Not exactly the same concept, but: https://eyewiki.org/AR_Computers_To_Terminate_Eyestrain_And_...

Using AR glasses instead of computer monitors can prevent nearsightedness (myopia) because the virtual image is several meters away.

They're pretty good. It's just that they get uncomfortable to use for long periods of time.

Blame the title character limit.

This isn't true. You can try using adaptive cruise control with lane-keeping on a radar-equipped car on an undivided highway. Radar is good at detecting distance and velocity, but can't see lane lines. In order to prevent collisions, you would need to know precisely the road geometry and lane positions, which may come from camera data, and combine that information with the vehicle information.

Tesla's camera-based self-driving system is still likely at least five years away from being ready, Hall said. Still, he said, "Elon Musk is right about not needing lidar."

What's wrong with him talking about things at Neuralink?

Focus distance for VR headset images is 1.3-2 meters: https://x.com/ID_AA_Carmack/status/1371485209603022853

It doesn't make your eyes completely relaxed, but it's farther than computer monitors and phones/books.

There could be multiple causes.

Why? The Lenovo Legion Glasses 2 documentation mentions the virtual image appears at a size of 126" at a distance of 4 meters away: https://support.lenovo.com/us/en/accessories/acc500372-legio...

Yeah, it’s not a large workspace by any means. But it is still usable. And, it’s larger than what we had with monitors in the 90s and early 2000s.

We're not there yet, but the latest AR glasses like the XREAL One and Lenovo Legion Glasses offer 1080p resolution. It's not retina-quality text, but it's like the workspace of a standard computer monitor, at a large size and at a considerable distance away.

Perhaps. Consider that billions of people around the world have myopia. We need more solutions.

I get no eyestrain, personally, when using my Quest 3. The focus distance of the virtual image is between 1-2 meters, which is pretty good. However, the device gets uncomfortable to use over long periods of time in other areas like the forehead, etc.

Solutions like this can prevent further progression of myopia.

I have Lenovo Legion Glasses 2 (https://www.lenovo.com/us/en/p/accessories-and-software/vr-h...). They look like regular aviator sunglasses.

Oh, okay. But you can still use AR glasses/VR headsets/projectors, with distant (1-3 m) images to prevent myopia induced by extended periods of focusing on close objects when used in place of computer monitors or physical books, magazines, etc.

It’s all downhill from here.

I use a projector and TV side-by-side as monitors. The TV provides better contrast during the day. Unfortunately, the projector model I use—Dell S718QL—has been discontinued. You can look at reviews of recent ultra short-throw (UST) models such as ones from Epson, Hisense, LG, or Samsung. For best results, pair a UST projector with an ambient light rejecting (ALR) screen.

Does Betteridge’s law of headlines apply here?

It seems if you turn the dial all the way to the left on the Toyota Camry (and maybe other Toyotas and Lexuses), everything will disappear except for the gear position.

You could potentially save on glasses and LASIK. You could also potentially use the same projector to watch TV and videos.

I think the arrangement from https://news.ycombinator.com/item?id=42232741 should become more popular. Focus distance is absolutely an issue, and you can probably convince yourself of that by just staring out a window or across the room for a while and comparing the eyestrain you get from that versus reading a book for an extended period of time.

Why?

Using a projector and/or TV as a monitor, at a distance, may help. I've been doing this for a while now, and it works for me.

What?

How do people see at night while driving?

In-browser games like City Sling VR/Mini Golf, YouTube VR, Remote Desktop, or using it as an alternative to notebook computer

That works too. It depends on what you value. If you want more screen real estate while keeping a long distance between your eyes and the screen, then go for the projector.
