The privacy impact of this is immense, as if you can imagine doing ML training on millions of mugshots to create a model for scanning people's eyes, we've now got super-fancy phrenology. Who needs morality when you have biostatistical markers.

It's conceivable we could probably do the same with gait and voice analysis for other issues as well.

When I saw the title I thought of people I know who have “crazy eyes” (as I’ve heard it called). I can’t even define what it is, but know it when I see it, and often that person seems off somehow. I’ve been trying to decide for a while if it’s real or some sort of confirmation bias after I know them better.

I had the exact same thought. I think these "crazy eyes" come from a predisposition to view other people (e.g. other skin colors, genders, or just other humans) as a threat. It's always that fixed stare, unblinking face, and enlarged pupils. It almost is like right before one's cat decides to launch a sneak attack on your leg as your round the corner, but usually more dangerous (either physically or emotionally).

This is going on in Petaluma, CA right now. A mom claimed people of color attempted to kidnap her children. She describes the eyes of the "perpetrators" below. Fortunately, according to the police investigation, her children were not in danger, from the people who were reported to the police.

There is a lot of speculation about transpired given conflicting video, police statements and eyewitness accounts. Mrs. Sorensen has since deleted her social media accounts and stopped giving interviews. I saw her appeal to mother's to be more guarded with their children:

“There is no other explanation as to why they were doing that besides they were just building the courage,” Sorensen said. “The gentleman looked at me, and his eyes were huge. He saw what was going on, and I just yelled for help.”

This is just personal, but once I had to help my aunt during an extreme bipolar episode. She was violent, paranoid, and hallucinating. One of the most haunting things from that time was her eyes. They seemed hard and staring. When she looked at you, it didn’t feel like it was her in there. Her eyes weren’t shiny and expressive like normal. There was just something frantic and non human in them. Maybe it was just the…

There is a deep part of our brain that controls eye contact. Babies know to stare at faces, even when they cannot recognize one from another. It is a common evolved trait. Dogs, lions, deer, seals, chipmunks, crows, some would say even sharks ... all sorts of animals will "look us in the eye". We expect to see a certain code of behaviour re eye contact. When a person or animal is subject to something that alters that covention we interpret that as "crazy eyes". A dog in pain will look a human in the eye. A dog on hallucinationogenic drugs will not. We must be careful whenever we are interpreting such things as our interpretation can be based more on expectations than reality. The shark is probably not meeting our gaze. Rather, we see an eyeball and expect that it is acting a certain way.

Spend time talking to someone with a false eye. You might not understand why their face seems a little odd. You probably cannot tell which eye is fake (false eyes are far more common than people realize) but you know something is not right.

I always assumed the all kids having glasses anymore thing was just because they spend way too much time on phones and tablets watching tv. It used to be common knowledge that sitting too close to a screen messed up your vision, and somehow we threw that advice out the window.

What if it wasn’t? There were few anecdotal miracle stories that excessive VR usage fixed cross eyes and shortsightedness for some people. Don’t make sense, unless mental well-being had been one part of the cause all along. Not to say everyone with vision problems should jump into dubious “practices” like playing VR games all day long or start taking some drugs, no, but I think a link between vision and mind is an in…

All VR has a sweet spot with a distortion profile that slightly shifts as your eye looks around, which moves your pupil a bit in space, so it is a bit different than normal vision, unless using eye tracking to correct the shift in distortion. Something like that could have had an effect, rather than mental well-being.

Last I heard the major contributor to childhood myopia was a lack of outdoor light exposure. Screen time is a red herring compared to spending daylight hours outside. https://www.businessinsider.com/kids-that-play-outside-need-...

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.

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

Been quite a few of these. At least one turned deadly.

I suspect some of the paranoia is related to the QAnon nonsense.

Eyes are brain

It's a bit of an oversimplification, but it's not too far off the mark. Human vision is pretty poor in terms of resolution and distance. But if you stop and think about it, it's incredible that we see as well as we do, or even at all! Proper vision requires a huge amount of brain real estate. The coordination of muscles involved in movements is incredibly complex. The eyeball is so special that it's got immune privil…

Yes, and... "However, the neural circuitry in your eye only passes a signal along to the brain if several photons are detected at about the same time in neighboring rod cells. Therefore, even though your eye is capable of detecting a single, isolated photon, your brain is not capable of perceiving it. "

Also, evolutionarily, it appears as if eyes were evolved 3 separate times. And: "Eyes and other sensory organs probably evolved before the brain" https://en.wikipedia.org/wiki/Evolution_of_the_eye (which is outstanding on this topic)
