A system for preventing damage to the eyes of a person being within a certain distance from a high-power laser, including a device for ascertaining the absence of a person within this range, and a device for actuating the high power laser only if the results indicate that no such person is present in the specified range. There is also provided a method for eye protection against damage by high-output lasers, which comprises examining such a range with a low power laser or other similar device, harmless to a person's eyes within the specific range, and for actuating high power laser radiation only after a clear indication that no person is present within the dangerous range.
