“Acuity” (uh-KYOO-uh-tee) – from the Latin for “to sharpen” – is sharpness of perception or vision.
Example (as used by Stephen Budiansky in If a Lion Could Talk): “Horses tend to shy a lot because the construction of their eyes is optimized for a near 360-degree field of view, useful for spotting danger, but the price the horse pays for that is relatively poor acuity and some out-of-focus spots that can cause objects within the field of view to suddenly sail into sharp focus.”
