The invention relates to eyewear and lenses for controlling and/or blocking the absorption of particular bandwidths of light that can impact the physiology of the wearer. The eyewear lens is adapted to selectively permit the relatively greatest percentage of a light within a wavelength range of between about 400 and 490 nanometers. The eyewear lens selectively permits the passage of light of the given wavelength range over one or more subregions of the eyewear lens. The one or more subregions cover in total at most 25-50% of the lens. The peak transmission level within the range between about 400 and 490 nanometers is at least about 70% and the passage of light outside of the range between about 400 and 490 nanometers is less than about 70%.

METHOD FOR MAKING A GRADIENT COLOR POLAR LENS WITH A NON-POLAR NEAR VISION ZONE
20210255487 · 2021-08-19 ·

Disclosed are methods for preparing partially polarized optical articles. A polarizing element is used to cover at least a portion of the front surface of an optical article to form a polarizing zone and a non-polarizing zone on the optical article. The optical article is then tinted to produce a gradual color transition between the polarizing zone and non-polarizing zone of the optical article.

SYSTEMS AND METHODS FOR EXTERNAL LIGHT MANAGEMENT

An augmented reality system includes a light source configured to generate a virtual light beam. The system also includes a light guiding optical element, the light guiding optical element is transparent to a first real-world light beam, wherein the virtual light beam enters the light guiding optical element, propagates through the light guiding optical element by total internal reflection (TIR) and exits the light guiding optical elements. The system also includes a lens disposed adjacent and exterior to the surface of the light guiding optical element. The lens is configured with a gradient tint that transmits less real-world light at a world side top portion of the lens and transmits more real-world light at a world side bottom portion of the lens, wherein rainbow artifacts, generated from inadvertent diffraction of the overhead real-world light by the light guiding optical element, is minimized.

Method of making an optical article with an inkjet printing device

A method of making an optical article having multiple light-influencing zones can include: forming an alignment coating layer having a first alignment region and a second alignment region over at least a portion of an optical element; applying at least one anisotropic material over the first alignment region and the second alignment region by an inkjet printing device; and applying at least one dichroic material and/or at least one photochromic-dichroic material over at least one of the first alignment region and the second alignment region to form a first light-influencing zone over the first alignment region and a second light-influencing zone over the second alignment region.

A visual field observation training lens is disclosed, along with corresponding training eyewear. An associated method for training visual observation toward a designated field of view is provided.

Ophthalmic lens

A thin film coating for an ophthalmic lens is provided, that comprises alternating layers of high and low index materials. The coating attenuates the transmission of light and has a spectral reflectance curve characterized by a reflectance of at least about 90% in a range from 320 nm to 420 nm, by 50% at 440 nm, by 5% or less at 460 nm, and wherein the spectral reflectance curve is monotonically or strictly decreasing between 420 nm to 460 nm.

Method for coloring an optical element in a non-uniform linear pattern

A method for coloring an optical element in a non-uniform linear pattern is provided. The method includes (a) preparing at least one colorant composition containing at least one photochromic material; (b) depositing the colorant composition on at least one surface of the optical element in a controlled, predetermined pattern using an inkjet printing apparatus to provide a linearly gradient color pattern on the optical element when the optical element is exposed to actinic radiation; and (c) drying the colorant composition on the surface of the optical element. An optical element prepared by the method also is provided.
