Two terms that are often used when talking about headset adjustments and clarity are “IPD” and “lens spacing.”
IPD stands for Inter Pupillary Distance, or simply put, the distance between your pupils.
Lens spacing refers to the distance between the clearest spots on the two lenses inside your headset.
To achieve the best image clarity, lens spacing should line up with your IPD as much as possible. Quest headsets best accommodate IPDs between 56 and 70 mm, or about 95% of adults.
Finding your IPD
If you're not sure what your IPD is, the best way to ensure the most accurate measurement is to visit an optometrist.
You can also estimate your IPD using a mirror and a millimeter ruler. It's easier to have a friend measure it for you, but you can measure it yourself following these steps:
Stand in front of a mirror and hold a ruler above your eyes.
Closing one eye, line the end of the ruler over your open eye, centered on your pupil.
Without moving the ruler, open your closed eye and place your finger over the ruler in line with your pupil. Read the millimeter measurement under your finger to get an estimate for your IPD.
Adjusting Quest 2 IPD
To change the lens spacing on your Oculus Quest 2, gently adjust the lenses by shifting them together or apart. There are three lens spacing settings for Quest 2.
If you know your IPD, the table below shows which lens spacing setting we suggest.
|IPD Range||Lens Spacing Setting|
|61 mm or smaller|| 1 (narrowest, 58 mm)|
|61 mm to 66 mm||2 (middle, 63mm)|
| 66mm or larger|| 3 (widest, 68mm)|
Keep in mind that these are only suggestions, particularly if your IPD is on or near the edge of each lens spacing setting’s suggested range. The best setting for you can depend on numerous factors, including things that can change with each use, like where a piece of content has you directing your gaze or how the headset is positioned on your face when you put it on. Don't hesitate to try a different lens spacing setting to see if it improves image clarity for you.
Adjusting Quest IPD
To change the IPD on your Oculus Quest, gently move the slider on the bottom left side of the headset from the left to the right.
