How diagnosis, medication, and good intentions may be protecting a world that’s making regulation impossible.

A child can’t see the board.

They squint,

lean forward,

narrow their eyes

until their whole face becomes a question.

Eventually, someone notices

a teacher, a parent, or the child themselves,

rubbing their forehead like it’s been quietly overworked.

Then comes the ritual:

the optometrist,

the chair that tilts back,

the little house in the distance,

Leaves become leaves, not green smudges.

Street signs stop being guesses.

Even their own face in the mirror looks newly real.

We hand them glasses

and call it help, and it is.

But we don’t stop there.

Almost immediately, we begin telling a story.

It runs in the family.

His dad had glasses at eight.

Everyone on my side has bad eyesight.

All of this is true.

Myopia is highly heritable.

And yet here is the detail

that should haunt every argument

we have about ADHD:

heritability never ended inquiry.

We did not treat genes as a stop sign.

We did not confuse correction with explanation.

We did not decide that

because eyesight was heritable,

nothing else mattered.

Because something had changed,

and it had changed fast enough

to notice in a single generation.

So we asked what changed.

We looked at near work,

indoor childhood,

schooling intensity,

screens,

artificial light,

and daylight exposure.

We argued about mechanisms

and tested prevention strategies.

We kept prescribing glasses

without pretending the glasses explained the epidemic.

We held two ideas simultaneously:

people vary in nature,

and the environment can…
