Morphology

acuity = acute (transparent) = acute + ity

Standard derivation from the adjective 'acute' using '-ity'; the sense 'visual sharpness' is a direct extension of 'sharp'.

Etymology

The word acuity comes from the old Latin word acer meaning 'sharp', the same root as acute. So visual acuity means 'sharp' sight, the ability to see small, clear details.
