1. A head mounted display device, comprising:
a housing configured to be positioned relative to a head and eye of a user; and,
a visual assembly positioned by the housing in front of the user's eye, the visual assembly comprising:
an electrical layer positioned in front of the user's eye by the housing and comprising side-by-side electronic components, a first subset of the electronic components configured to emit visible light, a second subset of the electronic components configured to emit non-visible light, and a third subset of the electronic components configured to detect the non-visible light; and,
an optical layer positioned on an opposite side of the electrical layer from the user's eye and comprising side-by-side optical components positioned in front of the user's eye by the housing and that allow ambient light to pass therethrough, individual optical components configured to reflect the emitted visible light back through the electrical layer to collectively form an image with the ambient light for the user's eye and to reflect the emitted non-visible light back through the electrical layer toward the user's eye and to refract non-visible light returning from the user's eye through the electrical layer back toward the third subset of electronic components.
