SPATIALLY SELECTIVE TINTING ARCHITECTURE FOR HEAD-WORN DEVICES - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18137393 Titled 'SPATIALLY SELECTIVE TINTING ARCHITECTURE FOR HEAD-WORN DEVICES'

Simplified Explanation

The abstract describes a head-worn device (HWD) that is designed to reduce glints. The HWD includes a frame that is worn by the user and a lens with a tint that blocks some ambient light. The lens also has an aperture. The HWD also includes a waveguide that directs light to the aperture of the lens. The lens and waveguide are aligned in a way that blocks ambient light from reaching the user, while allowing unattenuated light from the waveguide to pass through.


Original Abstract Submitted

To help reduce glints in head-worn device (HWD), a HWD includes a spatially selective tinting architecture. To this end, the HWD includes a frame to be worn by a user. Further, the HWD includes a first lens that has a first portion including a tint configured to block at least a portion of ambient light and a second portion including an aperture. Additionally, the HWD includes a waveguide having an outcoupler configured to provide light to the aperture of the first lens. The first lens and waveguide are aligned such that a portion of ambient light from outside the HWD is blocked before reaching the user while light from the waveguide passes through to the user unattenuated.
