Electrochromic systems for head-worn computer systems

Abstract

A removable lens for glasses includes an electrochromic layer adapted to transition between at least two states of a transparency level dependent on an electrical condition applied to the electrochromatic layer and an electrical connection element physically adapted to make an electrical connection with the electrochromic layer, wherein the electrical connection element is positioned to align with a variable-power electrode mounted on the glasses such that, when the removable lens is mounted on the glasses, the variable-power electrode and the electrical connection element make the electrical connection between the variable-power electrode and an electrically conductive layer of the electrochromic layer.

Dependencies are inferred from the claim text.
