3D glasses help doctors perform surgery when their hands are obscured from view. Moviegoers are not the only ones wearing 3D glasses nowadays. A new study suggests that doctors could benefit from them, too. In the past, doctors have been skeptical of using 3D technology in their work, preferring to rely on their own experience. But that may change, thanks to improved 3D glasses and even glasses-free technology. Funded by industry sponsors, the study of 50 surgeons finds that use of the new technology improves surgical precision and speed.
