inner portion of the lens product and to fuse it to the wafer.

Abstract: A filter or lens for common optical apparatus includes a clear center portion and an attenuating peripheral portion where the peripheral portion attenuates off-axis images and passes on-axis images with high signal to noise ratios yet not completely blocking the off-axis images, which lens is well suited for reducing off-axis glare in the optical apparatus that may be handheld optical apparatus such as binoculars, telescopes, cameras, and eyeglasses.

Abstract: Optical thin-films are disclosed that are formed from optical thin films formed on a base plate arranged in a vacuum chamber. The base plates are held on a plurality of retaining frames of a base-plate retainer. The thin films are formed by heating the base plate and emitting a deposition material from a deposition source. The retaining frames are configured to make the entire base plate uniformly heated.

Abstract: A gradient tinted shield may include one or more areas of gradient opacity, varying vertically from a user's eyeline. In one implementation, two areas of gradient opacity are located on the gradient tinted shield, one above the user's eyeline and one below the user's eyeline. Further, an area of constant opacity may be located at the user's eyeline.
