What is the purpose of peripheral vision testing?

The purpose of peripheral vision testing is to assess side vision and detect potential vision issues. This type of testing evaluates how well an individual can see objects to the sides while focusing on a central point. Peripheral vision is crucial for overall visual function, as it helps in detecting motion and objects that are not directly in front of us, which can be particularly important for safety when driving or navigating environments. By identifying any deficiencies in peripheral vision, healthcare professionals can uncover potential underlying conditions, such as glaucoma or retinal disorders, that may affect a person's overall visual health.

While other options address different aspects of vision, they do not pertain specifically to the role of peripheral vision testing. For example, measuring color perception relates to the ability to distinguish colors, evaluating depth perception focuses on judging distance between objects, and determining reading ability assesses literacy rather than visual field awareness. Each serves different purposes but does not encompass the primary intent of peripheral vision testing.
