How Do Our Eyes Work?
“The eye is the window to the soul.” When you first meet someone new, the first thing you typically notice is their eyes. The eyes are one of the most powerful organs in the human body. They allow you to bring objects into focus so you can process and perceive the world around you. Have you ever wondered how the eye works? Our team at Eye2Eye Optometry has the answers you’ve been looking for in this helpful guide below.
What is an eye?
As mentioned above, your eye is an organ that allows you to see the world around you. An eye consists of many parts that help bring objects into focus, so you can process what you’re seeing. Once an object comes into focus, your eye carries a message to the brain, which then communicates what you are seeing.
How does the eye work?
The eyeball has many components and layers that all work together to help you see. Here is a general outline of how the eye works:
-
Cornea: The very front layer of your eye is called the cornea. This clear layer is dome-shaped and the first place that light passes through your eye. The cornea is responsible for bending the light you see to help your eye focus.
-
Pupil: Your eye also contains a pupil, which is an opening that allows some light to enter your eye. This is the dark circle in the center of your eye that expands and contracts when light shines on it.
-
Iris: The part of your eye that contains color is called the iris. Humans can have varying iris colors, including brown, blue, and green. The iris works with the pupil to decide how much light to allow into your eye.
-
Lens: Light then passes through the lens, which is the inner part of your eye. This clear part of your eye works with the cornea to focus light in your eye.
-
Retina: The light then makes its way to the retina, which is the sensitive layer of tissue in the back of your eye.
-
Photoreceptors: Your retina contains photoreceptors, which are cells that turn light into electrical signals. These cells need to find their way to the brain to process the light you are seeing.
-
Optic Nerve: The photoreceptors start at the retina and travel through your optic nerve, which is a channel to the brain. Your brain then processes the objects you are seeing.
