TED-ED: The evolution of the human eye - Joshua Harvey

The video explores the evolution of the human eye, starting from simple light-sensitive spots in single-celled organisms to the complex structure we have today. It highlights the development of the pinhole eye and the crucial role of the lens in enhancing vision. The video also discusses the imperfections in the human eye, such as the inverted retina, and compares it with other species' adaptations. Finally, it touches on the potential for designing biomechanical implants to improve vision, inspired by various eye structures in nature.
