Beyond 20/20: Exploring the Limits of Human Vision and Beyond

The video explores visual acuity, starting with a basic understanding of 10 tenths vision and how some individuals, like fighter pilots, can have superior vision. Mac Lesgie undergoes a vision test, revealing the need for new glasses. The video then delves into the exceptional vision of fighter pilots, who can achieve 12 tenths, and discusses the potential for even greater acuity, up to 25 tenths. The video also highlights the extraordinary vision of vultures and the concept of tetrachromacy in birds, which allows them to perceive a broader color spectrum than humans.
