Magic Leap One Sicherheitshinweise Seite 5

titled "Warning: Unsuccessful Visual Calibration." For an optimal
experience, we recommend Magic Leap One be used by people with
an interpupillary distance ("IPD") that is between 54 - 76 millimeters.
If you have an IPD outside that range, you may have a greater chance
of experiencing visual pain or discomfort and you may not have full
visibility of your display. Please review the section below titled "Small
Versus Large Size Device" for more information.
When you first use Magic Leap One, start with the volume at
a low level and then increase the volume until you hear the sound
clearly and comfortably. Use caution to avoid turning up the volume
too high. To prevent possible hearing damage, do not listen at high
volume levels for long periods.
See a doctor before using Magic Leap One if you: have any
conditions that impair your vision (e.g. binocular vision disorder) or
mobility; are pregnant or elderly; or have a heart condition or serious
medical condition; seizures; or migraines.
Unsuccessful Visual Calibration May Result
in Visual Discomfort
You might have a greater chance of experiencing visual discomfort if
you do not successfully complete Visual Calibration. Magic Leap One
relies on eye tracking to render content in a way that is designed to
be comfortable for your eyes. Upon completing the Visual Calibration
process, your device will let you know if you successfully completed it.
