As if you don't know where the camera is. People with normal vision will typically look straight at the camera, or focus on some object behind the camera. And since blind people don't see where the camera is, their eyes sometimes (often) appear to be looking unfocused. You can't tell where their gaze goes because they are not gazing at anything. This is what the two photos (this one and wikipedia) look like and why I was curious.
