😶All just wanted to let everyone know especially those we glasses there's an issue where we need to be mindful not to over do VR usage.  Seems obvious but for me I found bags forming under my eyes and fatigue more than I should after flights.  I don't feel I was using the headset for lengthy amounts of time and certainly didn't have issues to this extent with the Reverb.  There may be an undiscovered problem as we get more into high definition headsets with screens so close to our eyes. There could actually be a long term problem that only more advanced lenses can solve.  The lenses in the Cystal are amazing especially the clarity.  This may also be an issue where until I got things dialed in serious eye strain could occur with wrong IPD settings, wrong graphic settings, jarring scenery paused when turning my head, etc.  Many of us were waring the headset wrong among a host of other things.  To add insult to injury, again these screens sit inches from your eyes and this is a new technology.  Can this cause long term damage to your eyes, we don't know yet.  I was in denial because I didn't want to go back to a pancake screen with MSFS.  We all know there can be eye issues with regular monitors if looking at a screen too long let along a VR headset with the display right next to your eye balls.  We all are different but I thought I'd post this to bring awareness.  We only get one pare of eyes.  Here's a write-up I found:

VR eye fatigue and straining are induced by a similar body response to staring at digital screens. Users often report discomfort, sleepy eyes, and even headaches after long VR sessions. Other symptoms include blurry vision, itchiness, light sensitivity, and trouble concentrating.

The bags under your eyes could also be from wearing the headset too tight, and or for too long. I wear mine loose and let most of the weight sit on the top strap, otherwise it starts to irritate my skin and leave puffy bags under my eyes. 

The blue light in displays is also horrible for your eyes. Especially for your circadian rhythm if you're using it in the evening.

There are Eye Mobility exercises you can do to revitalize your eyes.

Most of my flight are 30m to 1 hour. Anything longer and I get bored anyways.

The good news with the wired CL, there are no radiation hazards! That was a big selling point for me!

I use the third party padding with my headset.  The padding that shipped really irritated my skin.  Are you using the padding from Studio Form Creative?  My flight time is actually shorter than yours, usually 30 minutes at a time.  

To your second comment you're talking about using the headset in the evening within MSFS, correct?

I am using default padding.

Yes to your second comment.

I'm still experimenting with the IPD adjustments but yes, at the moment I feel eye-strain at the moment more/sooner than in the past and so have limited my time span.  That said, the correct IPD, and the repeatable correct sit of the headset on your face, is important with all headsets and I do remember fiddling around for sometime with the G2 and the Pico 4 when I started using those.  I also remember starting off with relatively short sessions at first with them too. 

However, probably because of the sharpness and type of lenses, the Crystal Light does feel a little more sensitive to even small adjustments than my previous headsets.

The other thing I'm not sure about is the absolute, rather than relative, accuracy of the IPD reading.  I say that because I know my accurate IPD from my recent eye tests and, actually, that setting isn't the clearest through the headset.  Instead, I find usually that one lens is a touch blurry and so I have experimented with adjusting it visually (which, for me, ends up with the lenses a mm or so closer together).  With the replacement left lens now fitted I have some further adjusting to do so will carry on experimenting with finding the best adjustments for me.

You might want to check out Studio Form Creative's padding and headset weights.  Really makes a difference in comfort.😉

You are laughing now, but you will be crying later, when you're dying of Cancer. No worries, the corrupt Healthcare Industry will be happy to take Your Money. Their long term success rate is less than 5%. 

Do you really think the revolving door between the Industry and the Captured Regulators has your best interest at heart?

Thanks for the reminder! Was going to order a few months ago, but they were out of stock.

Been doing some reading and testing.  It seems 90hz is better on the eyes than 75hz from what I can tell when using the CL.  At first until I started turning off 'Use NANOVG for XML Gauges' with each sim use, 90hz exacerbated the performance issues I was having when heavy clouds were present (I run room lighting frequency at 50hz).  Now I don't have an issue running the headset at 90hz and only in extreme situations like Boeing Field in Seattle in heavy clouds do I use 90hz Upscale.  Not sure what the last Pimax update did but '90hz Upscale' looks allot better now than it did with the first update that broke the IPD headset setting.

The question I have, is 90hz better on the eyes than 75hz?  Can anyone confirm that the higher refresh rate is actually less taxing on the eyes?  I've been looking around for something conclusive on this. Not only does the sim look better in the headset but my eyes don't feel as strained after use.  It would make since but just wondering.🤔

I am no expert, but I know your eyes are going to suffer under artificial lights (PWM(flicker), Blue Spikes, etc... The higher the frequency the better in my opinion. 

A fundamental problem with current VR headsets is the mismatch between convergence and accommodation.  This is a natural reflex; when you look at things up close, your eyes converge and there is an expected change in focus that does not happen in VR.  This causes problems for some people.  There have been some experimental headsets that tackle this with variable focus lenses and eye-tracking, but nothing on the market.  I am quite happy with the way things are because in real life, when things get close, I have to put reading glasses on.  In VR I can read things in front of my eyeballs.  I agree with the above though, that bags under the eyes are probably more to do with padding and pressure.

After testing it seems 90hz feels the most comfortable on my eyes.  Upscaling at 90hz is a good option as well.  Not sure why it makes a difference but that's what it appears to be on my end.🙃

Yes - me too.  It's juddery on taxi-turns at 72 and 120 but smooths out significantly at 90Hz.  I haven't got my head round why yet - I would have thought 90 would have been worse than 72Hz.  

I had my best ever VR flight last night on multiplayer, me flying the Flying Irons' FW190 in formation with my brother-in-law's Flying Irons' Hellcat over the UK at sunset.  The graphics in the Crystal Light were knockout!  Also, it was clear that I could see stuff in the distance much sooner and clearer than my b-i-l using his Reverb G2.
