Magic Leap CEO Rony Abovitz states that Microsoft’s HoloLens is causing possible brain damage: “There are a class of devices (see-through and non-see-through) called stereoscopic 3D. We at Magic Leap believe these inputs into the eye-brain system are incorrect — and can cause a spectrum of temporary and/or permanent neurologic deficits”. He adds: “our philosophy as a company (and my personal view) is to “leave no footprints” in the brain. The brain is very neuroplastic – and there is no doubt that near-eye stereoscopic 3D systems have the potential to cause neurologic change. There is a history (for optics geeks) of issues that near-eye stereoscopic 3D may cause — but this has always been very limited use and small populations (like the military). We have done an internal hazard and risk analysis (like the kind I did from my med-tech/surgical robotics days) on the spectrum of hazards that may occur to a wide array of users. Frequency of use, duration of use, and the neuroplasticity of the user are all key factors – but because we are all people – we may all be impacted.”
Nick Statt looks for the reality value of Abovitz statements. He comes up with Joyce Farrell: “Farrell, the executive director of the Stanford Center for Image Systems Engineering, said Abovitz’s claims hold little water beyond a light-field display — as Magic Leap claims to have — being easier on the eyes. “The thing that people are complaining about that may cause fatigue is that you have to converge your eyes at a certain place in a certain way that is non consistent with natural viewing,” she told CNET of stereoscopic displays like the Oculus Rift.”
