The human eye can be compared to a camera as both works by gathering focusing and transmitting the light through the lens for creating an image of an object. The lens is a clear part of the eye behind the iris that helps to focus light or an image on the retina.
The macula is the small sensitive area of the retina that gives central. Structure of Human Eye. A human eye is roughly 23 cm in diameter and is almost a spherical ball filled with some fluid.

Our eyes detect light. The two eyes are positioned so that each one gives a slightly different view of your surroundings. This gives us a Binocular Vision.
Each eye produces an image or picture of what you are looking at. Information about the image in each eye is then sent along a nerve to your brain. The human eye can detect over 10 million colors but it cant detect ultraviolet and infrared lights.
Our eyes focus on about 50 different objects every second. It is impossible to sneeze with your eyes open. The optic nerve contains more than a million nerve cells.
We actually see with our brain and not our eyes. Let us study how the human eye uses light and enables us to see objects. Eyes are the most valuable organ of the human body which process the images of objects in the vicinity.
The eyes interpret size shape colour and distance of the objects and give a 3D picture of the objects visible. The eyes are seated in a hollow cone shaped cavity. Eye function renders you the sense of sight.
They convert light into electrical signals. Afterwards the brain deciphers these electrical signals into images. Properly working healthy eyes are able to perform the following functions.
It is one of the important human eye facts that they help us view our surroundings. Our eyes enable us to see colors. The optic nerve is what conveys the signals of the eye to the brain.
Is a diagram of the eye. The human eye is made up of three coats. Diagram of the Human Eye.
The cornea and lens of an eye act together to form a real image on the light-sensing retina which has its densest concentration of receptors in the fovea and a blind spot over the optic nerve. The central artery and vein runs through the center of the optic nerve. The central artery supplies the retina while the central vein drains the retina.
In the diagram above - anatomy of the eye the artery is shown in red while the vein is shown in blue. The eye one of the most complex organisms in the human body. In order for the eye to work at its best all parts must work well collectively.
To understand the eye and its functions its important to understand how the eye works see below diagrams for both the external eye and the internal eye.

The anatomy of the eye includes auxiliary structures such as the bony eye socket and extraocular muscles as well as the structures of the eye itself such as the lens and the retina.
The human eye is a simple eye 77 The outermost of the three coats of the eye consists of cornea limbus and sclera 78 The middle coatthe uveal tractincludes the iris ciliary body and choroid 78. Structure and Function Clyde W. Eyes are approximately one inch in diameter.
Pads of fat and the surrounding bones of the skull protect them. The eye has several major components. The cornea pupil lens iris retina and sclera.
Anatomy parts and structure. The eye is the photo-receptor organ. Human eye is spherical about 25 cm in diameter.
It is situated on an orbit of skull and is supplied by optic nerve. There are 6 sets of muscles attached to outer surface of eye ball which helps to rotate it in different direction.
