Do infants have a large or small depth of focus?

Explanation:
Infants have a large depth of focus. Depth of focus is the range of refractive error over which the image on the retina remains acceptably sharp. In babies, accommodation is immature and pupil size is small, which together increases the eye’s depth of field. This means the retina can still receive a reasonably clear image over a wider range of focusing errors, even though their ability to actively fine-tune focus is limited. As children grow, accommodation becomes more reliable and pupils enlarge, which reduces depth of focus.
