The present invention relates to dichromic mirrored patterns on fashion eyewear that exhibits variable opacity on the exterior of a photochromic lens in response to changing lighting conditions wherein the pattern can go from virtually transparent to opaque. The dichromic mirror pattern(s) can be coated in multi-color pattern sections and can be coated so that some pattern sections have variable opacity and other pattern sections have a fixed high opacity. The effect can also be produced on an optical film to be applied to many optical surfaces.

Methods and apparatuses related to fiducial designs for fiducial markers on glass substrates, or other transparent or translucent substrates, are disclosed. Example fiducial designs can facilitate visual recognition by enhancing edge detection in visual perception. In example fiducial designs, optical features on glass substrates can re-direct light so as to present a bright image region. Such optical features can include surface relief patterns formed in a coating on the surface of glass substrates. An exemplary method for manufacturing the fiducial markers can involve transfers of a fiducial design across a master mold or plate, a submaster mold or plate, and a target glass substrate. A fiducial marker can facilitate the use of the substrate in a variety of applications, including machine vision systems that facilitate automated performance of manufacturing processes on input working material.

A mat has an embedded array of light sensors under a micro-faceted lens array to provide an array of light intensity values for various incident angles of incident real world light. Virtual objects may be projected onto the mat and, using the information from the light sensors, virtually illuminated to match the real-world lighting environment. A touch sensor array may be embedded in the mat to allow users to interact with the virtual objects and provide other input. The surface of the micro-faceted lens array may be coated with a patterned infrared (IR) reflective coating, such that the mat passively reflects a specific band of IR wavelengths in a pattern to act as a fiducial marker.

Disclosed is an optical scope including an objective lens, an eyepiece lens, and a reticle, wherein a field lens having negative power is disposed in at least one of a front and a back of the reticle disposed on an image formation surface of the objective lens to increase eye-relief.

A rifle scope has an eyepiece and a reticle, and wherein the reticle when viewed through the eyepiece displays a horizontal center line that is at the vertical center of the display, and wherein below the horizontal center line there is a set aiming lines, each marked by a first indicium on a first horizontal side of the aiming line, indicating an angle measured in minutes of angle, from the horizontal center line. Finally, a subset of the aiming lines is marked with a second indicium, on a second horizontal side, opposed to the first horizontal side, of the aiming line, and wherein each the second indicium indicates distance in inches from the brisket to the top of the shoulders of a type of deer.
