Which PERRLA component assesses the eye's ability to focus on near objects?

Accommodation is the eye’s ability to focus on near objects by changing the lens’s shape. When you look at something up close, the ciliary muscles let the lens become more curved, increasing its optical power so the image falls on the retina clearly. In a PERRLA assessment, checking accommodation confirms the eyes can adjust focus from distance to near. This is separate from pupil size, which looks at how large or small the pupils are; light reaction, which gauges how pupils constrict or dilate in response to light; and equal roundness, which ensures both pupils are the same size and shape but doesn’t test near focusing.
