Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The offset read-only property of the VREyeParameters interface represents the offset from the center point between the user's eyes to the center of the eye, measured in meters.
Note: This property was part of the old WebVR API. It has been superseded by the WebXR Device API.
This value should represent half the user's interpupillary distance (IPD), but may also represent the distance from the center point of the headset to the center point of the lens for the given eye.
