Does your hand not work or something? Close your damn fist. You're in a fist fight. Why are you extending your fingers out when that's already illegal and not useful for your fight?
If you have to rely on a glove forcing your hand closed you're the problem, not the glove. You're trying to fix your bad tendencies and breaking of the existing rules by taking it out of your control instead of just not doing it.
I'm not saying things COULDN'T be better, but the issue is always ultimately the fighters. Better designed gloves will still cause eyepokes if fighters are just poorly controlling their hands. Which is the real issue.
