The human eye is an organ that allows us to see. It does this by detecting light and converting it into electrical signals, which are then sent to the brain. The eye is made up of several parts, including the cornea, the iris, the pupil, the lens, the retina, and the optic nerve.
The cornea is the clear, dome-shaped surface at the front of the eye. It helps to focus light as it enters the eye. The iris is the colored part of the eye that surrounds the pupil. The pupil is the black circle in the center of the iris, and it adjusts in size to control the amount of light that enters the eye.
The lens is a clear, flexible structure that sits behind the pupil. It helps to focus light onto the retina, which is a thin layer of light-sensitive cells at the back of the eye. The retina converts the light that it receives into electrical signals and sends them to the brain through the optic nerve.
The brain then processes these signals and interprets them as images. This process occurs almost instantly, allowing us to see the world around us in real-time
