night vision

night vision goggles
won't let you see into a soul
but they will help you spy on someone
or make a kill once the sun has set.
they are made to be light
fit your head comfortably
and enhance an image
so the advantage is yours, in theory.
green is the color humans see best
and it's not envy
so if you're hiking
after dark
on a moonless trail,
are worried about the footing,
wear a pair.
