Meaning of 瞳だけはぶっ飛ばない


Context: in a gym, a boxer attacks another boxer saying that he was provoking
him with his eyes. After punching him, he thinks:

> **瞳だけはぶっ飛ばねー** でやんの  
>  甘ちゃんのクセに
>
> 人殴って拳が潤わなかったなんて  
>  ねーのに……

What is the meaning of the verb ぶっ飛ぶ when it refers to the eyes? Looking at
its meanings in the dictionary I couldn't find one that fits the context. Is
it used metaphorically here?

Also, could you please explain the grammar behind ぶっ飛ばねーでやんの? Is it the
contracted form of ぶっ飛ばないでやるの?

Thank you for your help!

**EDIT:** since it looks like a strange metaphor, I uploaded the original
pages to provide more context.

used with め furigana)

I think 瞳だけはぶっ飛ばねー has the similar meanig of 目だけは死んでない, which means "He still
has a fighting sprit (even if his body was damaged)." and "He hasn't yielded
yet (even if his body was damaged)." It isn't a common phrase.

As for the grammar, I found an explanation, and it says 「～でやがるの」changed to
「～でやんの」. やがる is used when you say about someone's action with contempt or
hatred such as 学校来ねーでやがる. About の, a dictionary says 断定の言い方を和らげる意を表す.




Tbh the sentence doesn't make a lot of sense - it reads like somebody tried to
incorporate many advanced vocabularies without really understanding how they
are used. There are also a few grammatical mistakes.

Having said that, if I'm forced my guess would be that the opponent kept his
gaze on the attacker, despite (other parts of the body) being punched away.

It's very hard to tell though, as 瞳 is overwhelmingly used for adorable
things. An exception is when it's used to describe the pupil specifically, so
it's possible but it's not obvious to me why the writer would focus on the
pupil. It's also a physically odd situation (body moving away but the pupil
remains?). ぶっ飛ぶ can also refer to blackouts, but then it's also odd (one is
unconscious, but the pupil remains conscious?).

I think you'll have to ask the writer - maybe they knew what they wanted to
express, but they are probably not yet proficient enough in Japanese to
express it.

**EDIT:** After looking at the context, I suppose the writer is going for a
VERY creative, unorthodox writing. They probably added the "め" in ふりがな because
hitomi wouldn't fit (it will make things sound very adorable), but they still
wanted to focus on the pupil. They also say "拳が潤う" which is extremely odd （潤う
only refers to pleasant moisture), but it makes sense because the character
then talks about erection... "潤わなかったなんてねーのに" is probably a misprint of
"潤わなかったことなんてねーのに". I think you have to interpret it with your own creativity.
It's not a common expression by any means and I guess you are meant to
interpret it in your own way.
