There is a difference between an eye gouge and a simple touch/thrust. You can go at the eyes FAST but with control, kinda like a serious version of the "Three stooges" eye poke. It's more about being a painful, but not debilitating, distraction that results in what @gpseymour notes, but also as he notes, because it is not an all out strike, once you are prepared for it and know how to deal with it, it's not overly difficult to deal with BUT that is the point, imo, of my "cross training" number 2.
In that case the WC guy will learn that "yeah this sudden but little damaging tactic will work against the unprepared". The BJJ guy overtime learns to be prepared. The WC guy then learns not to be overly reliant on it. Everyone learns something!
PS, unless you are practicing Iron palm training doing a thrust that is more than a "touch" will get your fingers jammed or broken fairly easily if the opponent tucks his jaw right and you hit his forehead. I know two people that practice Iron palm enough that they can slam their finger tips into their own foreheads repeatedly and you can hear the impact across the training room floor. I don't even want to think of what they could do thrusting on any soft portion of the body tbh.
Well then go roll with whatever variation of eye gouge or eye jabs you want. It is not the point. If you want to roll that way go buck wild.
