On the whole CE marking eye protection do people realise that the highest rating for specs is F? If you want to achieve B they must be Goggles which fully encase your eye from outside impact?
I see a lot of people saying what is good and no good but without full understanding of the standard they are tested to.
Edit: has been a few years (2013) since I checked this mind and I am happy to be corrected if wrong.
Specs can only achieve F in the CE marking scheme for industrial eyewear, however there ARE ballistic rated glasses that have a far higher impact resistance (Bolle Tactical have some for starters).
