Which environmental change can help reduce vision-related balance risk?

• A. Lighting
• B. Poor sight
• C. Depth perception
• D. Oculomotor nerve damage

Answer: (A)

Improving lighting enhances vision-based balance by providing clearer visual information that guides posture and movement. When lighting is good, visual acuity improves, contrast is clearer, and depth cues are easier to interpret. This helps people detect hazards like steps, edges, and uneven surfaces earlier, allowing the body to adjust stance and foot placement to avoid a stumble or fall. Poor sight describes a condition rather than something you change in the environment. Depth perception is a visual function, not an environmental modification, and oculomotor nerve damage is a neurological impairment affecting eye movement, not an environmental change you can apply to reduce risk.
