Abstract: A blue-cut wafer can be coupled to a lens, such that the blue-cut wafer can be configured to reduce by absorption at least a portion of light having a first wavelength range from 400 nanometers to 500 nanometers, preferably from 400 nanometers to 460 nanometers. The blue-cut wafer can permit light having a second wavelength range, the second wavelength range being greater than the first wavelength range, and homogenize a color appearance and a blue-cut performance level of the blue-cut wafer based on the blue-cut wafer having a maximum thickness and a minimum thickness within twenty percent of a nominal thickness of the blue-cut wafer.

Abstract: A polyurethane based adhesive containing one polyol compound derived from caprolactone monomer having a number average molecular weight between 200 and 1000 combined with a polyisocyanate compound. The functionality of the polycaprolactone polyol is between 1 and 4. Other aspects include a polarizing layered structure, a polarized lens and a method for manufacturing same all of which include the polyurethane based adhesive. The adhesive avoids delamination and is useful in optical applications where it will be in contact with water, for example during surfacing or edging process.

Abstract: The optical articles disclosed herein render polarized glare in a certain tunable color that is visually more perceptive than a regular tinted lens or a regular polarized lens. Optical articles, including sunglass lenses, that are configured to color plane-polarized light transmitted through the lens will draw the wearer's attention and help identify the contours or dangers on surfaces in the wearer's field of vision.

Abstract: Disclosed are systems and processes for generating a finished or semi-finished lens, such as a spectacle lens, from a lens blank that includes an intermediate functional layer. Some embodiments of the process involve locating the functional layer and positioning the lens blank according to the location of the functional layer. The location of the functional layer can be ascertained by measuring the thickness of one or more layers of the lens blank. The lens blank can be surfaced on one or both sides to form a finished or semi-finished lens. Other embodiments are also described.

Abstract: A transparent optical element with dual light-polarizing effect comprises a first film forming a linear light-polarizer in a first surface portion of the element, and a second film forming a retarder plate within a second surface portion. The second surface portion is contained in the first surface portion. Such element may form an eyeglass adapted for providing stereoscopic vision by light polarization selection in the second surface portion, while providing protection against excessive light intensity in the first surface portion.
Abstract translation: 具有双光偏振效果的透明光学元件包括在元件的第一表面部分中形成线性偏振器的第一膜和在第二表面部分内形成延迟板的第二膜。 第二表面部分包含在第一表面部分中。 这种元件可以形成适于通过第二表面部分中的光偏振选择来提供立体视觉，同时提供防止第一表面部分中的过多光强度的保护。
