Earlier quoted context omitted.

Outdoor activity is being outcompeted by screens so it seems very relevant to me.

If that study is to be believed, a child catching pokemon on their phone in the park is likely to develop better eye sight than a child reading a book at home. So I think the difference is pretty relevant, and the fact that outdoor activity is out-competed by screens would just be a confounding factor.

Of course, books are a thing, but we all know that without access to screens kids would get bored out of their minds staying indoors. Indeed, that is the premise of the grounding punishment.

So a hypothetical of a boy reading books until Pokemon Go made him spend every second outside just seem like arguing for the sake of arguing.

That was not my hypothetical.

My point is that the recommendation to parents should be to get their kids outside, not to get their kids away from screens (IF that study is to be believed!).

If parents are keeping their kids away from screens but still inside, there may be no real benefits. And there are plenty of ways for kids to entertain themselves inside even without a screen, especially for younger kids.

Not to take away from some of these comments, but the article does not mention anything about casual observation of the eyes signalling mental health issues. The article is highlighting research on diagnosing disorders of the brain using ophthalmological methods (e.g. optical coherence tomography to measure retinal thickness, electroretinography to measure electrical signaling in rods and cones, and angiography to as…

>and may even be early indicators of brain disorders that have not yet manifested themselves in psychological disturbances

It's only a matter of time before someone as unscrupulous as ClearviewAI develops a phrenology tool for identifying psychological disturbances based on "crazy eyes", which will be used extensively by state security services to manufacture suspicion where none is warranted. False positives are a feature not a bug. See, e.g. drug sniffing dogs and [1].

This article will be cited in the marketing material. It will not matter one iota that the research does not actually support that kind of application.

I'm not implying by any means that gender or sexual expression is a mental-health condition - but i've always thought my 'gaydar' pings with certain eyes, specifically male eyes with longer more 'feminine' lashes. probably confirmation bias but I've wondered if others have noticed this

Some women once told me they think eyes with more pronounced lashes make men crazy attractive. So I suppose there's nothing really "gay" about it. Some male actors wear mascara (e.g. Johnny Depp in Pirates of the Caribbean), making them more attractive to women, I suppose. I'd love to see some science behind this though.

oh totally and I agree that the long lashes are cute! I'm like 99% sure I have built up this correlation/intuition theory in my mind because I tend to only look closely at guy's eyes when I'm flirting/dating with them lol.

Though there was an ML study a while ago about 'gaydar' face recognition - I remember it was ripped apart on HN. From my limited knowledge I don't think there are one or even a few significant gene expressions for homosexuality that we know of so seems probably not true.
