Her er en liten test på hvilket øye som dominerer ( i likhet med å være venstrehendt, høyrefotdominert osv..)

Fixate a small distant object with your eyes and point directly at it with your forefinger. Now close one eye. Now change eyes. Which eye was open when the fingertip remained in line with the small object? (When the other eye, the non-dominant one, is open and the dominant eye is closed, the finger will appear to move to one side of the object.)
