It is good to know, that a cat vision is 6 times better than human in night.It is a huge difference between cat vision & human vision is in the retina.In a human at the back of the eye has a layer of tissue, it contains cells, which is called photoreceptors. It.It convert light rays into electrical signals by nerve cells & sent in our brain to translated a image that we see.But the cats have contain a high concentration of rod receptors and a low concentration of cone receptors. It have the opposite of humans,so thats why we can’t see better than a cats vision.But we detect the color better than a cat.
