What Are Our Eyes Doing in Virtual Reality Headsets? An Optometrist Explains

[@zmadcat]

I think the major reason for eye strain in VR is the dissonance from the fixed focal point to the screen in the headset (close to infinite) and the convergence point of both eyes to the objects in 3D, the closer it gets the worse it is because the eye naturally wants to focus to the real distance of the object

[@charlesbevitt6727]

Gabriel Ribas which is why virtual reality is for old folks. I've had cataract replacement lenses in both of my eyes and they don't focus at all and I don't have a problem at all.

The HUD is rendered wrong if your eyes have to converge on it. Real HUDs use collimator lenses that make all of the light rays parallel to ensure that they always appear at infinity.

[@thesral96]

But part of the feature is that you can tell how far something is in VR with just one eye. If you'd use that then the only 3D effect would be with both eyes. It's just realistic that too near objects appear blurry.

[@TheTEDfan]

Most VR headsets have fixed fixed focal length lenses. Fixed focus make your eyes lazy and if exposed for very long times you will start to have difficulty focussing over a wide range. This is just the lens in your eye. In addition the relation between true distance in reality and how much your eye lens has to focus will be broken in VR. This may result in your eyes sometimes taking longer to focus. Like a slow autofocus on an old SLR. That is even when they can. Especially kids should not only look at books or nearby screens but also play outside to get exposure to seeing things over a wide range of distances. It is no coincidence that young book worms often end up with glasses.

[@HeartlessSora1234]

This is great! I've been wondering about these exact questions since I've noticed I get headaches relatively quickly in vr compared to using just a pc screen. Glad there's likely no long term damage happening.

[@VirtualrealitygingerOfficial]

+Hartlezoro Glad I could give you a little peace of mind :) I was really curious myself, and thought there might be others out there that were interested too!

[@KielanGaming]

This is great, I had read some articles that where worded in a way that your eyes are gonna get damaged using VR headsets and about the danger of blue lighting in headsets, of course, it turns out VR is no worse than looking at your cell phone and VR is better because you move your head and eyes more to look around. Really it's funny how they talk about how we don't know the long term effects which is true, but given what we do know, it's highly unlikely this is going to mess up your eyes.

[@robertrowland1061]

1:57 If the Doc is seeing double, my guess is the Interpupillary distance on the CV1 needs to be properly adjusted. I have a DK2 and have never seen double with it.

[@NoMoreBSReviews]

IPD was adjusted to match. He wasn't seeing double for the VAST majority of this video - only when his eyes needed to converge significantly to see the HUD display inside of his helmet.

[@robertrowland1061]

Fair enough.

[@ZmanGamesp]

take your finger and put it a few inches away from your eyes and look at your monitor, you're going to see 2.

[@Dannysgamess]

I just bought my Oculus Rift with touch controllers a few days ago, bearing in mine I have never ever tried VR before buying the headset. When I first starting using it I was blown away by how immersive it was, was not expecting it to be that good really. Shortly after your attention is drawn more towards the graininess and I guess that's what they call the screen door effect? Damn if the lenses actually showed real HD without the grainy texture I'd be in heaven. After wearing the headset for about 1 hour I started to feel my eyes ache, I felt abit dizzy at first which passed off but I suffered with headache soon after. I'm still currently getting the eyestrain, maybe I need my eyes tested but i've tried tweaking the slider for the lenses but still get the eyestrain. I could not play with it on for more than 2 hours at a time, it's just to much for my eyes. Maybe I will get used to it in time but the overall experience is pretty good to be honest.

[@xapu8775]

[@kraftzero2947]

It blows my mind with my vr. First time i wore it i tried to use it without my glasses. I was very shocked to figure out my sight with the vr on and off is the same. Without my glasses things look blurry and fluffy as hell. But with glasses i can see fine. You would think that because the things giving you the picture are right against your eyes and you wouldnt need the glasses. But you do need the glasses. And it blows my mind

[@blandgreen4135]

Hmmm i guess this is why my dad says he can't see anything with the headset on. I just assumed he would be fine without his glasses because of how close the screen actually is.

[@user-jg5oe9bd6t]

Same! I figured since the screen is right up against your face I wouldn’t need glasses but once I put on my headset I couldn’t see anything. I put on my glasses and wow everything was clear! It’s crazy how that works.

