What is monocular vision?

Monocular vision refers to vision that is primarily used with one eye only. This type of vision is important in various contexts, such as when one eye is impaired or injured, or when a person is focusing on an object without the need for depth perception, which typically requires both eyes. Monocular vision allows a person to see the world primarily with a single eye, providing a broad view of the environment without the additional depth cues that binocular vision offers.

In the case of options that discuss the requirements for vision, such as needing both eyes, those would not apply as they directly contradict the definition of monocular vision. Additionally, the references to distance vision or vision enhancement through corrective lenses are more about the quality or conditions of vision rather than the fundamental aspect of using one eye versus two. Thus, the identification of monocular vision as useful with one eye is the most accurate aspect of this concept.
