   But you don't have to get *that* powerful before the blink reflex won't   
   save your sight any more. I've got some 2.5W violet lasers here that will   
   blind someone *instantly* and cause permanent scarring on the retina.   
   Mind you, these are about 500x more powerful than the average laser   
   pointer.
