EN 166 F & B

[Sako]

So having decided I need to wear prescription safety glasses, I’ve decided that the Bolle tracker II fits the bill, the exception being the impact rating on the lens. The impact rating for a 166 F seems insufficient for Airsoft. Which leaves the next to be 166 B (a little more elusive).

i have found these but am unable to decipher whether they are stipulating the lens to be 166B. Anyone able to confirm or clarify based on experience?
