ABSTRACT:
The optical viewing device for enhanced depth perception of images on a television screen comprises a hollow body of generally rectangular shape having a rectangular opening at the front, opaque sidewalls extending to the back of the device, and an open back. The sidewalls at the back opening are generally formed to provide a substantially light tight engagement with the face of a user. The front opening of the device is covered with one or two layers of mesh screen having the warp and weft diagonal to the rectangular opening at the front of the device. The optical viewing device is sized to locate the mesh screen three and one-half to four and one-half inches from the user's eyes for viewing a television screen at least eight feet from the user.
