The light-sensitive membrane that covers the back of the eye is known as the retina. The cornea, iris, pupil, and lens make up the front of the eye, which focuses the image onto the retina. They focus on the light that's reflected in their eyes. The way your eyes work is similar to how a camera does. We learn 80% of what we know through our senses of sight. We can be aware and see beautiful things around our environment, thanks to our vision. The eyes of all mammals have a non-image-forming photosensitive ganglion in the retina which receives light, adjusts the size of the pupil, regulates the supply of melatonin hormones, and also entertains the body clock. The human eye is a part of the sensory nervous system. The human eye can differentiate between about 10 million colors, and it can also detect a single photo. rods and cones.Ĭonscious light perception, colour differentiation and perception of depth are done by these cells.
