What is the definition of functional vision?

Functional vision refers to the ability to use vision effectively to perform everyday tasks and activities. This encompasses not only visual acuity—how well one can see—but also peripheral vision as well as the ability to synchronize visual input with physical actions.

When considering the definition of functional vision, it is essential to recognize that it is not limited to seeing colors or being able to see clearly at a distance. Rather, functional vision involves a comprehensive capability that allows individuals to navigate their environment safely and efficiently, engage in tasks such as reading, driving, and recognizing faces, and perform interactions with their surroundings effectively.

The correct definition emphasizes both visual acuity and peripheral vision, as both are critical for comprehensive visual functioning in daily life. This holistic view is fundamental in assessing visual abilities in various contexts, particularly in assessing how vision impacts overall quality of life and daily functioning.
