Odyssey Plus with ED has injured my eyes

Hi All,

An observation/cautionary advice. Hopefully, it's just affected me and no-one else. The plus side up front is that, now I've stopped with the O+ and ED, after about 3 weeks, my eyes have mostly recovered, although I'm back at the Opticians tomorrow to see if there maybe any lasting effect.

I've been playing ED with various headsets over the years, Vive, Vive Pro and, since it launched, the Samsung Odyssey+. I had the original PiMax 4k from KS but never really got that to do anything fun. 3-4 times a week I will be in ED for an hour or so, doing whatever, taking breaks as needed. Then I noticed I had deteriorating ( it seemed ) blurred vision during the day, watering eyes, couldn't read monitors at work, couldn't focus on a person standing more than 4 feet away etc. The whole effect came on gradually over the course of a few weeks but when I realised I couldn't read the number plate on a car 20 yards in front me, I knew I had a problem and the only thing I could think of was the VR headset so I stopped using it.

One week later ( no gaming ):-

No change, couldn't focus, reading glasses didn't help unless I pressed my face up to the monitor for whatever I was working on. Eyes watering most of the time when working. Kept turning my head to try and find a zone of focus in my vision. Waking up in the morning, for ~2-3 hours my focus is completely gone like swimming underwater without goggles initially but eases later in the morning.

Two weeks later:

Eyes had improved slightly. Far vision was starting to come back but I could still see I had a problem. Near vision still hadn't recovered enough for my glasses to help. Morning blur was reduced in both strength and longevity. Can't read any books on my tablet so no bed-time reading for me still. Pity because I'm reading Return from Ringworld - again. Can't get enough of Larry Niven.

Three weeks later:

Morning blur pretty much gone. I can see well enough to write this. Far vision much better but still not where it was. I feel like it's still improving so I'm hopeful the effect isn't lasting but I'll find out tomorrow if there's any impact on my glasses prescription.

With the VR I was always conscious that text in ED felt like I was staring at an old CRT from 2 inches away, although the O+ for me, is better than the Vive Pro. I would spend time changing various settings to increase resolution, e.g. max out SS, HMD SS, even turn up Steam SS to 400% although the combination is too much for a 2GHz 1080Ti.

I even changed all the HUD pixels to green because the O+ uses AMOLED with a pentile matrix for which only green sub-pixels are replicated for all pixels. It did improve the resolution noticeably but not enough. It's interesting that the Vive and the Vive Pro, with the most shocking SDE I've ever seen, never gave me these problems.

I do wish that VRgineers would make aspheric lenses we could use with other headsets so we're not stuck with lenses which zoom in on pixels rather than using most of the panel because I'm not paying thousands of euros for one of their headsets unless my girlfriend lets me sell one of her kidneys.

As for ED, I've tried going back to old style 2D gaming and I feel no immersion, the ships all look the size of a matchbox, there's no sense of scale etc, it just looks like a TV cartoon. Reminds me of how Clive Gringras and Warren Burch killed BBC Elite for me. After watching a wing of police vipers break formation and blow panels of pirate ships in Archimedes Elite, Beeb Elite was just naff. This is how 2D kinda feels for me which is frustrating because VR is still so immature not least because the panels are just not good enough for my eyes :(

I'm contemplating a Reverb or biting the bullet and getting an XTAL but I sense a rather serious convo with my optician first. I suspect they're just going to say that me and VR are done.

Will I listen - not likely...
 
you should have gone to the doctor way sooner.

i'm still not convinced that your issues are entirely related to vr, unless there's something really off with the odyssey plus. i've had larger exposures than that with a rift and never had a problem (and i am old and do have vision issues), a bit of re-adaptation after use at most. wish you all the best.
 
This may a be a case of long term exposure, the truth is there have been no long term studies on how prolonged use over time can affect people's eyes so anyone saying there is no danger is really making an educated guess.

You basically have two mini screen right in front of your eyeballs for the duration of use which IMO can't be that good considering staring at a PC screen or tv for long periods of time is not good either which is why people that need to do this 8hours a day or more at work tend to follow the 20/20/20 rule.

Not really related, but kind of is, I had the last year or so converted from regular lightbulbs to LED lightbulbs but will be switching back as I find the LED bulbs hard on the eyes which led me to googling about it which lead to quite a few articles warning about their use.

New findings confirm earlier concerns that "exposure to an intense and powerful [LED] light is 'photo-toxic' and can lead to irreversible loss of retinal cells and diminished sharpness of vision," the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) warned in a statement.


