After-effects of using Oculus Rift

Maybe someone's mentioned this before. I've been using the Oculus Rift for about a week now, and I notice that when I'm not using it, or even the next day after using it, that my vision occasionally dilates (not sure if that's the right word) or kind of squeezes, as if I was looking through the head set.

Does anybody else witness this kind of effect? In particular, I'd like to hear from someone who's been using it a bit longer, if maybe the effect continues or improves.

  • You're probably just noticing yourself focus. When using the Oculus Your eyes are focused out to infinity. Your eyes don't have to turn inward to look at something closer to you. When you take it off your eyes then have to focus again because some objects won't become clear until your eyes turn inward to focus. This would technically also slightly lower your personal FOV.

    You have a great opportunity here.
  • Havnt heard of this issue yet my friend.

    I've had it for all most a week now and noticed that if I'm in the rift for 30 minutes +, when I take it off my eyes have a really hard time focusing. Doesn't last for longer then 15-20 minutes but I don't get sick or anything at all. I watched avatar in 3d using the rift the other night and that is about 3 hours long when I took off the rift my eyes felt really fucked up I went to sleep because it was late but when I woke up everything was fine again. I'm just happy I'm not one of the people that get sick using it, playing First law and delta draconis is really fun and if I got sick it would really suck. :lol:
  • Hello Draemn03 (and to anyone else, this is my first post on the OR forums!)

    I have to agree on the eye's-shifting focus after long use of the OR, I got my Rift last Friday, and have done nothing else but tinker with it. And after starting Fallout 3 over again (TriDef are AWESOME) I've been having 2~4 play sessions, so far my longest trek with the Oculus on without it being removed was about 3 hours. Afterwords I noticed my eye's tend to lose focus more often. Watching TV, i could tell that my eyes were having a hard time looking at a 2D screen after so long in the Rift. Whats even worse is that the projector (during lectures in class) is harder to focus on after using the OR, no idea why maybe i just have really bad eyes or something. I honestly dont know much about how the eyes focus and what not but Just thought i would share my similar experience.

    I have a similar problem with this. When I use the Rift for more than a few hours, my left eye (my worse eye) has extreme problems focusing for the next few hours. I think it has to do with the fact that I don't wear corrective lenses, and the lenses require different focus points for each of my eyes, causing the left eye to over adjust.
  • I wanted to add that I also experience the same thing. My eyes seem to focus/unfocus quickly or at random after a few hours in the Rift. It lessens after a while, and I'd imagine it would go away if I could ever stop using it!

    What got me though, I played one session after feeling exhausted (I was about to go to bed, but didn't) and played some WW2 plane game that actually made me really sick. I immediatly turned it off, but when I went to lay down I felt like I was still falling. My inner ear was off for about a day or so...
  • I've been playing Half-Life 2 with it (actually my first time playing it, so I kind of get the full experience of it with the Rift). I've definitely been playing at least a couple hours at a time per day, probably 3 or 4 hours the first day I started. I don't get nauseous at all as long as the head tracking is smooth and as long as the images are converged well. It just that my eyes will occasionally shift the next day while I'm work, not terribly though.

    Yup, same here. It feels the same as using the rift when moving the head for example (still after about 4 hours after using it). I think my brain tries to adjust to it.
    But I am only using the rift for 2 days now, so pretty fresh here.
  • GanjaroachGanjaroach Posts: 449
    So is their anyone that has had the rift longer then a few weeks still have the focus problem? I'm wondering if this is something we can get use too or will it all ways happen?

    I've had similar effects, and I kinda enjoy them whilst my primate brain is finding a way to compensate.

    I call it Oculus Rift Cessation Syndrome (ORCS). 8-)

    I have to say I am a bit scared by the after effects of using the Rift.
    After 3 days here is my list :

    -Small but constant feeling of light head and vertigo even hours after using the Rift

    -Feeling of still being on the Rift, mostly for the tracking, few hours after using the Rift

    -Eye Strain for hours after using the Rift only a couple of hours (but not worse if used more)

    -Having hard time to focus on small text and information for hours after using the Rift

    I hope my brain will adjust in the RIGHT way... otherwise I'm a bit scared by what could happen.

