What is the dominant eye?

The concept of the dominant eye refers to the eye that plays a primary role in visual processing and coordination during tasks that require depth perception and fine visual detail. The dominant eye is often the one that leads in eye movements, such as during tracking or binocular coordination. When both eyes are available, the dominant eye tends to direct the visual information that is processed more prominently by the brain, making it crucial in activities like aiming, shooting, or even just perceiving spatial relationships.

It is essential to understand that dominance does not necessarily correlate with visual acuity, hence the reason choices related specifically to better vision or quicker focus adjustments are not applicable. Dominance is mostly about the functional role in visual integration and coordination rather than just the quality of sight or how fast one can focus.
