3D Vision Syndrome:A Technologically Induced Visual Impairment

1,458

Published on

3D Vision Syndrome is a public health imperative that if left undiagnosed and untreated will result in millions of individuals world wide who cannot benefit or enjoy 3D content. Individuals experience many symptoms including but not limited to headaches, blurred vision, double vision, asthenopia, eyestrain, and vision induced motion sickness. This disorder can be diagnosed and then treated with glasses, prisms, and optometric vision therapy. Once treated most individuals can then enjoy and benefit from viewing 3D content.

  51. 51. 3D Vision Syndrome<br />What constitutes a syndrome?<br />A group of symptoms that collectively indicate or characterize a disease, psychological disorder, or other abnormal condition<br />
  52. 52. So is the 3D Vision Syndrome <br />Really a Syndrome?<br />Yes.<br />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.<br />
  53. 53. The 3D’s of 3D Viewing: <br />Discomfort, Dizziness and Lack of Depth<br />Discomfort:<br />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<br />
  54. 54. The 3D’s of 3D Viewing: <br />Discomfort, Dizziness and Lack of Depth<br />Dizziness:<br />3D technology can exaggerate visually induced motion sickness …causing consumers to feel dizzy or nauseous during or after viewing 3D content.<br />
  55. 55. The 3D’s of 3D Viewing: <br />Discomfort, Dizziness and Lack of Depth<br />Lack of Depth:<br />A viewer lacking binocular 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.<br />Photo credit: Photobucket<br />
