As Flatlander posted, there are 2 ANSI z87.1 levels: Basic and High Impact (+).

AFAIK, all companies label Basic (and maybe the occasional High Impact) as safety/shooting glasses, and only use the term "ballistic" if they exceed the High Impact. For obvious liability reasons.

I don't think ANSI really deals with surface damage around the impact area, if no failure that threatens the wearer occurred. Slight surface deformation is acceptable, since the lens did in fact protect the eye fully. ANSI isn't a standard for whether the lens can shrug off a hit without losing optical quality, since the expectation is that the glasses will be replaced after such a trauma (like in paintball, theoretically).
