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.

    • 3D Glasses
      Techniques to Achieve 3D
    • 3D in the Classroom: See Well, Learn Well
    • Passive
      3D glasses technology
      Linearly polarized glasses
      Two images are projected superimposed onto the same
      Use a silver screen so that polarization is preserved.
      Can’t tilt head
    • Passive
      3D glasses technology
      Circularly polarized glasses
      Light that is left-circularly polarized is extinguished by the right-handed analyzer, while right-circularly polarized light is extinguished by the left-handed analyzer.
      The viewer can tilt their head and still maintain left/right separation.
    • Circularly polarized glasses
    • RealD Cinema system uses an electronically driven circular polarizer
      Infitec glasses
      Infitec (interference filter technology.)
      Filters divide the visible color spectrum into six narrow bands "super-anaglyph”
      Dolby uses a form of this technology in its
    • Dolby 3D theatres
      Complementary color anaglyphs (use red and cyan)
      Lenticular printing used to produce images with an illusion of depth, or the ability to change or move as the image is viewed from different angles
    • 3D glasses technology
      Active
      Active
      LCD shutter glasses
      A liquid crystal glasses stop or allow light in thru synchronization with the images seen on the screen
      Red eye shutterglasses
      The Red Eye Method reduces the ghosting
    • Active 3D Glasses
      small LCD screens
      when voltage applied lens goes dark
      synced with screen showing 3D content then alternates image viewed
      each eye different angle of view
      creates 3D effect
    • Active 3D Glasses
      this method of 3D cuts refresh rate in half
      Known to cause headaches
      http://www.3d-tvbuyingguide.com/3dtv/3d-glasses.html
    • Active 3D Glasses
      3D Personal Display Spectacles
      two small screens in the glasses
      display separate images to each eye.
      Does not require a television

    • How Does Nintendo 3DS Work?
      two separate outputs at slightly different angles one for your left eye and the other for your right

    • 3D Vision Syndrome
      What constitutes a syndrome?
      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 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 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 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.

    • 3D Vision Syndrome …
      … is comprised of a group of symptoms and physical signs that collectively indicate or characterize a functional vision and/or eye health disorder that manifests when viewing simulated 3D technology. These signs and symptoms include but are not limited to headaches, blurred vision, eyestrain, double vision, dizziness/nausea, decreased depth perception and vision induced motion sickness.
