Moviegoers aren't the only ones wearing 3D glasses nowadays — doctors could benefit from them, too, a new study suggests.
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 systems. Funded by industry sponsors, the study of 50 surgeons using the new technology showed improvements in surgical precision and speed.

"While the technology still requires some fine-tuning, technology without the need to wear special glasses will increase the popularity of 3D systems in operating rooms," study leader Ulrich Leiner of the Fraunhofer Heinrich Hertz Institute (HHI) in Berlin said in a statement.
Improvements to screens are driving developments in 3D technology. High-definition screens are already available. The next step is ultra-high definition, with a sixteenfold improvement in resolution, according to study co-author Michael Witte of HHI.
To evaluate whether new 3D technology was ready for hospital applications, researchers invited surgeons from the Klinikum rechts der Isar's surgical hospital to test it out. A leading endoscope manufacturer and an international display company funded the study.
The surgeons tested four different systems: 2D, 3D with glasses, 3D without glasses and a mirror-based 3D system. The glasses-free model relied on an eye-tracking camera system that delivered separate images to each eye, creating a 3D effect in the brain.
