Final answer:
Full color vision, distance vision, and the ability to track objects develop as part of normal visual development in humans. Newborns have limited color perception and lack depth perception, but these abilities improve with time. Nearsightedness is more common in school-age children and may progress until about age 20.
Step-by-step explanation:
Full color vision, distance vision, and the ability to track objects develop as a part of normal visual development in humans.
The eye has three types of color-sensitive cones which are responsible for central vision and color perception.
Rods, on the other hand, are responsible for night vision, peripheral vision, and detecting motion changes.
Color perception in newborns is limited in the beginning, but it improves quickly after birth.
Depth perception, the ability to see in three dimensions, starts to develop later in infancy as the infant becomes mobile.
Vision continues to develop throughout early childhood.
Generally, nearsightedness, or myopia, first occurs in school-age children and may progress until about age 20.
Near point, which is the shortest distance at which a sharp focus can be obtained, tends to increase with age.
Spending a lot of time doing close visual work and having a family history of needing glasses may increase the likelihood of developing nearsightedness in individuals.
