I gave it six months before going back -- 15 years ago. My sister tried them at the same time and is still happily using contacts.

My midget quickly learned that grabbing glasses did not elicit any more reaction than someone dispassionately removing them from her hands, so it was a short phase for her.

Now she has so many pairs of sunglasses that I sewed a simple loopy elastic holder to hang them all up on her bathroom wall. (I originally planned to make the holder for her cache of lip balm, but then I imagined capless lip balms leaving marks all over the wall.)
