Are mirrors primarily indicated for patients with nasal or temporal visual field loss?

• A. Nasal
• B. Temporal
• C. Superior
• D. Inferior

Answer: (B)

Mirrors expand what the eye can see by redirecting part of the scene into the area the eye can use. When the temporal visual field is lost, objects at the outer edge would normally be missed. A mirror placed on the temporal side can reflect those outer-scene details into the viewer’s usable central/nasal field, effectively widening the horizontal field and aiding mobility and awareness. That direct improvement for the outer (temporal) portion of the field makes mirrors particularly useful for temporal field loss. For nasal, superior, or inferior losses, this reflection approach doesn’t provide the same practical enhancement, so mirrors aren’t as advantageous in those directions.
