Vision is an intricate process that enables the sense of sight. Our eyes allow us to admire the beauty of the world, experience the pleasure of learning new activities, and undertake new adventures. It is one of the five main senses and plays a crucial role in the way most people perceive the world around them. Vision, or the act of seeing itself, does not occur in your eyes. Instead, it's the sum of your eyes, retinas, optic nerves, and brain working together to process reflected light from the environment around you.
