I agree with just about every post in this thread. It boils down to the fact that if your life is not in danger in a street fight, by which I mean it is just you and another guy banging it out then you don’t really need to eye gouge him.
But then you also have to remember that there are no rules in a street fight at all, everything goes everything. I used to be a LEO in the Military and in Civilian life so I know what trouble you can bring upon yourself.
But the streets are know joking matter and everything in the world goes in a street fight, so if you must then do so. But I recommend that if you beating the hell out of the guy that you don’t but if your taking a beating and need to do so and have the shot then go for it.
Just use your head, most of the time it is better to walk away.
