Study: 3D viewing can be fatiguing, cause eye strain

A new study says watching 3D television causes more eyestrain than watching traditional TV. The study, funded by Korean CE manufacturer Samsung, said test subjects also reported more fatigue and a lack of clarity in their vision after watching 3D sets.

The researchers varied the focal point and vergence distance--where on the image the eye is trying to focus--for 24 test subjects, and asked them to watch video and rate their eye fatigue, neck and back pain and vision clarity.

Subjects reported the most discomfort with 3D that varied focal point and vergence distance, especially on more distant screens with images appearing deeper in the screen and with displays that were a short distance away, with images popping off the screen.

The study may provide one more blow to CE manufacturers as they try to popularize 3D television.
