I'm sure the inverse square law applies, but I wonder if these highly 
directional beams are still dangerous at greater distances than we're 
accustomed to. Taking directionality to an extreme, lasers are dangerous, or at 
least very annoying, from a great distance.

Let's assume we're still talking about human eyes.