The agency recommended in a 400-page report that the maximum limit for acute exposure be revised, even if such levels are rarely met in home or work environments.


The report distinguished between acute exposure of high-intensity LED light, and "chronic exposure" to lower intensity sources.


While less dangerous, even chronic exposure can "accelerate the ageing of retinal tissue, contributing to a decline in visual acuity and certain degenerative diseases such as age-related macular degeneration," the agency concluded.

Could be. Maybe my eyes just decided, 'enough'. I did use bulbs with blue colour temperature as opposed to orange or yellow for more natural light but also started reading about damage so that was that. Not heard the 20/20/20 rule but I'll guess it's meaning is akin to, "If I sit in front of my screen all day then I'm an idiot".

When I owned PSVR, it constantly gave me warnings to take frequent breaks. I don't think it's good for us to use any VR rig for hours every day with no breaks, since it's faking a 3D environment using stereovision mm from our noses. If anything, I'm surprised more people don't have screwed up vision.

Someday, when I truly am an Old Duck, somebody will perfect light field displays, and this will be "true" 3D space. In the meantime, be careful!

The rule says that for every 20 minutes spent looking at a screen, a person should look at something 20 feet away for 20 seconds.

Results of a 2013 study involving 795 university students suggested that those who periodically refocused on distant objects while using the computer had fewer symptoms of computer vision syndrome, which include eye strain, watering or dry eyes, and blurred vision.
 
How strange. My eyes went quite bad since getting the SO+ also. Now I can't read the small print on things like tins of beans or the writing on my watch face, this is all in the last 3 months or so. I am 47 so chalked it up to age , but now I'm thinking about it it coincides with when I got the headset.

It's age but I think perhaps excessive use of HMD's make age related problem appear faster or acerbate the problems. It's called Presbyopia and everyone eventually suffers from it.

Presbyopia is the normal loss of near focusing ability that occurs with age. Most people begin to notice the effects of presbyopia sometime after age 40, when they start having trouble seeing small print clearly — including text messages on their phone.

Presbyopia is an age-related process. It is a gradual thickening and loss of flexibility of the natural lens inside your eye.

These age-related changes occur within the proteins in the lens, making the lens harder and less elastic over time. Age-related changes also take place in the muscle fibers surrounding the lens. With less elasticity, it gets difficult for the eyes to focus on close objects.

I am 45 and this year I noticed I was having to hold my kindle at arms length away to be able to read so went for an eye check up and so doc explained this to me. I have to add I think all the LED lighbulbs made this worse as right now I have one LED white bulb in the kitchen and I can't look at the chandelier at all as the LED bulb hurts my eyes but the other normal bulbs don't.

I will be going back to the regular old fashioned bulbs.

Oooh! Cheers @Space Dandy. I'm exactly 40, and noticed this year that holding things a bit close (but not stupidly close) meant I couldn't focus on the words. Several times I've caught myself having to create a little distance when reading something, which I know I never used to do.

Until recently my vision has been perfect. Time to finally visit an optician.

Ya reading the ingredients on canned goods and the like is not possible now without my reading glasses lol...Thankfully my wife says I look sexy with them on!
:LOL:
 
Seems like the eye muscles that are used to focus eyeballs between near and far vision gets weaker with VR headset use due to the screen being right up to the eyes.
Hopefully its not because its a magnifying glass with an led burning/damaging the retina.
Maybe an opthamologist should be asked to take part in developing better/safer ways to make a VR headset.
Its all cutting edge tech with no long term studies.
Its what is holding me back from buying a VR setup.

In VR, you don't focus on the screen right in front of your eyes. You are actually focusing on a virtual image created at some farther distance. I think this was about 6'/2M on the Rift CV1, but I don't know about other headsets. That makes me wonder if some people develop eyesight problems because their eye muscles are working at a distance that they don't usually use that much. I think most people spend most of their time at near distance, reading books, computer monitors, phones, and etc., or at long distance, such as being outside, driving, or even being a couch potato. Conversely, I'd think the extra "eye-exercise" at mid-distance could actually improve vision.

Anyway, in my mid-40s, my eyes took a dump over a very short time, but then grew very little worse over the last 10 years. When I got the Rift S, I found that I started to need an old pair of weak reading glasses to get things in focus. A year ago, on the CV1, I did not. I assume the sets have different focal distances.

