Have you heard the terms “dominant eye” and “ocular dominance” but aren't sure what they mean or how you perform a dominant eye test? Here are the basics...

Dominant eye: What is it?

Your dominant eye is the eye that provides a slightly greater degree of input to the visual part of your brain. It also more accurately relays information about the location of objects.

Most of the time, the term “dominant eye” is used when describing the normal visual condition in which the two eyes function well as a team. Plus, the two eyes have equal visual acuity. One eye is simply the “leading” or preferred eye.

But sometimes, “dominant eye” is used to describe the normally sighted and functioning eye in dysfunctional cases of amblyopia and strabismus.
