> While having two myopic parents does mean you’re more likely to be nearsighted, there’s no single myopia gene. That means the causes of myopia are more behavioral than genetic.
This stinks of faulty logic.

Yeah it’s terrible. There is also no single height gene, but one wouldn’t say height is more behavioural than genetic.
I agree, but it’s worth pointing out that height is also quite strongly affected by environment (we’ve seen average height grow a lot due to improving diets since the Great Depression).
Everything is strongly affected by the environment. For example, if I butcher you, your height will go down. Also all of your organs will stop working.
But height is not affected by the environment in any meaningful way in a modern first-world context; everyone's diet is already maxed out.
