The test results below in the video are more or less what I expected. But I thought 5 meters was a bit harsh. And not exactly a laboratory test. But just goes to show.
All safety glasses sold in OZ need to comply with the relevent Australian STD. In the US the equivalent is the ANSI Stds. They do vary slightly, as is often the case but for safety glasses are very similar.

I don't think you can go far wrong with a $15 pair of safety glasses from the local safety shop. But some are better optically.
