Finding fanfics where Naruto is blind from the start is tricky because a lot of them just use it as a quick angst setup before a healing jutsu fixes everything by chapter three. I get annoyed when the disability is treated like a temporary obstacle instead of a core part of his character. The ones that actually explore overcoming adversity are usually slower, more grounded stories where he has to develop entirely different skills.
There's this one I read years ago, I can't remember the title, but he never gains any kind of supernatural sight. He becomes terrifyingly good at wind release and sound-based sensing, but the story was more about the village's prejudice against a 'broken' jinchuriki. The real adversity wasn't the blindness itself, but how Konoha's system failed to accommodate him. It abandoned the standard shonen power climb for a more political struggle, which I found way more compelling. Sadly it seems to be dead now, last updated in 2017.
Those stories often hinge on his relationship with Iruka or a reluctantly impressed Kakashi becoming his true teachers, adapting training methods. The fight scenes, when they happen, are written with a focus on tactical thinking over flashy visuals.
