Googled again with the info you gave me and I got this.
NOTE: This is from a company website who manufactures safety products.
The lenses are high impact rated and offer 99.9% protection against UVA-UVB up to 385 nm. All are SEI certified to ANSI Z87.1-2003 and the LS4 also meets CSAZ94.3-2007.
(NOTE: Some sections bolded for effect.)
That section I quoted above after reading the wording a few times it appears that the CSA rating is approximately equivalent if not offering slightly higher protection standards.
I'm going to test these out at the field before I use them though. What do you guys suggest? I'm thinking 3-5 feet away with a .25 going somewhere between 330-340 FPS.
