Bed Prism Spectacles

The main idea of these Bed Prism Spectacles is that you can read a book or watch TV while  lying flat on your back and resting your head on the pillow! Using these special prism glasses you won’t have to twist your neck and strain your eyes, because they can turn your point of view to a downward 90 degree angle, thus avoiding a head movement. Also appropriate for people with limited mobility.
