The problem is not lack of intellegence, but that a laser beam is invisible until it strikes something. So if it hits a reflective surface it can reflect back into the eye and instantly blind you on one area of the retnia. The glasses are highly recommended if working with a laser over 2 mw. The reflection can happen very suddenly and unexpectedly, IE if you are positioning it and it hits anything reflective, or if someone walks through the laser beam, and has something reflective on them, a belt buckle, a pen or anything.
