I have the same, but a thought crossed my mind that it somehow stimulates your vision so that you start seeing the flickering which is always there

I got quite intense distorted vision after perusing this for a while. Trippy!

I felt like I was going to have an ocular migraine after looking at that for a few seconds.

I cannot unsee this. My eyes are going to hurt for a while from the moving background.

Am I the only one who sees bright horizontal lines while my eyes are closed, after looking at this article for a minute or two?

This is not an optical illusion. It is akin to movies' special effects as best. I wonder what human sight frequency is and is there a way to alter it?

Are you sure it's your backlight and not your eyes? (Something like this: https://en.wikipedia.org/wiki/Motion_aftereffect)

My vision was distorted for full 30 seconds after reading this page.

What are these like for people with epilepsy or other sensitivities to rapid visual strobing?
