ClÃnica Baviera: How does the eye work?
The size of a golf ball, the eye is made up of a complex system of connections and electrical pulses with the brain, and is one of the body’s main points of contact with the outside world.
It works like the shutter on a camera, controlling the quantity of light that enters the eye and dilating or contracting.
The cornea works as its objective, allowing the light to go through. Behind it, we find the iris that controls the amount of light that enters the eye, like the diaphragm of a camera.
Behind is the crystalline that, like an optical zoom lens, allows to focus the images.
It works like the shutter on a camera, controlling the quantity of light that enters the eye and dilating or contracting.
At the bottom of the eye is the retina that acts like a photographic film, where the light is printed, it is then transformed into nervous impulses and sent to the brain through the optical nerve where the images are developed.
The inside of the ocular globe is filled with a liquid named “vitreous” that allows the eye to keep its shape.
