Answer 1

When you grow up, your head and eyes shape grow and change too. If it doesn’t grow right, you’ll have problems to see objects from a far distance. When your head stops growing (age 20-25) it plateaus.

At age 40-45 something else happens. The muscles that control your eyes are stiff so they can’t contract enough to put something in a close distance on focus.
