I have, with nothing but an open faced helmet (face visor flipped up or removed) and normal eyeglasses, which have a quarter inch or more space between my face and the lens.
Speaking of visor, why aren’t there any dog helmets with visors? Assuming the dog did not find it too annoying, it would look cool and help with the eyes, and the dog could safely do what it finds fun.
“and normal eyeglasses”
You had eye protection, albeit poor eye protection.
Can you imagine the time and expense of creating helmet and visors properly formed for all the myriad breeds?
It’s just not feasible.
