3D Movies Fall Flat for People Who Can Not See with Both Eyes at the Same Time (Stereovision)

How to See 3-D -- It Takes Two Eyes to Tango!

Are you or your kid wondering what everyone is oohing and aahing about when watching the many popular 3D movies or 3-D films? Or does 3D viewing cause you or someone you know to experience headaches, stomachaches, nausea, dizziness, motion sickness, confusion, or boredom...?

In order to view 3D stereo images (in 3-D movies, 3-D posters, pictures, books, etc.) you must have two eyes that work together simultaneously as a coordinated team. Two working eyes are definitely required! Check your equipment before continuing.

Looking in the mirror to make sure you have two eyes and that they are both open at the same time is NOT an adequate inspection of your 3D viewing equipment. If you are having trouble seeing 3D, this might mean that you have problems with your binocular (two-eyed) vision or stereo vision (3D vision).

Consider testing your own binocular vision with The Framing Game and The Eye Hop Game for starters.

If you are having a hard time seeing 3D movies, 3-D TV or pictures, etc., have your vision checked by an optometrist who tests AND TREATS stereo vision (i.e. binocular or two-eyed vision). They are called developmental optometrists or behavioral optometrists. You can locate such an eye specialist through this FIND AN EYE DOCTOR Directory.

Even if it turns out that you do have a problem with your two-eyed vision, don't worry! Less than five percent of the population have severe visual disabilities which make seeing in 3D difficult or impossible. This group includes those who have lost an eye or very few of those with medical diagnoses of amblyopia (lazy eye) or strabismus (eye turns -- "crossed eyes" or "wandering eyes"). In MOST cases, two-eyed vision (binocular vision) can be improved with supervised vision therapy.

According to expert eye doctor, Dr. Leonard Press, FCOVD, FAAO, people often ask him, "Is it too late for me? Am I too old for successful treatment of my ...lazy eye, double vision, eye that turns in or out (strabismus), or...? The answer is, age should not be a deterrent or factor. Thanks to the brain's amazing ability to change at any age (see "neuroplasticity"), your vision can also be changed at any age."

Did you know that your eyes are part of your brain? Yep, eyes are made of neural tissue and grow right out of your brain. We see with our brains, not just our eyes!

If you're having problems seeing 3D, take the time to find out if a vision problem may be the cause. Stereovision and binocular vision problems are more common than you might think. At least 12% of people have some type of problem with their binocular vision.

Why Stereo Vision?
Stereo vision is a normal part of human vision and you've got to have it in order to see 3D illusions and have normal depth perception. To learn more abut stereo vision, read Dr. Jeff Cooper's explanation of the Evolution of Two Eyed Vision at All About Strabismus.
