The ability to use residual vision effectively to complete daily tasks is known as what?

The concept of functional vision refers to an individual's ability to use their residual vision in a practical, everyday context. It encompasses not just the presence of vision but how effectively a person can use that vision to accomplish daily tasks, such as reading, navigating through the environment, and recognizing faces.

Functional vision involves evaluating how visual impairments impact daily experiences and determining strategies to maximize the use of available vision. This could include modifying environments, using assistive devices, and employing specific techniques to enhance vision-related tasks. The focus is on the real-life application of vision abilities in various settings.

While visual efficiency relates to how well a person can utilize their vision under optimal conditions, and residual vision specifically describes the remaining vision after impairment, functional vision captures the holistic use of these visual components in daily life situations. Poor central vision is a limitation of vision capacity but does not address the broader application of what one can accomplish with the vision they have.
