Paul and Andrew at Lucky Gunner labs did some serious testing on various forms of eye protection. Nothing more complicated than a price range of eye pro (or improvised eye pro), styrofoam heads, and two guns.
If you value your vision, these tests are worth your time.
It really has me rethinking my eye protection.
Paul emailed me with the link to their testing, and I found it of significant value, which is why I posted it.
