What is the average visual acuity of a child at 4 months of age?

At 4 months of age, a child's visual acuity is typically around 20/200. At this stage of development, infants have limited visual clarity, and their vision is still maturing. The visual system and the brain are not yet fully developed, which affects how clearly they can see. A visual acuity of 20/200 indicates that what a person with normal vision can see at 200 feet is only visible to the child at 20 feet. This level of acuity reflects the infant's ability to process visual information, which improves significantly over the first year of life as their sensory systems continue to develop.

Other options, such as 20/400, 20/100, and 20/800, do not reflect the typical developmental range for infants at this age. While visual acuity can vary, 20/200 is a commonly referenced benchmark for infants around 4 months, highlighting that they are still in the early stages of vision development.
