What are eyes?

Eyes are organs that detect light and convert it into electrochemical impulses in neurons. They allow organisms to see and perceive their surroundings. Eyes come in various shapes and sizes, and they are found in many different types of animals, including humans. The human eye is a complex organ that consists of several parts, including the cornea, iris, pupil, lens, retina, and optic nerve.

Eyes are sensory organs that allow us to see. They are complex structures that contain many different parts, including:

- Cornea: The clear, dome-shaped outer layer of the eye.
- Iris: The colored part of the eye that controls the size of the pupil.
- Pupil: The black hole in the center of the iris that allows light to enter the eye.
- Lens: A flexible structure that changes shape to focus light on the retina.
- Retina: A thin layer of tissue at the back of the eye that contains light-sensitive cells called rods and cones.
- Optic nerve: A bundle of neurons that carries visual information from the retina to the brain.

Eyes work by focusing light on the retina. The retina contains millions of rods and cones, which are cells that convert light into electrical signals. These electrical signals are then sent to the brain through the optic nerve, where they are interpreted as images.
