Awesome to hear that this worked for you and that you’ve now fixed your eye strain! Your method didn’t work for me though, it seems my eyes really quickly adapt, leaving me almost no time to think what’s happening. However you inspired me to mess around some more time and I can now say, I’ve now cracked it too!! Here’s my solution:
First I messed around with the hardware IPD slider. My goal was to get sharp image in both eyes. What happens is that if one of your eyes is too far away from the lens center, the image gets blurry in that eye (because the edges of the lenses are blurry). So I focused on an object maybe 1-2 meter in front of me and then moving that object a bit and alternate looking through your left and right eye and and try to maximize the space in front of you that you can see sharp with both eyes. My IPD is 69.5 but I ended up using 66. So if you’ve done this part correctly you now have very clear vision, although you might still experience eye strain. So the most important step is the next one, to fix that:
in PE, go to the software offset sliders. First let’s do the horizontal offset. Decouple both sliders, and just move the first one to the left extreme, or maybe to -5. Now use one eye to aim at the + button (with both eyes open it will be hard). Once aimed at the button, open both eyes, (keep your hand steady of course) relax your eye muscles and then start increasing. Relax your eye muscles, so that the image will be garbled up, you’ll see double, and focus on the circle of the slider. You’ll actually see two circles now because of the double vision. Try to have your eye muscle totally relaxed and then keep pressing the +, you will then notice that the two circles (in your double vision) will start to get closer and closer. Just when they touch each other, notice the number. For example Let’s say this happens at -1.2. Then move the same slider to the positive extreme (or maybe +5 is enough). Relax your eye muscle again, start decreasing, while focusing again on that circle of the slider, you’ll see 2 again and while keeping your eye muscle relaxed, keep decreasing until the two circles kiss each other and notice the number. Let’s say this is + 0.6. Now do this several times to make sure your numbers are correct.
At times you’ll accidentally focus and your double vision will be gone, so then just increase the offset again (further away from 0) until you easily see double again and then relax your muscles again.
Also do notice that the more your eye muscles relax, the circles will drift slightly away, further from each other. So it’s important to do this when your muscles are totally relaxed.
If you’ve done that, simply take the average of the 2 settings and that’s what you’ll set it to. So in my example -1.2 + 0.6 = -0.6. Then -0.6/2 = -0.3, so you’ll set it to that, since -0.3 is exactly in the middle of those two.
Then do this for the other eye too.
After that do the horizontal offset. Decouple the sliders. This time focus on the slider horizontal lines. If you set the first eye to for example -5 you’ll see double, then start increasing until the lines are aligned, notice the number again, Then do it from the max, start decreasing, notice that number and take the average. Then do it for the other eye and set it again to the average.
This really fixed my eye strain. In fact I now have razor sharp image, MUCH better 3d effect, way better immersion and everything just looks and feels so much better now! In fact, this now feels like a whole new headset and I can honestly say it’s now the first time that I’m REALLY enjoying the 8kX-!
BTW, it’s probably best if you do this step 2 with an object (the lines/circles) in the distance, since that’s where you won’t have double vision in real life with eye muscle relaxed. I didn’t set it that far away though and it seems to work perfectly, but I’ll try and tweak it some more. Then again, I’m already really happy with the result, this really feels like a new headset now!
