Which option lists the full range of components included in a functional vision assessment?

Functional vision for orientation and mobility looks at how vision supports real-world movement, not just what a chart says. It includes depth perception to judge distances, the size of the visible area or visual field to know what’s around you, and the medical context behind vision loss (diagnosis) that can impact planning and safety. It also covers core visual abilities like acuity for sharpness, contrast sensitivity for detecting differences in light and shade, and colour vision which can aid color-based cues in the environment. Essential mobility skills—scanning the surroundings, tracking moving objects, and tracing a path—reveal how a person gathers information during travel. The use of visual aids and how different lighting conditions affect vision are included because they directly influence what can be seen on the route. Together, these elements form the full range of what a functional vision assessment should capture for O&M planning. The other options fail to include several of these components, making them incomplete.
