IPD basics for XR display glasses
IPD is the distance between your pupil centers, in millimetres. Display glasses have an eyebox: the zone where each eye sees the full, sharp image. If your IPD is far from the design, an eye sits near the edge of that zone.
Measure it
Your optician's prescription may list PD. Or use a mirror and a millimetre ruler, closing one eye at a time. Phone apps vary in accuracy.
Most display glasses have no IPD adjustment
The eyebox width decides fit; RayNeo, for example, publishes eyebox dimensions for the Air 2 and Air 2s.
Near the edge?
- Nose pads shift the eyes vertically, which can still help.
- Per-eye horizontal alignment in software moves each image, which can ease fusion, but it can't enlarge the eyebox.
