A system for preventing damage to the eyes of a person being within a certain distance from a high-power laser (11), comprising means (18, 19, 21, 22) to ascertain the absence of a person within this range, and means (13) 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 (19) or other means, harmless to person 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. <IMAGE>
