We're still probably millennia away from developing night vision. In the meantime, we'll just to have to make up for this human evolutionary flaw with glow-in-the-dark spray paint ($10). Apply the paint to most surfaces (plastic, wood, metal, etc.) and watch it give off a greenish glow once the sun goes down. Spray your light switch cover and you'll never have to grope the walls looking for the light in the middle of the night again.
