Among the most important functions that normally rely on visual capacity are orientation in space as well as the recognition and coordination of behavioral options to be executed in the environment. In humans, cultural techniques such as reading also depend heavily on visual capacity. Vision can also be regarded as a typical environment-related capability; that is, vision is essential for the transaction between the person and his or her environment, especially the physical environment. In contrast, hearing is more concerned with communication (i.e., the social environment).
