Ocular dominance refers to the tendency of one eye to be more effective or preferred for visual tasks than the other. This phenomenon is often observed in individuals, where one eye may provide clearer or more dominant visual input, influencing how they perceive depth and distance. This preference can be influenced by various factors, including genetics, visual experience, and neural processing. In some cases, ocular dominance can be assessed through tests that measure how each eye contributes to visual perception, helping to understand conditions like amblyopia or strabismus.
