If you're referring to the objects in the centre of the road - that are sometimes called cats eyes, then it's reflected light.
No cats were harmed in making them.
Yes, Cats eyes, are 'cats eyes' although their eyes aren't the same as maybe the marble 'cats eye', only in bright light- i suppose they are just eyes though
Cats eyes expand at night because They are bringing in more light to see into their eyes
yes
The cats eyes reflect the light.
well they eyes are like our eyes they can get blind
Because there's no light reflecting at the cat's eyes.
Cats' eyes have a reflective layer called the tapetum lucidum that helps them see better in low light. In the dark, their eyes may appear to glow or shine due to this layer reflecting incoming light. Their pupils also dilate to let in more light, giving them better night vision.
When cats are sleeping, their eyes roll back because it helps protect their eyes and keep them moist. This is a natural reflex that helps keep their eyes healthy while they rest.
Yes, that is their purpose.
No. In the dark, the eyes of animals, especially animals that are nocturnal, will reflect light and look like they glow. This is the same thing that causes your eyes to "glow" red when someone takes a photo with a flash.
they reflect the light using the law of incidence
because they have sharp eyes .
