Cog-zooks! We've got our gears turning as we remove the eye relief adjustment on the Vive headset.

Not to be confused with IPD, this adjustment actually controls the distance from the headset's optics to your eyes.

The Rift CV1 doesn't have this feature, probably because its asymmetric lenses allow you to adjust focus by simply pushing the headset higher or lower on your face. Is this confirmation of a different approach to optics in the Vive? Only more teardown will tell.
