The person has this very wrong.
Not "very" wrong. Just a little bit wrong.
Eye formation begins during the end of the third week of development when outgrowths of brain neural tissue, called the optic vesicles, form at the sides of the forebrain region. The major structures of the eye- the retina, lens, and eyeball coats- are initially formed by the fifth month of fetal development. During the remainder of the prenatal period, eye structures continue to enlarge, mature and form increasingly complex neural networks with the visual processing regions of the brain.
At birth, an infants eyes are about two-thirds the size of adult eyes. Until after their first month of life, most newborns lack complete retinal development, especially in the area responsible for visual acuity. From the second year of life until puberty, eye growth progressively slows. After puberty, eye growth is negligible.
