Okay, so what I'm hearing is that not only are eye jabs/gouges evil, they're also less effective than punches, kicks, and grappling moves? I'm gonna call bulls*** on this one...
No, attacks to vital targets (eyes, throat, knees, groin, etc.) should not be used in "fights." However, as others have said, you shouldn't be getting into fights (mutual combat between idiots with ego problems). Unless you work in a profession that makes physical confrontations more common (LEO, bouncer, security, etc.) if you get into a lot of fights you need to examine your behavior/conduct and figure out what needs to change so that you don't get into a lot of fights.
Now, back to the issue of self-defense. If you are targeted as the victim of a violent crime (rape, robbery, kidnapping, etc.) you do whatever it takes to make sure that you're the one that walks away. It doesn't matter if that "whatever" includes gouging their eyes, using a weapon, or tearing their throat out with your teeth if need be.
