I haven't read any manga with blind characters that aren't action-based, so maybe have a look-see here:

Oh wait it's Can't See, Can't Hear, But Love
Adding to t8nt3d's suggestion of Koe no Katachi, there's a movie of it called "A silent voice"
Awww already read those two but will try looking for more!
I love that one! Gave me so much feels
Gonna add this to my reading list. Thank you so much!
Pls recommend me some manga with deaf and/or blind characters where the main focus is their ability, how they cope, and has so many inner monologue
