Adjusting The Ipd On The Headset - HTC VIVE FOCUS 3 User Manual

18 Getting started

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
guide to adjust the distance between the lenses of the headset so that you'll have a better viewing
experience.
To decrease the distance between the lenses, rotate the IPD dial clockwise. To increase, rotate
the IPD dial 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.
