Update: I thought I would post the actual maker of these goggles, too. The website is: http://www.smugmug.com/gallery/6278166_YCdn5. There are a lot more photos and details at this site.
It’s entirely possible that Mike Brown overdosed on ADD meds: These brass goggles scream “attention to detail.
Some numbers: The leather is actually bolted to the eyepieces, using 48 tiny bolts plus another four for the nosepiece. The leather was chosen for the tanning process which should give it a klife of a few thousand years.
Ditto the eyepieces, which are machines from titanium and coated with Titanium Nitride. Predicted lifespan: 500 years plus. There are even brass eyelets in the leather eyecups to stop the lenses steaming up.
Mike put in a few nice extras, too. The sliders in each eyepiece close the leaf-apertures inside, which will cut out light and also sharpen your eyesight, just like a pinhole camera. The lenses themselves react to light and get darker the brighter it is.