  • I guess one benefit of still not having my Rift is that I can let you guys test out the short term affects of using it :)

    I'm noticing some similar effects, but they seem pretty mild so I'm not super concerned.

    For the vision issues, I think it has something to do with having a mild lazy eye (never diagnosed for me, but now all of sudden after using Rift I'm aware my right eye is weak). In the rift the lazy eye is doing different things than it is used to in real world since everything is in focus on the rift. The right eye now only has to worry about aiming in the right direction to get a converged image. My theory (er...hope really) is the rift is helping fix my lazy eye! No way I'm going to stop using it now. :)

    I don't get motion sick at all, but for the motion issues, I spent a week on a ship and for 3-4 days afterwards I felt like the world was swaying. It didn't make me sick, but it was something I noticed. I think Rift can have some opposite motion effects that could last due to disconnect between ear and eye.

    feeling of still being inside the rift? sounds like some people might go insane because they cant tell
    the difference from vr and real life :shock:

    doesnt sound healthy this topic :(
    honestly im gona stop using it for a while because i dont have a good feeling about it.
    im just gona observe here for a while what happen after long term usage

    I had the same feeling - only lasting for about 15 minutes after using the rift for an extended period of time (over 40 mins) - where when I moved my head my vision took a while to 'catch-up' with what my head was facing (a few milliseconds). It's exactly like the latency effect when inside the rift. It's almost definitely the brain compensating for this delay. Moving my eyes had no delay effect, just moving my head.

    It doesn't seem to happen any more though, this just happened in the first few days of having the rift.

    No I don't think you understand what I meant... Of course I can tell the difference between being in the Rift and in reality...

    This is what I meant...

    Also, since I played with the Rift two days ago I feel dizzy, I have nauseas, trouble focusing my eyes, I feel exhausted and I have eye strain. I didn't touch the Rift since then, but the effects are not leaving. I am a little scared...

    Folks, we need more information why just you get this symptoms,
    like whats your age, do you wear glasses, using drugs or alcohol and so on.
    otherwise this thread makes no sense.

    I'm 44 and never felt anything similar after using the Rift,
    i dont wear glasses btw. but a few drinks here and there :lol:

    The symptoms you guys are having make me think there is some de-synchronization going on between the vestibular system and the visual system. I imagine this would probably go away the more your brain gets used to the rift, although different people might take different lengths of time for the effect to go away (hrs vs days vs weeks). I'm going to ask a friend of mine who is a neurosurgeon what her thoughts about this are.

    I want to preface this by saying I am not a doctor, or a medical professional of any type, so this is "just some guy on a forum" here, but if it makes you feel any better I am a decently educated guy on a forum :P

    It sounds like, at least to some degree, it may be psychosomatic. Again, not a professional, and kind of impossible to make a judgement call on a forum, but you seem to be so concerned the anxiety could be making things worse.

    There is absolutely no reason to believe you have suffered any sort of permanent damage, the only history of staring at a screen causing any sort of damage that I am aware of is epileptic seizures caused by flashing lights or alternating colors. And as stated above me, any sort of disconnect or dizziness should disappear over time with use as long as you don't over do it.

    If you are that concerned about it you should go to a doctor and put them to rest rather than worrying about it and letting your anxiety over the unknown get to you and potentially making any problems you have worse, or even possibly causing them to begin with.

    I started getting worried after these two days. I was thinking that the symptoms would leave, but they didn't, at least not before a long time (I am starting to feel better).

    It can't be coming from my anxiety since I started having anxiety a long time after feeling bad.

