The symbol "👁️" represents an eyeball, the organ responsible for vision in humans and many animals. It is a spherical structure that contains various components, including the iris, pupil, and sclera. The eyeball captures light through the cornea and lens, which focus the incoming rays onto the retina at the back of the eye. The retina then converts the light into electrical signals that are transmitted to the brain via the optic nerve, allowing us to perceive the world around us visually.
