This type of post is highly unusual both in it's content and presentation.

Whether the incidents you describe are real or not, it's fairly evident that you're experiencing intense psychological consequences, and I urge you to seek some form of professional help.

What you are describing is worryingly consistent with the types of delusions paranoid schizophrenics experience, and the onset of schizophrenia can be specifically heralded by sudden changes in vision and other optical abnormalities. I've spent a lot of time around people struggling with schizophrenia, as it runs and my family and I have a few friends who suffer from it as well. I think it is very much worth your time to see a professional about all of this.

Best of luck.
