Visual space refers to the physical space that surrounds us and we perceive through our sense of sight. It is a crucial aspect of our daily lives, helping us navigate our environments, interact with objects and other people. When referring to visual space, there are several alternative terms that can be used. These include "visual field", "optical space", "perceptual space", "ocular space" and "spatial vision". Each of these terms highlights a slightly different aspect of the visual experience, and can be useful in different contexts such as art, design, or medicine. Nonetheless, they all share the idea that visual space is a fundamental element of human perception.
