Our eyes work as a camera does. They send the pictures we feel surroundings to the brain. Thats to say, it is our brains that figure out what our eyes see around us, which works from the very time you open your eyes to close your eyes.
It is almost the same as how a camera works. When light rays from each substance that passes through the lens get recorded on a computer chip or film, the light passes through our eyes and it gets recorded at the back of our eyes or the retina.
Although the picture recorded by the camera as well as our eyes are both reversed or inverse, once the information is sent to the brain, it turns it at once and tells you what sort of object you are watching.
Constitution of the Eye
The eye consists of different parts that cooperate together. The white part of eyes is the sclera, a sturdy skin sheltering of the exterior part of the eyeball. The part clear as crystal with no blood vessels inward is the cornea, a transparent skin sheltering the fore part of the eye.
The colored part of the eye is iris that masters the number of light going into the eye. And then the lens is in charge for concentrating the light onto the retina. It can change its shape to assure that the picture within the retina is patently reflected.
The hole inside the colored Iris is pupil which lets the light enter your eye and becomes very small in bright ray and becomes bigger in dark places. Another part of the eye is retina that is almost the same as a "movie screen" that displays the picture you look at but reverse. It is made up of many two-typed cells, the "cones" and the "rods." The ones that see the colors are cones while the ones that see black and white are rods .They are the ones which convert the picture intoelectrical information" for the brain.
Another important part is optic nerve. As soon as the Retina sends out the electrical messages, it gets to the optic nerve and then to the brain. Eyelashes and eyelids work as a shelter for the eyes. The eyelids exclude the ray to assist in you sleep. They will even close quickly once they feel something uncomfortable trying to enter into the eyes. Eyelashes are also very responsive. As the eyelids shut, they prevent the dust from permeating into the eyes.
Tear glands locate in the upper eye lid. It makes tears to maintain the eyes watery and clean. They shelter the eye from hurt. When we blink, the eyelids shed tears over the surface. Small things like particle get cleaned into the corner of the eye next to the nose.
Eyebrows prevent the sweat and particles from the eyes. The conjunctiva is the lining on your interior eyelid and the front of the eyes' exterior portion, where there are puny blood vessels that become bigger when the eyes are sore and appears red.
