The definition of accommodation is
  1. The time it takes to get used to a new prescription
  2. The ability to see in the dark
  3. The muscles in the eye allow the eye to focus at different distances
Explanation
Answer: C - Accommodation is when the muscles in the eye allow the eye to focus at different distances.

The ciliary muscles contract and expand to allow the eye to focus at different distances, making the change from near to far seamless. This reflex action happens automatically to adjust the pressure on the eye for best vision on any object at any distance.
