Accommodation is the ability of the healthy eye to focus on both near and far objects. The relaxed state of the ciliary muscle is distance vision, and the flexed state is near vision.
Kids start with a lot of power of accommodation (about 25 D). As you age, the lens in your eye becomes less flexible, resulting in less power of accommodation, which is called presbyopia, especially when it is less than 2.5 D (40 cm through distance correction).
