focal distance, distance from eyes and lens power of quest pro

can't find information about power of optical lens, focal lengths, and distance from eyes to opti lenses used in meta quest pro.  for example, it says focal distance is 1.3 meter and some says 1.5 meter.
 
I need these detail dimension for developing VR content and maybe the following optometry applications.  Is there anyone can help?

The Quest 2 is 1.3 meters according to John Carmack's Tweet (I mean X).

I don't think anyone has made a definite statement about the Pro, so in lieu of someone from Meta chipping in... I'm using both headsets, regularly swapping between the two, and they seem to be identical to me. I'm short-sighted and use a specific pair of glasses in VR and I tend to notice when something has changed. The Pro has eye relief adjustment, not sure if that affects overall focal length (it doesn't seem to).

Would be good though if Meta can confirm.

Distance from eyes to lenses (eye relief) is different for everybody depending on the shape of their face. Plus headsets like the DK1, DK2, Rift-S and Quest Pro have variable eye relief adjustment with no sensors to measure it (I used to pull it close enough that my eyelashes touched the lenses, so I'd get maximum FOV).

It might be possible for an app to measure eye relief by testing how much the user can see (lower relief reveals more of the screens), there's just no fixed universal value for a Quest Pro.
