Adjusting the IPD on the headset
Interpupillary distance (IPD) is the distance between the centers of your eyes.
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.
To increase the distance between the lenses, rotate the IPD knob clockwise. To decrease, rotate the IPD knob counterclockwise.
As you adjust the IPD, you'll see a prompt indicating the current distance between the centers of the lenses.
Why is accurate IPD important?
Accurate IPD settings help get a clear image and reduce eye strain.
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?
There are several ways to estimate your IPD.
The most accurate way to determine your IPD is to consult a professional optometrist or eye doctor. You can also estimate your IPD by doing any of the following:
- Use a ruler and a mirror. See below for detailed instructions.
- Through experimentation. See below for detailed instructions.
- Using third-party apps or websites.
Note: Third-party apps or websites may collect personal data. HTC cannot guarantee accuracy of third-party apps or websites in measuring IPD.
Estimating your IPD in a mirror
You can estimate your IPD with a ruler and mirror.
This method requires a millimeter ruler.
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.
Tip: You can also ask a friend to help you measure instead of using a mirror. Make sure you're looking straight ahead while they measure.
Estimating your IPD through experimentation
You can estimate IPD by trying different settings. This method is very convenient, but might be less accurate.
- 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 knob 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.