[@cottonproductions]

It sounds like this game isn't designed well for 3d if the convergence is so bad on the helmet gauges. I did 3 demos with the Vive and had no convergence issues or eye strain at all but didn't play this game. The 3D was very comfortable and natural. Nothing in any of these games should ever really cross into negative 3D space like in a 3D movie so a lot is up to the devs.

[@Morawka1]

[@mazmusicornament525]

its quite obvious in my situation. i have myopia. never did when i was younger. used the pc alot every day young. when i was younger, i could use pc longer without eyestrain. now it takes 1hr-2hrs for eyestrain, a bit less if i use blue blocking glasses.

I feel for this dude commenting on an old crappy CV1! I'd be interested what he thinks of a modern headset. And soon (~5 years) we'll have production holographic and liquid lenses that can physically change DOF and create real depth.

[@Anticleric]

I really don't understand how Adrift made it as a launch title and why Oculus pushes it so hard. Yaw rotation, taking camera control from the player and convergence are all major issues in VR. The made me make changes to Technolust because of reported convergence issues with lense flares and objects being too close to the player. Seems like it's find if Adr1ft does it though.. *shrugs*

[@VirtualrealitygingerOfficial]

Yeah I'd take Technolust over ADR1FT any day - honestly. Not just saying that because I'm interviewing you soon ;) I was really looking forward to it before my Rift arrived, but once I played it on the live stream, I felt pretty "meh" about it and haven't gone back to it since.

+LordNapalm Indeed. Our game was refused early access yet the shit that gets put on the store is fucking terrible.

[@robertweekes5783]

9:00 I’m pretty sure it’s not blue light but the UV (ultraviolet) light that damages eyes over time. Blue light is known to wake you up so some people avoid blue light at night, and there are monitor programs can turn your monitor to a warmer redder color at night

[@mjherge]

Blue light inhibits melatonin secretion. Melatonin is protective (anti-cancer, etc.) and puts you to sleep. One study found people who wore blue blocking glasses for four hours prior to bed had 30 min more sleep on average. 60+ year olds suffer cataracts which block light, somehow inhibiting melatonin secretion, and decreasing sleep duration in older adults. Cataract surgery is known to improve sleep.

[@VRIceblast]

If your at work, sawing at a screen for 8 to 12 hours, you need to lower the backlight of the screen, and use a much bigger monitor, so everything is naturally bigger, and very easy on the eyes. I saw a screen all day long, and never have issues with my eyes.

[@affecttheeffect]

I recall from college physics that electromagnetic energy is proportional to its frequency which is why blue light with its relatively high frequency has a high energy among the visible light colors. The only thing that puzzles me is why violet has an even higher frequency and hence energy; one might wonder why combining a relatively low frequency red with a high frequency blue yields an even higher frequency violet. I guess that's the way the waves add up! It was interesting to hear Mark talk about how the high energy of blue wavelength relates to the blue light we see every day. Great interview Ian and thank you Mark, your comments were most enlightening! - Pete

[@VirtualrealitygingerOfficial]

Thanks for adding to the conversation, Pete! I'm really glad you enjoyed it - thanks for watching!

[@affecttheeffect]

+VirtualRealityGinger Oh you're welcome Ian, I think I found the answer to my question. It turns out that while purple is a combination of red and blue, violet is a unique color; as such violet has the highest frequency and hence energy of all the visible light colors. Very cool, 'er I mean hot! :-) -Pete

[@RuberSocks]

because purple is darker than blue

[@RuberSocks]

StormShadowGFX wut

[@Martianbuddah]

The response may be a little late but whatever :D ... No, if you superimpose Red and Blue light you will not get higher frequency photons. Your brain interprets the superposition of those two frequencies as Violet, but the photons do not carry a higher amount of energy. Our eyes are not a spectrometer, so what we see is not necessarily what is physically there.

