I will insert here, Greg, that I am a life-long solid proponent of "Close your eyes, turn off the light, count to ten; then open your eyes."
You will see a lot more without the light (assuming you're nor spelunking, of course). I amazed 28 years worth of Boy Scouts with that. Try it, you'll like it.
