Certain varieties of 3D displays cause further eye fatigue, consistent with a study printed by the Journal of Vision that was funded partially by Samsung's R&D arm.
A group of researchers from the University of Califonia-Berkeley found that when take a look at subjects watched 3D displays, they reported a lot of eye strain and fatigue and fewer vision with changes thorough of the screen and therefore the depth of the 3D image.Researchers conjointly found the link between image depth and nearness of the screen conjointly played a job in eye strain.
Ars Technica: the long run of lighting
Twenty-four participants within the study were shown 3D video at numerous viewing distances, and then tried and true questionnaires on their eye fatigue, neck and back pain, and vision clarity.
In the video clips, the authors were varying the put concentration, that is that the surface of the screen, and therefore the vergence distance, that is where within the image on that the eyes are fixating. For 2nd video, these points are invariably one and therefore the same, however in 3D video the vergence distance varies, and may be either deeper than the surface of the screen or in front of it.
The participants responded that they experienced a lot of eye strain and fatigue from the video with totally different vergence and focal distances, a feature of 3D that has long been presupposed to cause eye strain (particularly when the 2 distances didn't mimic a practical portrayal of 3 dimensions).
