Among kids who study hard, seven or eight out of ten wear glasses. The ones who can't sit still and daydream generally have good vision.
Here's the logic: top students are highly focused β staring at the blackboard or books for forty minutes straight. Ciliary muscles are tense the entire time. Nearsightedness is almost inevitable.
"Bad students" glance at the blackboard, look down, turn to watch birds, whisper to their deskmate. Their eyes constantly switch between near and far focus. The ciliary muscles go through a relaxation routine β contracting and releasing. It's actually the most scientific rhythm for eye health.
As parents, what annoys us about our children is often what wasn't allowed in our own childhood. We were scolded for being playful, punished for lying, shamed for showing off. Those "unruly" parts became forbidden zones in our minds.
But a perfect child β only strengths, no weaknesses, always obedient β isn't a child. It's a prop. Children are children. Playful, mischievous, occasionally lying, occasionally vain. Like a rose β if you love it blooming, you accept the thorns.
He doesn't need to prove he's a "good child." Just like you don't need to prove you're a "qualified adult."
