Not correct, sorry. Under the Australian Standard Sun glasses are only required to provide about half the impact resistance of standard safety glasses. Often not polycarbonate. No matter the cost. Prescription glasses are the same. The US standard has a slightly higher level of impact resistance. They are often sold as shooting glasses here. But the additional cost is difficult to justify as the improvement is small. You can buy a reasonable pair of safety glasses for $15. And yes safety glasses are always polycarbonate, usually about 1.2mm thick. 1 mm of polycarbonate provides 99% UV protection.
By the way this area is an honesty system and hardly policed. So often imports are not made to the standard. But safety shops are normally careful to only sell glasses to the standard.
Edit note: I doubt if most of the range officers would know the difference or how to check.
