HealthLens are holographic glasses. On the drive to the hospital, Emergency Medical Technicians (EMTs) and paramedics use these glasses to save more patients. The HealthLens scan, project, and announce the patients' health status and their symptoms' locations. The Lens then link the patients' symptoms to possible health conditions; EMTs aid these symptoms. Scientists today can integrate existing holographic lasers into glasses and program them with medical information to create HoloLens.
