Dominant Hand, Dominant Eye Connection
In general, eye dominance goes along with handedness.

Is It Possible to Not Have a Dominant Eye?
Most people have a dominant eye, just as most people have a dominant hand.
It is much more common, though, to have a variation in how dominant your dominant eye is.
For example, some people may have one eye that is only slightly more dominant than the other.
Others may have one eye that is much more dominant than the other.
