Which condition involves misalignment of the eyes that can affect depth perception on the slopes?

• A. Strabismus
• B. Glaucoma
• C. Cataract
• D. Nystagmus

Answer: (A)

Depth perception on the slopes relies on both eyes working together to form a single, accurate image. When the eyes are misaligned, as in strabismus, the brain may not reliably fuse the two eye images. That disruption makes judging distance, speed, and terrain changes much harder, which can directly affect how you judge gaps, turns, and slope features while skiing. The other conditions affect vision in different ways: glaucoma damages the optic nerve and often narrows peripheral vision; cataracts cloud the lens and blur vision; nystagmus involves involuntary eye movements that can destabilize gaze but isn’t defined by persistent eye misalignment. So, the misalignment described by strabismus best explains how depth perception can be impaired on the slopes.
