Mine eyes are usually normal. Sometimes they are not. You probably figured that out already from the color scheme here. Sometimes the lights are too bright, usually when I'm dehydrated. I've been told it's because of my autism. There are times when they don't work right in the other direction, except "the other direction" implies when this happens it's the opposite, that the lights aren't as bright, and I can't see properly. They stay the same brightness.
