Lazy Glasses, also known as 90 degree glasses are optical glasses that allow you to read in bed or watch TV while lying flat on your back. The perfect solution for those with limited mobility, these unique bed prism glasses are great for preventing neck cramps or eye strain. The Lazy 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. People who wear spectacles can wear it only while they are wearing contact lenses.
