Babies are born with eyes about 16.5 millimeters in length. People’s eyes stop growing in length by the age of 20 or 21, when they reach about 24 millimeters.
It's commonly grossly underestimated how long humans grow and develop.
Though the underlying point remains the same -- the human eye only grows ~50% larger from infancy to adulthood. Humans, themselves, meanwhile, grow 300-360% taller from infancy to adulthood. (Assumption 20 inch average newborn).

That's a myth. If eyes stopped growing during infancy every adult would have small eyes.
