Abstract The classification of the safety of lasers according to classes 2, 2M and 3A is mainly based on the aversion responses including the blink reflex. However, this study carried out on 1200 volunteers shows that the blink reflex occurs in a maximum of 20% of all cases if an irradiation is performed under class-2 conditions. Further active protection reactions in form of head movements and eye closure occur in less than 10% of subjects. A second trial with 200 volunteers who received prior training showed that active protection reactions could protect up to 80% of the exposed volunteers against laser radiation within a period of two seconds. Implications of these findings are discussed.
