Re: How can a simple eye test show eye dominance?

Dear Betty:

Thank you for the question.

One test that has been purported to show "eye dominance" is as follows:

1) With both eyes open, look at an object in the distance.  
2) Raise a finger and line it up so that your finger is overlapping the 
object.
3) Now close one eye.  If it looks like your finger "jumped" (it is no 
longer lined up with the object), then the eye you closed is "dominant."

This test works because your two eyes have a slightly different 
perspective, and the "dominant" eye was used to line up your finger.
