About 70% of men have an eye dominance that matches their handedness. BUT, 30% do not. Most right handers have a dominant right eye and the bulk of southpaws a dominant left. These are the people who are well advised to shoot both eyes open (assuming that they are shooting from their strong shoulder).
Best Answer: We all have one dominant eye that focuses a little better on things. You could have one eye that is a little weaker than the other, which - if you need glasses, will be a different prescription than your other eye. Source(s): de.
