Not only does Miyuki wear glasses, she's also incredibly smart, and most importantly very nice. It's actually kind of surprising how few "nice and smart people" there are in anime who have a main character role, rather than side character; the primary one which comes to mind offhand is Belldandy from Ah My Goddess, but her Divine Intellect is not exactly portrayed often in either anime or manga. (In fact, she's kind of spacey in the earlier manga chapters, played up for comedy.) Also, Yomiko Readman from Read Or Die, one of the sexiest characters I've ever seen.

I'm under the impression that after a while, a particularly high intelligence in Real Life tends to result more in cynicism, rather than optimism. On the "nicer" end of the scale, we get the Deadpan Snarker, like (famously) Kyon from Melancholy of Haruhi Suzumiya. As we progress towards less empathy and more RAGE, we end up with the "I hate people because everyone except me is stupid" types, which I've always had problems talking to. My worldview is that everyone should be nice to each other, and they believe that they have an inalienable right to be a complete… well, I'll just leave it at that to prevent myself from descending into a full-blown rant.

I wonder what sort of character archetypes Miyuki would be classified under in the Great Fandom Classification. (Yes, I'm aware that many times, these pigeon-holes are not precisely accurate, or even appropriate.) There's the obvious meganekko, and as Konata points out, she also has elements of dojikko, a trait which I've never seen portrayed as "cute" except in anime, although once again absence of evidence is not evidence of absence. I don't know if there's a fandom term for "smart girl", "nice girl", or "smart and nice girl". I wonder if "smart and nice", male or female, really are that rare, in anime or in Real Life.

Yes, I went there.
