How to get Oculus physical lens spacing in Unity

Hi, Oculus rift has a “Change lens spacing” screen where you can adjust the slider of lens spacing and the value would show changing.
In Unity is it possible to get this value?
Thanks.

Correct answer by Oculus staff
Vector3.Distance(UnityEngine.VR.InputTracking.GetLocalPosition(UnityEngine.VR.VRNode.LeftEye), UnityEngine.VR.InputTracking.GetLocalPosition(UnityEngine.VR.VRNode.RightEye));