[@427Nut]

I don't get anything negative when in VR. I have an HTC Vive and have been playing since last September. There are a number of settings that need to be set to properly use VR (especially with Vive) but nothing so far. I play an average 1 hour a day during the week and 3 to 4 each day on the weekend (great bow/arrow game and I've lost 20 pounds due to the exercise). If this optometrist is saying his eyes are converging as soon as he put the set on, it's not setup properly for him. We are all different and if I let someone else play my system, it has to be re-adjusted for them. I can tell when I start losing focus and I re-adjust the lenses and things get back to normal. Actually, I just had my annual optometrist visit just three weeks ago and he also did a field view test (due to a medical condition...tested every two years) and then we had a very good discussion with VR. He said he hasn't heard anything bad about VR but there are people who shouldn't be using this...it's not for everyone obviously. My vision is great, no headaches, no strain and no loss of near vision although I need glasses to read but that's due to my age. I'm an old-Big-kid playing games :) For those who want to try...look up online for shops in your area that provide play time for 30 minutes using VR. They are propping up everywhere.

[@Neceros]

[@gargoyled_drake]

[@tehf00n]

I had 20/20 vision. My near sight has become wrecked in the past year. Funnily enough I have been developing with the Rift for the past year. Co-incidence?

[@VirtualrealitygingerOfficial]

+tehf00n Yeah, my understanding based on what Mark and I discussed is similar to what he says around 7:47 when I ask him about permanent damage. He talks about how people that do a lot of computer work needing a prescription to see their computer screen. Make sure to give yourself breaks every 15-20 minutes, even if it's just lifting the headset up and looking out at something in the distance for 15 seconds. It's a huge courtesy to your eyes and helps prevent needing vision correction in the future.

[@tehf00n]

VirtualRealityGinger I tend to take breaks when I smoke but im giving up. Needless to say I am very dubious about long term use of the Rift now.

[@madigorfkgoogle9349]

what is your age? I work with computer for 35+ years now, starting with very bad screens. I started to develop problem to see close up things at second half of my 40s. Now I use PS VR, I somehow notice a clearer view on short distance. BTW I had better then 20/20 vision.

[@laur-unstagenameactuallyca1587]

@Abhinavv Arora where does one go to measure pupillary distance??

[@ca1ib0s]

I think I heard the close up convergence strain is because the brain is used to having to converge the eyes to look at things close to the face but in VR everything is at the same focal distance. (infinity for Vive and 1.5m for Rift afaik). So the brain makes the eyes converge for the close objects and because they are actually at 2m focal distance, the eyes converging cause it to see double. The eyes deconverge to 2m to bring these close objects to focus but instinct and decades of experience of the real world make them converge again etc. This fight against instinct/autonomic focusing back and forth causes the eyestrain when trying to view close objects in VR. Once we can train ourselves not to converge and refocus in VR then that type of VR eyestrain will disappear. permanently

[@VirtualrealitygingerOfficial]

Very interesting insight! Thanks for sharing.

[@scythelord]

+ca1ib0s Rift is infinity. Only DK2 was 1.5m.

[@batvenio3533]

I've got oculus quest 2 the last week. I played few demo games and watched 3d videos. When I play games for 20 30 min i got tired and my eyes get tired. When I watched 360 videos I feel not well at all. The focusing all the time between the distance I can't see the objects near at all. They are buried and make me fell bad. About the games I played the saber beat and is ok i don't have problem but it makes me very soon tied. When I was watching some movies trailers on the app amazon prime video vr in the menu I see and feel well but when watching movie I start to feel discomfort and i don't think that can watch a hole one and half hour movie on the head set. I will return it and continue to play and watch movies on my pc monitor. Ps I didn't return it and got use it. Very nice 😊

[@henriquesantos.official]

did you return quest 2 or do you feel better now and are you with him?

[@TropicalCyc]

You obviously get more tired doing something physically demanding than just watching something that doesnt need any depth and looking at near objects. Because 360 videos only take images in 1 perspective, no depth perception. Also, i get the feeling that your using the default facial interface, if you get a better interface, viewing things in vr for a long time will be more comfortable.

[@paulpjr3224]

To me VR makes me tired. I play right before bed and can fall asleep pretty easy. I feel the screen door effect makes your eyes strain more. I feel they should have waited until it was on 4K resolution. It would have less screen door effect and keep your eyes seeing it clear.

[@cole1396]

[@kairon156]

One question I want to ask now is. Can VR help with eye strain and give people's eyes some further away objects to focus on.

