This is the first scary question that everyone asks with these devices, because the answer is "you burn a hole in your retina". It is an inherent danger in the system, but I would be interested in reading a full risk analysis on this type of system. Industrial processes always have risk analysis and avoidance, with failsafe for all possible failure modes being desired. I wonder what kind of hardware failsafes you could put into this. You never, under any circumstances, want to burn someone's eye. But you also don't want someone's expensive toy to brick itself because they jumped with it on.
