VR headsets have lenses, so (AFAIK) your eyes should focus farther away and create less strain than a small TV. Or a phone.
I can confirm, I’m shortsighted and I have to wear glasses in VR or I can’t see.
Same. It sucks since my eyes keep getting worse so I have to buy new lenses every year.
VR headsets, 3D TVs, and 3D movies all have the same issue as far as strain is concerned.
Our brains expect our eyes to focus on what they’re pointing at. If your eyes are pointing at something nearby, we focus near. If we’re pointing at something far away, we focus far.
All the various 3D solutions have a fixed distance and fake the 3D by having each eye get a slightly different angle on the image. The mismatch between where our eyes are pointing and where they are focused can cause problems.
Until 3D reaches the level of a Star Trek Holodeck, it’s going to cause trouble. Ok for a short time, but you wouldn’t want to spend all day doing it.
(this is all me paraphrasing what my eye doctor wife told me, so don’t expect me to know any more about it)
Yeah but what if it’s possible to neurologically train yourself out of that focusing behaviour?
My guess is that you’d have problems when you tried to see in the real world.
VR headsets exist, this isn’t theoretically. I use mine regularly never had that problem.
What if you learn to turn it on and off?

In fairness, CRTs could emit a lot of UV and some xrays (particularly older models or ones with degraded screens)
/shitty conspiracy theory
…or was the constant exposure from X-rays keeping all of our cancer at bay. And with the removal of that lifesaving treatment, we’re all rapidly being overcome by our uncheck cancer.
Look at the data and see when LCD TVs first entered the American consumer market. With the removal of CRTs, our cancer rates exploded!! Coincidence?! (yes its just a coincidence)
This looks like it’s not adjusted for population size so it’s basically just showing population growth.
Also doesn’t say what kinds of cancer. In those same time periods, lots of chemicals and substances have been introduced while CRT TVs disappeared. We might not have cancer causing rays from our TVs anymore, but we’re eating more cancerous materials, in, on or around our food everywhere … not to mention surrounding ourselves with plastics, chemicals and substances while closing ourselves inside perfectly sealed homes that trap everything inside for us to breathe and ingest.
We’re basically the Romans from a thousand years ago who installed lead in everything everywhere and basically poisoned themselves. We call them stupid for not knowing that … we’re doing the same thing to ourselves now with a thousand other chemicals.
I’d also assume better awareness, and screening procedures, much like audhd spectrum folks.
If we go into detail, VR headsets also use thick lenses and optically the screens are like 2 meters away.
that explains my sterility. i always watched with my balls glued to the screen
I mean is there any other way?
Only if you Australian, mate.
Yeah, even if they didn’t weight too much, you wouldn’t strap a CRT or 2 to your face due to the various emissions.
Let your kids sit as close to the 80" LED as they want, as long as they aren’t blocking your view. ;)
Yeah was gonna say, the don’t sit too close thing was about CRTs, basically every other display technology is not harmful in this way
First time I am mad at a YES, BUT, because it is very far from accurate.
The “dont sit close to the TV,” thing is objectively truth and is even worse today.
I used screens a lot growing up, including a laptop and various portable games like the Gameboy and PSP
This led to my eyes slowly developing the need for prism on my lenses, because they over-correct now focusing on close objects.
Nowadays smart phones are this problem but way worse too, if you sit in the dark holding it way too close, especially with glasses on, you are slowly deteriorating your eye muscles.
Unless you exercise them of course, every 20-30min. But most people dont do that.
I now am having to do constant daily exercises to slowly undo my prism, a year and a half ago I had a prism of 5.0 on each eye, this month I finally got it down to 2.5, which is solid progress!
However VR doesnt have this issue, its a virtual image that appears to be 2 to 10 or more meters away, so your eyes are focusing like looking at something far away.
Used to be as people got older and their lenses lost flexibility they’d develop farsightedness (presbyopia) and need reading glasses, now it’s common to become shortsighted instead, due to screens. VR may help, or at least let you choose your own adventure.
Prism is neither near nor far sighted issues.
Prism is a muscle problem, where the actual muscles of your eyes get weaker because you arent using them as often to focus on objects far away, so they lose flexibility.
Akin to how if you sit in a chair all day and arent actively stretching purposefully, you lose flexibility in the rest of your body too.
As far as I know, focusing on objects has no impact on eye shape changes, its just genetic on which way your eyes start to squish/stretch as you get older. Thats just a byproduct of the fact our face and tissues change as we get older.
