Because Japan is obsessed with adorable things and he went crazy over Italy's eyes, so Italy keeps them shut.
There isn't really a reason, but I found this: Italy in Axis Powers Hetalia is usually drawn with eyes that resemble equals signs. Aside from some of the official art advertising the manga/anime, he only opens his eyes TWICE in the course of eighty-some episodes. They even make fun of it in one strip, in which he wakes up, opens his eyes, and gasps. A caption underneath states "'I tried opening my eyes today!' - Italy". Made even better during Bloodbath 2011, when one of the requests was that he keep his eyes open. After about ten seconds, all the other characters were freaked out, and Germany ended up covering Italy's face.
3rd Answereer says: "It wouldn't be safe, it wouldn't be prudent..."
* 4: "Either Italy has uneven vision (squinting) or he is photosensitive."
- or he is hiding his real expression through his eyes.
