3D Vision Syndrome
What constitutes a syndrome?
A group of symptoms that A group of symptoms that collectively indicate or characterize a disease, psychological disorder, or other abnormal condition
So is the 3D Vision Syndrome Really a Syndrome?
Yes.
The symptoms and signs consistently The symptoms and signs consistently include: headaches, nausea, dizziness, a vision induced sense of motion, diplopia, blurred vision and eyestrain; as well as a disconnect between accommodation and vergence.
The 3D’s of 3D Viewing: Discomfort, Dizziness and Lack of Depth
Discomfort:
Since 3D viewing is based Since 3D viewing is based on the eyes converging in front of or beyond the screen, viewing 3D images can potentially create eyestrain and headaches
The 3D’s of 3D Viewing: Discomfort, Dizziness and Lack of Depth
Dizziness:
3D technology can exaggerate visually induced motion sickness …causing consumers to feel dizzy or nauseous during or after viewing 3D content.

The 3D’s of 3D Viewing: Discomfort, Dizziness and Lack of Depth
Lack of Depth:
A viewer lacking binocular i i i l ’t 3D vision, simply won’t see 3D.
While this doesn’t pose any problem viewing the screen, it serves as a “vision screening” that something is abnormal with the viewer’s binocular vision. Photo credit: Photobucket
