|The Facedown Mirror is a
optical device that's similar to a periscope except it has 2 mirrors mounted on it. The vertical mirror
reflects the image you are looking at, and the horizontal mirror reverses
it back to the correct orientation. When looking down on the
mirror, the image is as if you are looking forward.
This device is primarily used for watching TV or seeing things and people without looking up. Compliance to the facedown position is enhanced with this mirror.
