My question was more directed towards where I could buy the raw material (unclear wording, my bad). I did find a sheet of polymer doped acrylic (OD3), I will cut it to match my glasses lenses and glue them to a flip-up frame clip. If you can't find any casual-looking eye protection, just make...

What materials are laser goggles made of? I would like to make a custom pair to clip on my glasses. Due to the environment in which I will be using the lasers, I only need to protect myself from the diffusion, not the beam itself.

I don't understand why it's so hard to make parallel beams for laser pointers. If you can refract light any way you want, couldn't you adapt a lens' surface according to its input to point every incoming photon straight out?
