## Abstract

This invention is augmented reality eyewear with a radial, honeycomb, or nested-ring array of selectively-movable reflective elements. These reflective elements can each be moved from a first configuration which is parallel to a line of sight from an eye to a second configuration which is perpendicular to this line of sight. The second configuration reflects light displaying a virtual image to the eye and blocks environmental light in the area of the virtual image. Since light from the environment does not shine through the virtual object, the virtual object appears solid instead of “ghost like.”

## Claims

### Claim 1

Eyewear for displaying augmented reality comprising:
an eyewear frame;
at least one lens held in front of an eye by the eyewear frame;
at least one light emitter on the eyewear frame; and
a radial array of selectively-movable reflective elements which are part of, or attached to, the lens; wherein reflective elements in the radial array can each be selectively moved from a first configuration to a second configuration, and vice versa; wherein a reflective surface of a reflective element in the first configuration is substantially parallel to a line of sight extending out from the eye, thereby allowing a first percentage of light from the environment near the reflective element to pass through the lens toward the person's eye; wherein the reflective surface of the reflective element in the second configuration is substantially perpendicular or at an acute angle relative to a line of sight extending out from the eye, thereby allowing a second percentage of light from the environment near the reflective element to pass through the lens toward the person's eye, wherein the second percentage is less than the first percentage, and wherein the reflective surface of the reflective element in the second configuration reflects light from the at least one light emitter toward the person's eye.

### Claim 2

Eyewear for displaying augmented reality comprising:
an eyewear frame;
at least one lens held in front of an eye by the eyewear frame;
at least one light emitter on the eyewear frame; and
a honeycomb array of selectively-movable reflective elements which are part of, or attached to, the lens; wherein reflective elements in the honeycomb array can each be selectively moved from a first configuration to a second configuration, and vice versa; wherein a reflective surface of a reflective element in the first configuration is substantially parallel to a line of sight extending out from the eye, thereby allowing a first percentage of light from the environment near the reflective element to pass through the lens toward the person's eye; wherein the reflective surface of the reflective element in the second configuration is substantially perpendicular or at an acute angle relative to a line of sight extending out from the eye, thereby allowing a second percentage of light from the environment near the reflective element to pass through the lens toward the person's eye, wherein the second percentage is less than the first percentage, and wherein the reflective surface of the reflective element in the second configuration reflects light from the at least one light emitter toward the person's eye.

### Claim 3

Eyewear for displaying augmented reality comprising:
an eyewear frame;
at least one lens held in front of an eye by the eyewear frame;
at least one light emitter on the eyewear frame; and
a nested-ring array of selectively-movable reflective elements which are part of, or attached to, the lens; wherein reflective elements in the nested-ring array can each be selectively moved from a first configuration to a second configuration, and vice versa; wherein a reflective surface of a reflective element in the first configuration is substantially parallel to a line of sight extending out from the eye, thereby allowing a first percentage of light from the environment near the reflective element to pass through the lens toward the person's eye; wherein the reflective surface of the reflective element in the second configuration is substantially perpendicular or at an acute angle relative to a line of sight extending out from the eye, thereby allowing a second percentage of light from the environment near the reflective element to pass through the lens toward the person's eye, wherein the second percentage is less than the first percentage, and wherein the reflective surface of the reflective element in the second configuration reflects light from the at least one light emitter toward the person's eye.
