Los ojos de gato

Percy, inspired by a cat's reflective eyes, invented cat's eyes for roads to improve night driving visibility. His design involved crystal balls with a reflective backing, which reflected car headlights back to drivers. To maintain clarity, he created a self-cleaning mechanism using rainwater. This invention, largely unchanged for over 80 years, is used worldwide, enhancing road safety and saving lives.
