Eye dominance or ocular dominance is the tendency to prefer visual input from one eye, and it was first discussed by Rosenbach in 1903 (Porac and Coren 1976). It refers to the eye used preferentially in different forms of visual alignment such as looking through a telescope and microscope, shooting, and other such monocular activities (Reiss and Reiss 1997). It was believed that when using the dominant eye, images may appear larger (Porac and Coren 1984) and clearer (Porac and Coren 1982) and also that the stabilized retinal images fade slower compared to the nondominant eye. However, the dominant eye is not necessarily the eye with better visual acuity (Kommerell et al. 2003) and some studies show that there was no association between the size of the object and the eye dominance (McManus and Tomlinson 2004).
Regarding the connection between the dominant eye and the dominant hand, there have been conflicting results so far. Some studies done in athletes suggested that the ocular...