    So, I asked my surgeon friend about this and she told me something interesting. When she was training to use a robotic surgery system, whenever she finished her sessions, which consisted of looking through a "VR" type setup (I'm assuming its the DaVinci system) she would feel spaced out and weird for hours afterwards. One of the things she told me is that she had problems using her phone because she couldn't focus on the screen. This side effect went away 2-3 weeks after starting the training. But here's something interesting: She says if she doesn't use the robotic system for a long time, she gets the side effects too when she goes back to using it. So she plans for training sessions a few weeks before she has an upcoming robotic surgery.

    really eye strain is expected of anyone,
    simply because you are trying to focus on something that "feels" like it is far away but actually very close to you,
    it does take a while for the eye to adjust to it,
    but depending on the person, it may or may not take a long time,
    however tho, there hasn't been a study on the long term effect of being in something like this,
    if it turns out that the long term effect of wearing VR goggle is substantial, it might just be the death of screen HMD
  • Losing focus after using the Rift is not a problem. The eyes need to refocus all the time. In fact, most likely, this problem is because some people don't change the distance of what they are looking at often enough. Still, you should limit the time you spend in the Rift based on how much of a problem you have with this.

    If after using the Rift, your eyes seem out of whack, just look at things at different distances until you can focus, do it until it becomes easy.

    As for the motion sickness, if I remember correctly, it should be solved by simply looking at things that are not moving in relation to the person. Accelerated by reaching out and holding the object from moving in any from the person feels will work. Move to a new object when your sure the last is not going to move. As silly as it sounds, the entire point of higher reasoning and logic is to relate many things, so when they are moving around randomly this destroys this and the person can convulsively try to hold them still. The sickness is induced when the person tried to keep something from moving and it repeatedly moves anyway. The person will always be found to have the mental strain to stop the movement. A heavy strain ensues due to a conflict of different regions in the brain making a headache as well as symptoms of a non existent illness the result. (I can only guess that our ancestors once had a problem with this in the form of a virus, poison or other illness and a full on attack with the immune system was the cure? Example, if you got drunk enough and the room spins, often the person will vomit.) Whatever the cause, it is just as easy to calm as it was to get started.

    I felt a bit of light-head after around 5 minutes in Rift for the first time. The slight dizzines remained for about an hour after taking it off.
    I went back in again in the evening and this time it was MUCH better. I was trying demos on and off for 2 hours and didn't feel anything after. Today however I feel small constant feeling of light head. Nothing worrisome, but it's there and I decided I won't "jacked-in" till evening.
    Anyway, LOVING my Rift! I'm so happy I decided to get it early on :)

    -Small but constant feeling of light head and vertigo even hours after using the Rift

    -Feeling of still being on the Rift, mostly for the tracking, few hours after using the Rift

    All of the above.
    What I do notice is a mild feeling of being "disconnected" during some parts of the day. As if I'm not really there. Luckily it just lasts for a split second and then it's gone.

    I did some research and there have been some studies on the psychological effects of VR which had some interesting findings:
    "Source
    Fernand-Seguin Research Center, 7331 Hochelaga, Montréal, Québec, Canada. faardema@crfs.rtss.qc.ca
    Abstract
    This study utilizes an innovative experimental paradigm to investigate the effects of virtual reality (VR) on dissociative experience and the sense of presence. A nonclinical sample of 30 people were administered measures of dissociation, sense of presence, and immersion before and after an immersion in a virtual environment. Results indicate an increase in dissociative experience (depersonalization and derealization), including a lessened sense of presence in objective reality as the result of exposure to VR. Higher preexisting levels of dissociation and a tendency to become more easily absorbed or immersed were associated with higher increases in dissociative symptoms resulting from VR immersion. Results are discussed in terms of imaginative processes underlying the dissociative experience and potential implications to the treatment of anxiety disorders with VR."
  • I tried my friends rift for only 20 mins or so, and I am getting my own tomorrow.
    But I had some nausea for a whole day, felt better next morning but eyes were still tired.

    Need to play around more when I get my rift.
