First of all thank you for this very insightful discussion.
I got here because I too am having trouble with eyestrain and focus issues with the Reverb G2. To (far) lesser extent with the Quest 2 and Pimax 8kx and none at all with the Rift CV1.
My prescription is nothing special:
IPD according to Optician: 63mm (could be a 20year old value though that just got copy and oasted for decades without re-evaluation)
IPD self measurement (various methods, all resulting in the same): 65mm
Going to see the optician thursday to double check my prescription (only got it a few months back).
However I’m observing the following:
A) Contact lenses: -1.75/-1.75
A.1) Sweetspot is minimal and text gets blurry on the left and right columns of the [win key]-Overlay and I’m having a hard time even reading the text outside the center column…
A.2) absolutely everything feels too small in VR. Steering wheel and depth perception (too far) is off by a nudge, but enough to cause eye strain.
B) Glasses (prescription see above)
A.1) Sweetspot is WAY better. I can now read columns 1,2,3 clearly and the falloff is way less pronounced than with contact lenses.
A.2) same as above. Everything feels a nudge too small and eyestrain after a few minutes of use. But better than with the contacts.
C) without glasses or contact lenses:
C.1) I can’t read anything, just as blurry as in real life. Can’t say if clarity falloff is vetter as I can’t read anything (lol), but seems the same as B).
C.2) this is where it gets interesting: absolutely everything feels like true-to-life scale. It’s a blurry mess, but it feels like I could grab the gear stick, steering wheel or touch the buttons on the dash panel like in real life. Depth perception is the same - perfect.
This only happens this badly using the Reverb G2. The Quest 2 feels slightly off too, but I have to actively look for it to become perceptible. With the Rift CV1 I can wear glasses without any negative effect at all. It’s just perfect.
Sooo… Any ideas?
I’m thinking of just getting prescription lenses from VR Optician and try them out, but they currently have a lead time of about 5 weeks excl. shipping.
Also did some background digging into VROptician (TwoSight GmbH). Their CEOs are one guy that has a masters in advanced computer science, the other one looks like he was in a leading role at Fielmann (big German optician corporation and now runs his own optician business in Germany alongside VROptician which seems to be just a storefront for the TwoSight GmbH alongside his actual optician business). So that at least looks like they have experience where it matters and look like not just being some basement business reselling generic 3rd party lenses.
BTT: any ideas what’s happening in A) B) and C)?
