You are lucky you didn't lose your eye. (I'm not saying you are responsible, it's just that most eye-shot stories I hear involve losing an eye).
I hope your injury heals on it's own. Luckily, if only your lens is injured (I am pretty sure) at the very worst you would need a lens transplant to restore sight to the eye.
