Just found this tonight:
Deluxe Prism Glasses
The Prism Glasses turn your view to a downward 90 degree angle, eliminating the need for head movement. Lie on your back with your head on a pillow, and you'll be able to read a book resting on your chest. These lightweight Prism Glasses feature brilliant optical quality and are the same glasses that enabled Jack Nicholson to view the TV while lying on his back in the movie "The Bucket List".
Now we can all watch TV while lying flat in bed like the cool kids*, no mirrors or flat-screen TVs on the ceiling required.
*Like cyborg-faced comatards
