A Class 3A laser is low powered. It normally would not harm eyes during a momentary exposure of less than ¼ second. This is within the aversion response, where a person turns away and/or blinks to avoid bright light. Do not deliberately look or stare into the laser beam. Laser protective eyewear is normally not necessary. A class 3a laser pointer is not a skin or materials burn hazard. However, a class iiia laser can be a distraction, glare or flashblindness hazard for pilots and drivers. NEVER aim any laser towards an aircraft or vehicle that is in motion.
