This answer is not easy but if you really want to get into it... the eye is an organ which reacts to light for several purposes... Light comes in through the cornea, a clear tissue that covers the front of your eye. The pupil is the dark spot in the middle of your eye. It works like a camera shutter, controlling the amount of light that enters our eyes. When it's dark, the pupil dilates, or widens. When it's bright, the pupil gets smaller. Surrounding the pupil is the iris. This is the colored ring of muscle fibers that help the pupil change size.
When you look at an object, light rays enter your eyes. These light rays are bent and focused by the cornea, lens, and vitreous. The vitreous is a clear jelly-like fluid that fills the inside of your eye. The lens' job is to make sure the rays come to a sharp focus on the retina at the back of the eye. Think of the retina as the film in the camera. It's lined with light-sensitive cells, called photoreceptors, that capture, upside-down, the images in our visual field. The sensitive macula, critical for sharp focus, is the most active part of the retina. A healthy macula helps us read small print and see the images in our direct line of vision. When light rays reach the retina, they're converted into electrical pulses that travel through the optic nerve to your brain. It is there that the image gets flipped right-side up. lol if that's not enough then read a book!
