You can convey the general ethos of the world with broad descriptions and leave the rest of the details to the reader's imagination. Also, one may decide to spend more detail on eyes than on other aspects of a character's image depending on which features of the character are more important for highlighting their persona, even though a "huge block of text" is hardly conceivable. The character also doesn't have to be described exhaustively upfront, as has already been noted. Character introduction can occur subtly over time and through events as has already been stated.
