So I have plans to make some more goggles, and I would like to add those flip down lenses on a rod that I see on a lot of other goggles.  However, I have no idea how to start.  What sort of rod do I use so that they have the right amount of friction, and where do I find/how do I make the lenses themselves?
If anyone is unsure what kind I'm talking about, it's the ones that look like this:

Thanks!

I just bought a clip on set of those lense thingies at a convention.

I don't think I can post a picture directly, so let me describe it to you.

each lense is on a long arm (the arms on mine are hexagonal). 
the arm enters a small clamping block with screw, so you can adjust the lense distance from the block
the block has a second hole that a long screw is slid into.
I have 3 lenses on mine, so that's 3 block/arms stacked onto this screw
after the 3 blocks, is a spring, supplying tension to the blocks (so they don't flail about)
then the squeezy clip (for clipping to glasses frame on the side)
then the nut for capping this all off.

So in bad ASCII art, here it is:

I'll see if I can snap a pic, put it on a photo hosting site and link it proper.  It's a simple device really.

A picture's worth a thousand words and a bit of googlefu revealed it.

Apologies for posting to a vendor, but it's the first hit I got and I don't think I should nab the image from their site.

https://www.amazon.com/Hawk-MG922D-Clip-Double-Loupe/dp/B000YMZJX2

This is basically just like what I bought, same knurling on the ends of the screw pole.

then end where the clip is is the threaded part, so you could unscrew it, swap out the clip for something that connects to your goggles and put the end nut back on.

That was my basic plan to mount them to my goggles.  I felt the closest lense was scratchingly close to my actual glasses lense when I tried clipping them on.  Might need a longer screw pole.

Search ebay for "clip on jewellers loupe" if you want coloured ones I would suggest a second search for "glass paint"

Alright, thanks!  I'll probably just end up buying one then; they seem reasonably priced.

Alternatively, have a look at camera lens filters - These come in quite a wide range of sizes and colours, but the glass ones can be quite thick (typically, 2-3mm). If you want thin, then I'd suggest some lighting gels which are around 0.25mm thick.

See if you can blag a swatch book from a Lee Filters supplier (or have a look at http://www.leefilters.com/lighting/lighting-resources.html )
