THE FRAMING GAME

In order to see 3D your brain has to use the visual information from both eyes. If the two eye views are too different and cannot be matched up, the brain will be forced to make a choice. It will reject all or part of the information from one eye. The brain can suppress or turn off visual information it cannot use. The Framing Game can tell you whether both your eyes are TURNED ON at the same time. The illustration to the left demonstrates what should happen.

• Center your nose over the brown eye below.
• Focus your eyes on the single brown eye.
• Put your free thumb in front of your nose.
• Continue to focus on the eye. If both eyes are on, you will see two thumbs framing one eye.
• Now, switch your focus to your thumb. You should see two eyes framing one thumb.

SUCCESSFUL?

PROBLEMS?

• Follow the instructions again and pay close attention to where you're focusing your eyes.
• If you wear lenses, try it without them.
• Can't see two thumbs (or two eyes)? Or does one thumb disappear and reappear? Or does one thumb appear faint -- like a ghost image? You may want to consider having a comprehensive eye examination which includes the testing of binocular vision. To locate a vision care professional in your area, consult the Directory of Vision Care Providers
• Don't give up. You don't have to have perfect binocular vision to attempt 3D viewing. Viewing the 3D images at this site can reinforce and strengthen your binocular skills. Learn about how eye doctors use 3D images to improve vision.
