Infrared Goggles
Guy Macon
While doing a web search on color filters for astronomy
flashlights, I came across this:
http://amasci.com/amateur/irgoggl.html
What he is doing is to block out all of the visible light and
to allow the near IR from a bright sunny day to hit his dark
adapted eyes. He describes the result:
"After I became accustomed to the darkness inside the
filters, I could see through them. Going outside on
a sunny day was stunning. The sky was almost black,
while the trees and shrubs where all frosty pink.
The grass looked like fluorescent red cherry Koolaid
powder. Different colors of human skin were always
the same light grey. People's eyes looked very black,
and certain dark clothing looked white.
If nothing else, these might be able to let me adapt my eyes
for night-time astronomy while allowing me to see well enough
during the day to set up my gear.

My wife bought me a set of red goggles from the Orion catalog, I
think, for that purpose. They are just like the soft plastic eye
protection I use for carpentry except they are all red with a red
lens. I don't normally use them during the day when the sun is out,
but at twilight when setting up or after dark when I have to run back
inside the house to pick up something. I can see perfectly well but
everything is red. The eyes start adjusting to the lower light
immediately and stay that way.
There are at least two versions out there. A British (?) company
called Astro Engineering makes a pair called Nite-Saver red goggles:

The one I have is called the Orion red tinted astrogoggle and can be
found in the Orion catalog:

The only thing about them is you look real dorky to other people, but
I've got that problem whether I'm wearing them or not. ;)

Those sound like a really good idea. I often go out to death valley
to do astonomy, and it gets really bright uring the day.
Something like astronomy goggles is an ideal product for someone
who is just stating up a new company; low volume, low production
costs, and a couple of magazines that many of the potential
customers read.
