from TED-Ed · host TED-Ed
Explore the science of afterimages, which are the visual illusions that appear in the eyes after exposure to an image or bright light.--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.Lesson by Paul Taylor, directed by Sofia Pashaei.Support Our Non-Profit Mission----------------------------------------------Support us on Patreon: http://bit.ly/TEDEdPatreonCheck out our merch: http://bit.ly/TEDEDShop----------------------------------------------Connect With Us----------------------------------------------Sign up for our newsletter: http://bit.ly/TEDEdNewsletterFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagram----------------------------------------------Keep Learning----------------------------------------------View full lesson: https://ed.ted.com/lessons/what-are-those-colors-you-see-when-you-rub-your-eyes-paul-cj-taylorDig deeper with additional resources: https://ed.ted.com/lessons/what-are-those-colors-you-see-when-you-rub-your-eyes-paul-cj-taylor/digdeeperAnimator's website: https://www.instagram.com/sofiapashaei----------------------------------------------Thank you so much to our patrons for your support!
