Abstract

Aspects of the present disclosure relate to head worn computing lighting systems and stray light control.

Claims (11)

1. 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 the perimeter of the head-worn computer to suppress light emitted from a computer display in the head-worn computer, wherein the attachment system is a magnetic attachment system,

wherein the magnetic attachment system includes a magnet of a first polarization attached to the eye cover and a magnet of a second polarization attached to the head-worn computer.

2. 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 the perimeter of the head-worn computer to suppress light emitted from a computer display in the head-worn computer, wherein the attachment system is a magnetic attachment system, wherein the magnetic attachment system includes a magnet attached to the head-worn computer.

3. 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 the perimeter of the head-worn computer to suppress light emitted from a computer display in the head-worn computer, further comprising a front cover adapted to cover a front lens of the head-worn computer to suppress stray light from escaping the front lens.

4. The computer display stray-light suppression system for a head-worn computer of claim 3 , wherein the front cover substantially covers the front lens of the head-worn computer.
