Abstract
A vision testing device includes a hood having an interior space defining a first side and a second side. A first electronic device is operable to project a first image to the first side and a second electronic device is operable to project a second image to the second side. The first image and the second image comprise computer-generated images. A mirror extends from the first side to the second side and is positioned to reflect the first image and the second image. A first viewing lens is in optical communication with the first side and is configured to receive the first image reflected from the mirror. A second viewing lens is in optical communication with the second side and is configured to receive the second image reflected from the mirror.
