• Right / left dominance is the tendency to favor
  one side of the body over the other. People
  generally have a dominant eye, meaning the brain
  chooses between images perceived by the right eye
  and the left eye. If neither eye is dominant, the
  image jumps from one eye to the other. There is
  no accepted correlation between hand dominance
  and eye dominance.

Procedure Hold an index card with a small hole
in the center at arm's length. Look through the
hole with both eyes at a distant object. Close
one eye, then the other. The eye that keeps the
object centered in the hole is the dominant eye.
