What are pinhole eyeglasses?
Pinhole eyeglasses are an interesting invention in the world of optometry. Otherwise called stenopeic glasses (or "little opening" in Greek), each metal or plastic "lens" has a series of tiny perforations, usually no larger than a pin's head. Light enters through each perforation, increasing the depth of field and giving the retina no "blind spots". Only what is directly in front of the retina is taken into vision. The Chinese discovered pinhole technology in the 5th century, and these glasses were used by the public beginning in the middle of the 20th century. A pinhole camera follows the same technology.
