How many cats eyes on the road are there in the world - would there be more cats eyes than human eyes?
Cats' eyes on the road, commonly known as cat's eyes or road studs, are used as reflective road markers for safety. While it's impossible to determine the exact number of cat's eyes in the world, estimates suggest there are millions installed globally. Given that there are approximately 8 billion humans with two eyes each, it’s likely that there are far more cat's eyes than human eyes. Thus, yes, there would generally be more cat's eyes than human eyes.

The number of cat's eyes (reflective road markers) per mile of road can vary based on local regulations and road design. Typically, they are placed every few feet along the road, often around 100-150 feet apart in some regions. This can result in approximately 320 to 528 cat's eyes per mile, depending on the specific spacing used.

How are cats eyes linked with road safety?
Cat's eyes are reflective markers on the road that help improve nighttime visibility for drivers. They have a design similar to a cat's eye, with a reflective surface that bounces light back towards the driver, making road markings and hazards more visible in low light conditions. This helps drivers stay in their lane and navigate safely, especially in areas with poor visibility.

On the motorway how do cats eyes help drivers to see at night?
Cat's eyes on the motorway are actually tiny little reflectors inset into the pavement to reflect the car's headlights back at the driver. They are called that because they reflect light back just the way eyes of real cats do; if a cat is looking at you, and you shine a light at it, the cat's eyes will reflect the light back. The main thing that cats eyes on the motorway do is provide a clearer indication of where the motorway lines are. The reflection from a cats eye embedded in the road is much more visible than the line painted on the road and can be seen at a much greater distance. Cats eyes of different colours give the driver lane separation, and early warning of slip roads, hard shoulders, median edge, danger areas etc

What are cat eyes?
Cat's eyes are reflectors that return light that falls on them back to the light's source. Often they are inset into roads to show road edges and lane markings. They get their name from the eyes of cats, which have a reflective layer behind the retina; this enhances the cat's night vision by passing the light back through the retina, effectively doubling it. At the same time, it makes the cat's eyes seem to glow if you look at a cat with a light behind you. It is this reflection of the light directly back at you that inspired the name for the reflectors.
