At-home screening test for 3D vision

Are you having trouble seeing 3D? Digital Life on MSNBC Today recently included an article written by Suzanne Kantra on an at-home screening examination for your 3D vision abilities (click here for the link to the article). 

The test requires only a piece of string and perhaps some optional beads. Although crude, the test describes the Brock string, one of the more classic tools used by optometrists in vision therapy for problems with converging or diverging the eyes. Of course, performing the test at home is not a substitution for a comprehensive eye exam by a licensed optometrist, but may be helpful as an initial indicator of your ability to view in 3D.

Regardless, any symptoms of headache, blur, eyestrain, or inability to see 3D entertainment should be addressed by a professional, who may be able to help you to appreciate 3D through either glasses or visual training. The VPI continues to be a leader in research in this particular area, discovering and publishing the best methods of detecting and treating computer and 3D vision disorders.