[@CyberWolfVR]

You should of asked him the question, why is it that some people that wear glasses find that they don’t need them in vr, why is this and even if you don’t need glasses in vr, should you wear them? You should have asked this question while you had the opportunity. I would also like to hear his opinions now in 2022 whilst using a quest 2 as it has more pixels per eye and less screen door effect then the rift.

[@ingenious4t]

Very Interesting hearing the experts point of view, kinda puts your mind at rest to know you're not causing any permanent damage (for now). I get minor headaches and the obvious dizziness but other than that, it's all good. Hopefully any negative effects will be addressed as the medium progresses.

[@VirtualrealitygingerOfficial]

Definitely just make sure to give your eyes a 10-15 second break every chance you can! I usually lift up my headset and look off into the distance every time a splash screen comes up, just in case :)

[@howardlam6181]

I want to know whether the mobile phone version does the same. Does it have the same infinite focal distance as well?

[@sdqsdq6274]

well i not gonna take his word for it , a expert in the field doesnt mean he's good for his word , VR has been around for sometime , but now it hit the gaming scene , probably would be seeing more intense gaming onwards , which only time will tell . there are already dumb dudes who died from gaming .

[@mazmusicornament525]

when the doc mentioned convergence, i didnt understand, but his explanation made sense. Try putting a picture right up to your face, almost touching your eyes, now try look at all the details. It feels weird and fuzzy sometimes, definitely bad for the eyes. if you get a vr, most maybe like 30 minutes, but not often.

[@howardlam6181]

Mazmusic Ornament Then you didn't really understand. It's not a picture right up to your face. It's all the graphics are on focus on the infinite plane (super far away) despite some of the objects looking like they are up close. This confuses your brain and sends to wrong signal to your eyes and your coordinate system.

[@jaynj908]

[@nvembrace]

Thank you

[@itzdukey3886]

The max amount of vr I can play every time is around 30 minutes. After that amount of time I either take a 5 min break or i turn it off

[@michaelbaumgarn4733]

i can do 6 hours every day

[@Wolfox360]

In this video they chose one of the most uncomfortable games on the Oculus. And about the Blue spectrum, I think that Blue color is also the one less brightened because in amoled displays is also the color with less time life

[@VirtualrealitygingerOfficial]

The idea was to put him in one of the most uncomfortable games to discuss if, when at its most extreme, VR is damaging (which in his professional opinion, it was not). If I had just put him in a typical game where the eyes don't do anything to compensate for the visuals being presented by the headset, it wouldn't have been a very interesting/insightful video.

[@kontrolmand4657]

its still brighter

[@whatsupbudbud]

Some studies have shown that outdoor light reduced risk for myopia. I wonder if it's related to the blue light or not. I think the benefit was high-intensity light exposure that provokes some kind of chemical production in the eye that, in turn, prevents or slows the eyeball lateral growth. Anyway, check it out: www.sciencedaily.com/releases/2016/04/160406124740.htm

[@fsp48]

Would I be wrong to assume you did adjust the settings to his personal needs?

[@VirtualrealitygingerOfficial]

Nope - you'd be correct in assuming that. The Rift was adjusted to fit him, and IPD was set to match his.

[@fsp48]

+VirtualRealityGinger so it really comes down to the game's 3d design, programming and rendering as to what is seen. Everything I've played so far on my Dk2 has not given me any eyestrain. I have played Eve Valkyrie, Project Cars and E.D. Horizons for hours without breaks as well as the Lab on Steam VR. Part of the amazement when ruining these experiences is the fact that looking around at every little detail just looks so natural to me like I'm really in that rendered reality. Thanks for the video to get perspective and observations from someone who is in the vision field.

[@fsp48]

+fsp48 *running...not ruining. lol

[@VirtualrealitygingerOfficial]

+fsp48 Yeah none of those gave me eye strain either, which makes sense given what Mark says (about distance not being difficult or strenuous to see). It's pretty much only close up stuff that gives eye strain, due to the extreme convergence. Or at least that's what I picked up from our interview.

[@DMan-ud6bt]

+VirtualRealityGinger Yea, I've been playing games only in 3D Vision for the last several years and I would even say that is also the case with the 3D Vision glasses and monitor setup. Can't wait for my Rift to arrive!

