A common danger in profession of dentistry is spinal degeneration where the vertebrae in the spine rub against one another, leading to a narrowing of the disc space and end plate sclerosis. With age, this becomes extremely painful and restricts movement.

This is due to the poor posture that the develops from sitting in a bad position for many hours of the day.

Dentists often use a loop as a hands free magnifying glass. Why not incorporate a set of mirrors into this loop, allowing the Dentist to resume a comfortable position?

Dentist already have to adjust to view the hind side of upper teeth and some lower teeth too. Endodontists don't even look at the patient the majority of the time-- they look through a microscope. Surgeons look at a monitor.

It isn't only dentists who have this problem, geeks do too! Why not also make a super uncool set of glasses that allow us to look straight ahead, while still seeing the screen or keyboard, provided that we could get the image the right way? Just a thought- you can see screen on 3/4 and keyboard on the other 1/4 of the mirror.
