 So eye rolling, I think we can agree, is considered a toxic behavior. It's dismissive. But science says we cannot help rolling our eyes. It's a hard-to-control reflex that's literally your brain's way of trying to get as far away from something as possible. This is according to body language expert Dr. Lillian Glass. She says neurologically, when we find something offensive or ridiculous or something that doesn't make sense, the brain signals to your eyes to roll as a way of disconnecting.
