Considering so many people (including me) tend to use safety glasses as forehead protectors than eye protectors and have to be told repeatedly to wear them properly maybe they figure if you wear them properly not only will the protect your eyes from injury but you won't get screamed at by the safety people and the mentors (particularly the ones running shop) and thus your ears won't be bleeding from the bawling out you'd get from them.
