Episode 7: The Eye and Colour Vision




The Wonder of Reality show

Summary: Welcome to the first episode of Miniseries 2 "How Humans are Fallible". Once we finished the first miniseries "What is Science and How Does It Work?" we realized that the biggest issue we have with conducting and understanding science is being human. To start our discussion on how humans are fallible we talk about how we see colours. How do computer monitors trick us into seeing most colours? Are their colours that do not exist in the rainbow? How does our vision change at dusk? See it for yourself by clicking below (video stream sold separately). Corrections/Clarifications: In saying that we would only see one minute of footage every hour, we made a few assumptions. Read through all our calculations here When saying that we could only see from 400 to 700 nanometers, we skipped that some parts of our eye including the lens can block ultraviolet light though we could still perceive it if it made it to our retina: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1860240/ Links: Read our Show Notes on Caring for your Human, Cone Sensitivities, How Cones Work Together to See Colour, Colourblindness, and How Rods Work NASA's discussion on the entire electromagnetic spectrum The visible spectrum and colours Cones and colour reception Why men are more often colourblind than women A technical discussion on colourblindness and camoflouge detection The genetics of passing on colourblindness or any other X chromosome disease Deuteranopia Some woman have four rods and can see 100 million colours Cones vs Rods More information on Rods and Cones
