Based on recent research on the subject ( I bought and paid for all the referenced standards documents), I've changed my assessment. I won't be using ANSI z87.1 or ASTM F1776 goggles personally anymore. My eyewear will have to be mil-dtl-43511d with full closure like pb goggles. The ANSI Z87.1+ allows for eyewear with gaps and is only tested for industrial applications. ASTM F1776 has testing only for paintballs. Neither test protocols comes close to the analog of intentional high velocity BB rounds and intentional targeting the way the mil standard covers. In essence the mil standard goes all the way to 1.1g at 550 fps - using metal projectiles. This standard far exceeds all materials, speeds and impact velocities of airsoft as we play it.
I'm going to post more information on the Bastard site once I have had a chance to formally and in a detailed manner, dissect the other standards and document my argument with references.
I think playing with anything below that standard is exposing yourself to undo risk of eye damage.
