Abstract

Aspects of the present disclosure relate to a computer display stray-light suppression system for a head-worn computer comprising an eye cover including a flexible material with a perimeter, wherein the perimeter is formed to substantially encapsulate an eye of a person, and the eye cover including an attachment system adapted to removably and replaceably attach to a perimeter of the head-worn computer to suppress light emitted from a computer display in the head-worn computer.

Claims

1. A light suppression system for a wearable head device, the stray light suppression system comprising:

an eye cover comprising a flexible material, the eye cover having a perimeter, wherein;

the perimeter is formed to substantially encapsulate an eye of a user of the wearable head device; and

the eye cover further comprises an attachment system adapted to removably and replaceably attach to a perimeter of the wearable head device, wherein the eye cover is configured to suppress light emitted from a computer display of the wearable head device.

2. The light suppression system of claim 1, wherein the attachment system comprises a magnetic attachment system.

3. The light suppression system of claim 2, wherein the magnetic attachment system comprises a magnet of a first polarization attached to the eye cover and a magnet of a second polarization attached to the wearable head device.

4. The light suppression system of claim 2, wherein the magnetic attachment system comprises a magnet attached to the eye cover.

5. The light suppression system of claim 2, wherein the magnetic attachment system comprises a magnet attached to the wearable head device.

6. The light suppression system of claim 1, wherein the eye cover is adapted to cover one eye of the user.

7. The light suppression system of claim 1, wherein the eye cover is adapted to cover both eyes of the user.

8. The light suppression system of claim 1, further comprising a processor adapted to detect when the eye cover is attached to the wearable head device.

9. The light suppression system of claim 8, wherein the processor is configured to change a lighting condition of the wearable head device when the eye cover is attached to the wearable head device.

10. The light suppression system of claim 1, further comprising a front cover adapted to cover a front lens of the wearable head device and further adapted to suppress stray light from escaping the front lens.

11. The light suppression system of claim 10, wherein the front cover substantially covers one front lens of the wearable head device.
