> any thoughts on blue light glasses? I tried them. They worked well enough, but I don't like to wear glasses so I stopped. Also I didn't like how they cut all blue light, including the blue from the sunlight. It's important to get blue light during the day to help your body regulate it's sleep hormone production. > or setting your screens to grayscale? That's orthogonal. The white part of the grayscale still has blu…
why attention?
The OS likes to use color to grab your attention. Red notification dots, bright orange tabs (like on HN), etc.
By going grayscale, it limits how much attention the OS (or any other app) can grab your attention with color.
I tried it, it annoyed the heck out of me, so I went back. But it did work -- it made me less interested in using my devices.

Not necessarily. There is a lot of analog in the eyes beyond the nerves, and we don't know all the effects of ambient light on the entire eye structure. Even if the neural impulses end up being similar (and I doubt that) the eye as a whole organ may not respond the same way. Maybe that heat energy triggers something in the cornea? We don't know.
I don't disagree that UV and IR exposure may be important. Variations in UV exposure are thought to account for changing rates of myopia, for example. There may be non-image-forming receptors with different spectral sensitivities for circadian rhythms. However, the structure and function of circuits involved in color representations has been studied to death, and it overwhelmingly points to a tristimulus model where…
(This may come off a bit harsher than I meant. It's just that I'm surprised to hear someone doubt what I thought was a well-established principle with lots of data behind it. If you do have anything suggesting otherwise, I'd legitimately love to read it.
If not, WebVision is an excellent resource with a long chapter about color. https://webvision.med.utah.edu/book/part-vii-color-vision/co...
The Visual Neurosciences is a behemoth too, if you can find a copy; I don't think it's online.

> they feel perfectly fulfilling and real to me That is the whole point of a simulation. Hyper-palatable food, cocaine, porn etc. they also feel good and even hyper-real in our nervous systems in the short term, but that’s not a good way to judge if they pose long term complications. Though, I’m not saying video chat is necessarily a hyperstimulus, we don’t know yet. > claiming that online interactions aren't real an…
If you've been reading Baudrillard, you might like the blog The Last Psychiatrist, which is a less-rigorous, more ironic take on a lot of similar ideas about hyperreality.
I read both! Thanks! It’s a shame The Last Psychiatrist doesn’t update anymore.

#245Can we quantify the "net screen time" once we subtract away from activities that took up time but have since been replaced/optimized by automation?
But leaving that aside, the 34 years figure is understating the true time spent. That figure is referring to 34 years of 24-hour days. If we subtract 8 hours a day for sleep, it is actually 52 years of our waking hours.

I'm going through TNG right now, and the stories still hold up very well. There are a lot more useful lessons in them than I remember when watching as a kid. I really do like the humankind aspirational nature of the show also.
I went through TNG again a while ago and I was struck by how much I'd forgotten, and how I'd kind of lost my way in terms of my beliefs. I grew up wanting to be like Picard, and watching them again reminded me of that.
Yeah. Picard was a great leader. Humble, stern when needed, compassionate, trusting of his subordinates, etc... An amazing character.

#249"If children get outside enough, it doesn't matter how much they study they do. They don't become myopic," said Ian Morgan, researcher at Australian National University.[0] "Researchers say kids and teens need to get sunlight during the critical years of their development while their eyeballs are still growing.

Reminder that being outdoors and sunlight have nothing to do with myopia. It's about how much light is focusing on your fovea and in peripheral vision. Being outside is just one common way that your peripheral vision isn't constantly in focus because there's not a screen filling up most of your periperal vision.
