The Vision Laboratory located at Naval Air Systems Command (NAVAIR) onboard Naval Air Station (NAS) Patuxent River, Maryland (MD), developed the Laser Event Recorder (LER), a device that instantly warns aviators about laser radiation potentially hazardous to their eyesight. The LER gives simple feedback to the aircrew at the time of a laser event, and records detailed information onto a compact flash card for later analysis by intelligence officers, medical staff and aircrews. Sensors currently in use can't cover the complete range of laser threats, nor can they let aviators know whether or not a laser pointed in their direction is dangerous to eyesight
