<\/span><\/h2>\n\n\n\nThe eyes can see because light bounces back into the pupils when light hits an object. Both humans and animals have these specialized nerves called photoreceptor nerves. <\/p>\n\n\n\n
Photoreceptors are responsible for “translating” the object to the brain. And thus, you can “see” the world around you. So, there are two types of photoreceptors: rods and cones.<\/p>\n\n\n\n
Rods are light-sensitive; they detect the amount of light (amplitude) in a grayscale of black and white. Cones are responsible for detecting the color of the light (frequency.) They can detect Red, Green, and Blue (RGB) lights of varying intensity. There are more rods (120M) than cones (6M).<\/p>\n\n\n\n
Rods are also slower to adapt than cones. That’s why when you enter a dark room; your eyes take longer to adapt to the darkness. But you can detect colors quicker.<\/p>\n\n\n\n
