I am pretty sure they asked how she was feeling and she said she was fine. I think for the most part people took her word for it. They noticed the white eyes but I suspect since it appeared she could see fine, or perhaps better since she seemed to have a heightened sensitivity to Aether, it was taken as a cosmetic change. I certainly assumed it was just a cosmetic change until Matoya mentioned it.

As I said before, we knew already what happened to her. We could have said 'your eyes are white, are you sure you feel ok?' to which she probably would have responded 'I'm fine'. Let's remember Y'shtola actively hid her blindness from the rest. Thancred is pretty much the same. He has kept the limitations he now suffers from his allies as well.
