Abstract
A vision testing device includes a partition defining a first side and a second side and an electronic device operable to project a first image to the first side and a second image to the second side. The first image and the second image comprise computer-generated images, and the first image is identical to but offset from the second image. 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 configured to receive the first image reflected from the mirror. A second viewing lens is in optical communication with the second side and configured to receive the second image reflected from the mirror.
