3D Vision in the Classroom

3D Vision in the Classroom


3D is an exciting technology that can enhance the viewing experience of movies, television and gaming.  It is not only entertaining, but may also provide opportunities for increased 3D interactive learning opportunities in the classroom and workplace.  Think about the possibilities…….geometry, architecture, anatomy, engineering, sculpture, biology.  Pick one of these subjects and imagine what you might do if you could use 3D images in your lesson plan.  In fact, the trends toward new 3D technology are hard to miss—unless you are one of the millions of Americans who are unable to see it.

 Unfortunately, some people who have even a small eye misalignment, unstable focusing ability, difficulty coordinating vision with other senses or those who lack equal vision in both eyes may not be able to see 3D images properly. Studies indicate that anywhere from three to nine million people have problems with binocular vision, making it difficult to see or enjoy 3D effects. Discomfort, dizziness, or loss of depth perception comes from fatigue due to 3D technology forcing the eyes and brain to make continuous adjustments on images that are near and far away.

 The American Optometric Association recommends seeing a doctor of optometry if you experience any of the following:

  •  Do you experience eyestrain, headaches, or other discomfort during or after viewing?
  • Do you feel nauseous or dizzy during or after viewing?
  • Are you more comfortable viewing 2D TV/movies/games instead of 3D versions?
  • Is it difficult for your eyes to re-adjust after viewing 3D TV/movies/games?
  • Is the 3D viewing experience not as vivid for you as it is for others watching the same picture?

 Watching 3D media can unmask issues such as lazy eye, inadequate eye teaming, poor focusing skill and other visual problems. The good news is that help is available. The president of the American Optometric Association points out that “for the estimated 1 in 4 children that have underlying issues with overall vision, 3-D viewing can unmask previously undiagnosed deficiencies and help identify and even treat these problems….If deficiencies are identified the student can be directed to care consisting of a comprehensive eye exam and treatment with glasses and/or individualized rehabilitative vision therapy.  As an added benefit, this course of action may also assist the child in most all reading and learning tasks.  Overall these 3-D viewing potentials, tied to enhanced and protected vision, provide increased assurance that no child will be denied lifetime opportunities and an equal chance to succeed in school and later in life.”

 Although it is safe and does not cause damage to the eyes, good vision care can insure the 3D experience is comfortable and effective.  For more information on 3D vision, visit www.3deyehealth.org.
