Okay.
I bought my goggles on Ebay from a guy out of Florida who runs a shop called pro-steampunk. He has an ebay store, a website, and a few other things... I'll post links here.

http://www.pro-steampunk.com/His goggles are a bit on the pricey side but he hand paints and details every one of them, so I understand the price. When I ordered one off of him, I picked the ones I liked the best and asked him if he would be willing to add details from other goggles he had on sale. He said he didn't normally do custom jobs, which is odd because his store says "hand made to order" which implies he custom makes them to order. But whatever. He originally quoted a higher price for the custom order, but then took a decent amount off of the final price. A pretty pleasant guy to work with, although I'll say he's a little slow to respond and talks in an odd way over email.
So, now for pictures of the goggles. The brown thing is my deerskin leather gloves, which was keeping them from tipping over.

A closeup of the gears:



Just recently I created a little LED thing to make the magnifier glow. It's an LED soldered to a cr2032 holder. The tape on the end is just masking tape, it diffuses a rather bright LED beam. This fits to the goggle lens.

The goggles are a bit heavy, so need a good hat to put them on. Also, notice the clamps on the goggles. Originally, the goggles came with radiator hose clamps, which are common with online steampunk goggles but I absolutely think are very un-steampunk. So, I found these very nice clamps on Ebay, from a seller in Arizona. I don't know if he sells internationally. But the clamps are lighter and a vast improvement.
Here's his store:

So I can modify them in many different configurations, with the giant magnifier, without it, with the gear lens or without, or clear so I can see through them.
Some things I'd like to do to these in the future include adding a leather strap instead of the non-period spandex strap. I'd like to put padding around the edges of the goggles, similar to aviator goggle padding. And I'd like to do something with that LED attached to the outside of the magnifier funnel, it looks a bit out of place. I would like to replace it with something. Any suggestions on any of these, like leather straps, or padding, would be great!
