What are those colors you see when you rub your eyes? | Paul CJ Taylor

In the 1600s, Isaac Newton conducted a series of experiments to better understand the lights and colors that sometimes appear when your eyes are closed. If you’ve ever sat around an evening campfire or unintentionally glanced at the Sun, you may have noticed illuminated patterns briefly dance along your vision. So how do these visual illusions form? Paul Taylor explores the science of afterimages. [Directed by Sofia Pashaei, narrated by Alexandra Panzer, music by Cem Misirlioglu, WORKPLAYWORK].
