One's dominant eye is the eye that is used while doing monocular task or jobs. The term ocular dominance or eyedness may also be used. Some examples of monocular uses could be; looking through the eyepiece of a camera, using a microscope, and/or shooting a target at an archery range. By using our dominant eye for the proper task we can perform significantly better. If you want to pass in science lab be sure to use your dominant eye when using a microscope.
One study that I found also linked our hand writing and trowing hand to our dominant eye. For those of us that can wink, (Yes, some people cannot wink, just like some of us are unable to whistle), it is a myth that everyone winks with their dominant eye. For most of us, winking is not done by our dominant eye as one might tend to believe. Most of us will tend to wink with our non-dominant eye.
