For 20/20 vision in infants measured by subjective testing, what is the typical age?

Explanation:
Subjective visual acuity testing relies on the child’s ability to recognize and indicate optotypes, which means they must understand the task and communicate what they see. That level of symbol recognition and verbal or pointing response typically develops around age three. Before that, infants and toddlers can’t reliably perform these tasks, so acuity is usually measured with objective or preferential-looking methods. By about three years old, many children can accurately identify symbols on a chart and demonstrate 20/20 acuity when tested subjectively.
