Afterimages & Colour Vision

In this experiment, we learn about afterimages and why we see them. Our eyes contain specialised cells called cones and rods. Rods help us see in low light, but they can’t see colour and have difficulty seeing fine details. There are three types of cones, corresponding to red, green, and blue light wavelengths, which allow us to see colour. When we stare at something for a while, that can tire our cone cells. While those cells are recovering, they’re not contributing to our regular vision as much, which results in us seeing an afterimage. Try this experiment out in the video! You can even try it with one eye closed and then switch between your eyes when looking at the white screen. Pueblo Science is a Toronto-based charity dedicated to advancing science education and developing alternative teaching kits that are engaging and fun for children, while still being inexpensive, and can be locally reproduced by science educators in underserved communities around the world. This video was made with the support of the Ontario Trillium Foundation.
