Knowing exactly who and who does not wear glasses in a novel is a bit of a guessing game.  A character might be wearing glasses, but the narrator might decide not to tell readers that detail.  I always assume characters in books are wearing shoes and pants, but texts very rarely include that detail.  

With that said, I know the following three characters all wear glasses in A Wrinkle in Time.  Meg Murry wears glasses, and they are a major part of her identity throughout the novel.  Her father, Mr. Murry, wears glasses.  Finally, Mrs. Who wears glasses, and she will eventually give her glasses to Meg.  Chapter nine has an interesting little sequence in it regarding those characters and glasses, because at one point both Meg Murry and Mr. Murry end up wearing Mrs. Who's glasses.  It had to have looked quite comical, because the reader is told early on that Mrs. Who's glasses are big.

The enormous glasses caught the light again and shone like an owl's eyes.
