Heph's Magical Adjustable (burningman) Goggles of DOOM.

Burning Man goggles are a bitch, you need a dark pair for the dust storms and the sun in the day and a clear pair for the dust storms that happen at night. Using camera lens circular polarizers I was able to make an adjustable-tint pair of goggles I can wear day or night.

I started with some standard army-surplus-store goggles, removed the lenses, measured the inner diameter with a pair of digital calipers, and got on amazon. The smallest ID of the goggles was 44mm. I found an incredible deal on some 46mm CPLs on amazon, and since the goggles are a soft plastic, they accepted the slight size-mismatch fine.

I removed the existing lenses, put one polarizer in place over each eye, used electrical tape to hold them in place, and to mask the JB-Weld from going anywhere I didn't want it. I mixed the JB-Weld and put it in a hobby syringe to squirt it into the tiny gaps between the filter and the goggles frame. This resulted in a pretty smooth joint that's very solid.

I cut down the prescription lenses from an old pair of glasses and hot-glued them in place inside the goggles, a trick I've done for several previous sets since I don't wear contact-lenses.

Then I just added the other polarizers to the top, and now, just by rotating the outer polarizer in relation to the inner, I have adjustable-tint burningman goggles of doom.