[@Gorilla_Jones]

VR will turn out to be like the glasses holders from the movie The Jerk. Be warned, VR is going to destroy your vision.

[@slapthekillswitch]

yeah thats not true

[@cole1396]

Be warned, stupidity is going to destroy your social life. VR will not destroy your vision...

[@yeahhoko1066]

All i want to know is Is htc vive vr bad for you?

[@heyguyslolGAMING]

Thx for the vid. I've been greatly concerned to get into VR due to vision concerns. With that said I think I will try to do no more than 2 hour VR sessions with 2-4 breaks during that time and only a few days a week. I seriously think doing VR for several hours at a time on a daily basis could cause some serious issues as I ran into eye focus atrophy issues a few years ago for sitting at my pc desk without taking breaks and this is even worse as its within a couple of inches. Imo use VR in moderation.

[@OfficialHyperscale]

Nice video!

[@VirtualrealitygingerOfficial]

Thanks! Glad you enjoyed it :)

[@mygoldfishrocks]

I really wanted to watch this, but the guy said "ugh" so many times, I couldn't watch. Darn Toastmasters for making me aware of this!

[@kaminoyami5776]

Why when I fall in the game my body also fall a bit

[@pavankolamkar7310]

my head pains after i use vr for about 5 to 10mints.Y is it so?plz reply

[@Rossilaz58]

Power through, you'll get used to it.

[@1.1-z9d]

Is the vr's advanced as the SAO vr

[@cole1396]

2 years later, no. Probably wont be like that until the next decade, who knows. But is VR still worth it now, even though its not like the unrealistic fantasy that is SAO? Yes, most definitely.

[@owensrebellion]

Couldn't VR actually help with gamers eye sight, because your consistently looking around moving your eyeballs using the muscle's while staring at a monitor you muscles get weaker?

[@holdmyex6893]

so does it mean its more harmful than normal visoion on a video game???

[@bluefelcon]

This person IS NOT A MEDICAL DOCTOR. He is an optometrist. In some part of the world, Optometrist carries the title doctor via "Doctor of Optometry" but they are not medical doctors. They may have some medical knowledge related to their field of optometry only. I would advise amending the thumbnail to avoid such confusion. I am a doctor with a registrar post in diagnostic bio medical imaging. The major concern of VR is the neurology effects rather than ophthalmology effects. In fact the the eyes only transmit the information to the brain via the optic nerve and optic chasm. There is no short term ophthalmic side effects noted yet. Though there have been concerns of long term conditions (eg, cataracts) due to the distance of the screen to the users.

[@VirtualrealitygingerOfficial]

I'm not sure where you're from, but this was discussed at length in the Reddit post when this video was created. In the United States, although not MDs, optometrists are absolutely physicians and held to the same medical standards within their expertise as medical doctors are in theirs. To start your comment off, "This person is NOT A DOCTOR," and then imply that this is fraudulent in most of the world, even though the medical requirements on ODs is VERY different in other countries than where Mark is a practicing physician - you're spreading the very level of misinformation that you're attempting to prevent.

[@bluefelcon]

Fair enough, i ve double check with U.S doctor tittles. indeed optometrist are given dr tittles via " Doctor of Optometry". My apologies then.. In the UK the title doctors are quite restricted to avoid confusion with medical doctor vs non medical doctor. Ill amend the above post but will still state that he is not a medical doctor as in some parts of the world assumed doctor = medical doctor.

[@VirtualrealitygingerOfficial]

I appreciate that. This is something I was completely unaware of going into this video too, as ODs are referred to as "Dr. ______" universally in the United States. I'll make sure to strictly stick to "optometrist" for future videos, to avoid international confusion.

[@kestrelite]

Why does the audio sound like it's from 2003

[@freddylazo7496]

It makes dizzy

[@narutovans7914]

Does the vr make you more blind

[@bucheronix]

Too bad we didn't see his reaction after he took the headset off.

[@jsa2001]

Ive just put an emf meter to my Oculus headset and its reading very high even the oculus touch is reading very high, so im getting rid of oculus.

[@mop0014]

jsa2001 you’re insane 😂

[@mop0014]

@Nagens faggens nope, just enjoying my games 😊

[@mop0014]

@Nagens faggens of course you can question it. But anyone who does 5 minutes of research can find out that there is nothing to worry about.
