Adjusting the IPD on the headset
If you don't know your IPD, see How can I find my IPD?. Use this measurement as a guide to adjust the distance between the lenses of the headset so that you'll have a better viewing experience.
Why is accurate IPD important?
The headset lenses focus images toward their optical center. This is sometimes called the "sweet spot" in the VR industry. By adjusting the IPD knob, you can tune the sweet spot for the most comfortable view. Misaligned IPD and improperly adjusted headsets are common causes of blurry images, dizziness, and eye strain.
How can I find my IPD?
- Use a ruler and a mirror. See below for detailed instructions.
- Through experimentation. See below for detailed instructions.
- Using third-party apps or websites.
Estimating your IPD in a mirror
Stand directly in front of a mirror, and then hold the ruler up to your eyes.
Make sure that the ruler is level. If you're using a flexible ruler, make sure not to bend it.
Align the zero mark with the center of your pupil.
You may need to close your other eye to get a clear measure.
Check the millimeter mark on the other eye. You may need to close the first eye to get a clear measure.
- Make a note of your IPD measurement. You may want to recheck several times to make sure your reading is accurate.
Estimating your IPD through experimentation
- While wearing the VR headset, focus on text or lines at the center of view. If no text is present, open a screen in VR with text.
- Adjust the IPD dial until the text is clear. Note the number for future use.
- If the image in one eye is clearer than the other, adjust the headset position. Repeat until images are clear for both eyes.