Do you still have the cv1? if so do you still not require the reading glasses to see things okay?

While your reasoning may be correct have you considered that maybe your eyesight got just a little bit worse over the course of using the cv1 and getting the rift s is just coincidence?

As to eye exercises apparently it doesn't work, I asked my doc about it. Near sightedness or farsightedness has to do with the shape of the eye and exercises wont help that, as for presbyopia it has to do mostly with age and the loss of elasticity due to changes in the protein due to age which exercise can't really help or reverse.

This is mostly due to the fact our cells can't replicate infinitely without error or loss of information, everytime the cells/dna replicates the telomeres are a little shorter each time which is why we age and eventually die. I believe it's referred to as the hayflick limit or some such.

As a fellow 47 year old I've learned more about why my eyes have suddenly started getting worse.

I'd echo what Space Dandy says about eye exercises, sometimes known as the bates method. Asked a couple of optician acquaintances about this a few years back and their opinion was that normal focussing of short, medium and long distances is more than enough to keep focussing healthy. It might help if you're constantly focussed at set distance, but it doesn't do anything to help with age related degeneration.

For my own experience I switch between the Lenovo Explorer and the Odyssey+ and I find my eyes are more tired after an Odyssey+ session. Comparitively the Odyssey+ display isn't as sharp (probably the anti-sde introducing blur) and it feels like my eyes have to work harder than on the Explorer.
 
So, I was at the Optician yesterday and they reviewed my prescription 3x. My eyes have definitely deteriorated - doh! However, not significantly beyond my last test just over two years ago. She said that, if VR is a factor then it's a small effect. She did the usual retina inspection and said everything looks healthy, not that I was expecting otherwise for that part. Down side is that it's £740 for a pair of varifocals and another pair of reading ( VR ) glasses. Obviously the former won't be much use with a VR focal plane 2" from my eyes.

Really good news; HP Reverb Pro now available in UK so I'm having that. If anyone else wants to torture their vision with the Samsung EyeTrasher+(tm), I'll flog them mine for £200.

When first using the O+ (first-time VR user), I had significant problems in the beginning. But they were not similar to yours. In my case, I lost focus on far away objects in the real world. Things which were close were no problem, but focusing on objects farther away was a real strain. It wasn't blurry, it was essentially double-vision, like when you cross your eyes.

The effect showed up on the third day, after having used VR for just two days, 1-2 hours each day. It would stay for several days during which I tried not to use VR. But in the end, this got on my nerves so much I played Elite in the evenings after all, because in VR, focusing on 3D objects worked fine, making me feel some relief. So VR was fine, while the real world was not. After playing, I would just go to bed, so I wasn't forced to focus my eyes on real-world objects. So, in essence, it was the other way around than what it should be: The real world strained my eyes while VR did not. Weird.

It took slightly over a week for my eyes to adjust, and now everything works both in VR and in the real world, no perceived strain anymore. But this is still a noteworthy phenomenon, that is known (as I've read in VR research after the incident), but not as well-known nor as wide-spread as nausea, which I don't experience at all, no matter how bumpy the planetary surface I traverse with my SRV.

Another initial effect of using VR with the O+ was that it got me tired real fast, and it made me sweat like crazy. It was very straining. I had observed a similar effect - though not to such an extent - when watching my first 3D movie in a cinema. It took several days to adjust to this as well. Seems like my brain was doing some crazy amount of work processing the stereoscopic image in the beginning...

VR - or rather the stereoscopy? - can definitely have some odd effects on the human body...

Get your prescription, do a bit of window shopping then and shop around online to purchase, it’s a lot cheaper than just buying them from the store you got the eye test
 
Started using my O+ again this week but just for short periods.

I've been looking for ways to help reduce eye strain, other than just taking off the headset regularly and and interesting little trick revealed itself to significantly reduce eyestrain for me:

With the O+ the diffusion grid is visible if I look carefully but I also noticed that, if I relax my eyes and keep my head still whilst looking at any sort of pale brown background, e.g. in certain sunlit ring systems, I can see the diffuser quite easily and, with my eyes relaxed, the diffuser is naturally in focus - strange but ok. Doing this for just a few seconds now and again, had the same benefit on my eye fatigue as taking the headset off for breaks. No idea why it works and if it's just me but I'll take it.

Also, I now run SS 2.0 and HMD 2.0. Ok it's laggy as heck but I got over VR nausea years ago so I'll take crappy fps over eyestrain any day.
