The Lazyglasses from ThinkGeek are spectacles with two glass prisms that bend your vision 90 degrees. This allows you to read a book or watch television while lying down flat on your back. They are available to purchase online.
Finally, the dream of lying flat on your back, watching TV at your feet, can be realized! Your keyboard and mouse can be upright, while you are prone! Raid the Throne of Thunder from the flat of your back! And who has the energy to mainline every episode of Arrested Development without ever getting up? YOU DO, SON!
