I don't know if it matters to you, but if I remember correctly the 580p lenses are z87 rated but the frames are not.
No Costa products are z87 rated. For them to meet the z87 standards they must be stamped with z87 and no Costas have that. Really only an important distinction in the world of workplace safety. The Costa lenses made from polycarbonate come with a certificate say they meet or exceed z87 standards. Now if they do in fact meet z87 standards I don't know why they wouldn't stamp the lenses and frames.
Yep. If you want certified safety glasses like that, look at Wiley X.
As for lens color, green cuts down on more sunlight, but copper / amber / etc. has been slightly better for contrast and seeing into the water. But I still find myself squinting sometimes.
