I remember reading a oneshot, either as part of a collection or an extra story in another manga.

All I remember is that the two guys were old friends and one started to notice the other only when he would wear his glasses.I think the one who wore glasses had long hair.

I know that's not much to go on, but if anyone remembers please please please let me know.

THANKS!

I have no idea, but you can always go through the categories:
Long Haired Male
Yaoi+Glasses

🙂
And to filter the other genres

Tsutaete ii no ?

I just read this, like, yesterday, believe it or not. Sounds like Story 6 in Trigger, "The Power of Glasses." All the stories in this collection are good.
