I have read some mangas where the main girl goes blind or deaf or whatever and I was wondering if there were any where it was the guy instead. Thanks.

you can try Can't See Can't Hear But Love, if you don't mind manhwa.

dont know what else you are looking for except main guy blind/deaf...
Teiden Shoujo to Hanemushi no Orchestra - action manga with blind protagonist
Shi ga Futari o Wakatsu Made - action as well

[Edit]
ah sorry didnt read carefully, you’re looking for manga where mc goes blind during the story(?); in my suggestions both mc are alreasdy blind

Thank you for the suggestions. I'm not really picky. 🙂 I just read a oneshot about the girl going blind and I wondered if there was a story that it was the guy instead. 🙂

Kingyo Sou - really sweet romance where the main guy is deaf.
