Fun Facts About Your Eyes

Fun Facts Daily

About this episode

Discover the astonishing capabilities of the human eye and the powerful brain that processes what we see. Learn how the world is projected upside-down onto our retinas and how the brain's visual cortex flawlessly flips the image right-side up. The eye's perception of color is made possible by three types of cone cells, which allow the brain to distinguish between an incredible 10 million different hues. Delve into fascinating biological quirks, such as the natural blind spot in each eye that our brain cleverly conceals, and the intricate patterns of the iris, which contain 256 unique characteristics, making it more secure for identification than a fingerprint. The muscles controlling eye movement are the fastest and most active in the body, performing over 100,000 movements each day. Learn about the fascinating phenomenon of synesthesia, where one sense triggers another so allowing a person to hear colors or taste sounds. Finally, for those experiencing digital eye strain, the simple and effective "20-20-20 rule" is presented as a practical way to give our hardworking eyes a much-needed break.
