ACVREP Orientation and Mobility Practice Exam 2026 – Comprehensive Test Prep

Navigating with reduced vision relies on accurate depth cues and awareness of surface changes to place each step safely. A common mobility issue is tripping or stumbling on uneven surfaces, curbs or drop-offs, and changes in terrain, especially when there’s traffic to manage. When depth perception is limited and contrast is reduced, judging step height, edge boundaries, or gaps becomes uncertain, so the foot can land in the wrong place or fail to detect a curb. This combination increases the risk of trips and falls and can lead to overconfidence, where someone assumes the path is clear when it isn’t. Dizziness relates more to balance systems, color discrimination to identifying objects by color rather than navigating space, and fine motor coordination to hand tasks rather than safe ambulation, so they’re less central to typical low-vision mobility challenges.
