It is the outer covering a protective tough white layer called the sclera white part of the eye. The eyes are seated in a hollow cone shaped cavity.
Figure 24a shows a perfect eye diagram.
Internal structure of eye diagram. Anatomically the eye comprises two components fused into one. Hence it does not possess a perfect spherical shape. External components include structures which can be seen on the exterior of the eye and internal components include structures present within.
The cornea is the clear outer part of the eyes focusing system located at the front of the eye. The iris is the colored part of the eye that regulates the amount of. The Accessory Structures of the Eye.
These include the eyebrows the eyelids and eyelashes the conjunctiva and the lacrimal apparatus. These are two arched eminences of skin surmounting the supraorbital margins of the frontal bone. Numerous hairs project obliquely from the surface of the skin.
Structure Of Human Eye Diagram Human Eye. Anatomy parts and structure. The internal components of an eye are.
The eye has six muscles which control the eye movement all providing. The cornea is the transparent part of the eye that covers the front portion of. It is a transparent biconvex lens of an eye.
The sclera provides the eye with structural strength and protection. Here are descriptions of some of the main parts of the eye. The cornea is the clear outer part of the eyes focusing system located at the front of the eye.
The iris is the colored part of the eye that regulates the amount of light entering the eye. The lens is a clear part of the eye. Click the parts of the eye to see a description for each.
Hover the diagram to zoom. The iris is the coloured part of the eye which surrounds the pupil. It controls light levels inside the eye similar to the aperture on a camera.
The iris contains tiny muscles that widen and narrow the pupil size. Diagram of the different layers of the eyeball. The outer fibrous layer maintains the shape of the eyeball and protects more fragile internal structure.
This layer is made up of the sclera and cornea. The sclera is the firm opaque outer part of the eye commonly referred to as the whites of the eye. It covers most of the outer surface of the eyeball.
A human eye is roughly 23 cm in diameter and is almost a spherical ball filled with some fluid. It consists of the following parts. It is the outer covering a protective tough white layer called the sclera white part of the eye.
The front transparent part of the sclera is called cornea. Light enters the eye through the cornea. An eye diagram provides a simple and useful tool to visualize intersymbol interference between data bits.
Figure 24a shows a perfect eye diagram. A square bit stream ie series of symbol 1s and 0s is sliced into sub-bit stream with predetermined eye intervals ie several bit periods and displayed through bit analyzing equipment eg digital channel analyzer overlapping. The eye diagram takes its name from the fact that it has the appearance of a human eye.
It is created simply by superimposing successive waveforms to form a composite image. The eye diagram is used primarily to look at digital signals for the purpose of recognizing the effects of distortion and finding its source.

The Surface of the Eye. The surface of the eye and the inner surface of the eyelids are covered with a clear membrane called the conjunctiva. The layers of the tear film keep the front of the eye lubricated.
Tears lubricate the eye and are made up of three layers. Central Artery and Vein. 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 act of seeing is a complex process that depends on 1 light from the outside world falling onto the eye 2 the eye efficiently transmitting and properly focusing the images of these objects on the retina 3 the retina detecting these light rays 4 transmission of this information via the visual pathways to the brain and 5 the brain processing this information so as to make it useful. 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. The inside of the eye contains the two refractive structures of the eye called the lens and vitreous body.
Together with the cornea and aqueous humor the vitreous body and lens belong to the refractive media of the eyeball. The role of refractive structures to bend the direction of the light that falls onto the eye and focus it onto the retina. The structure of eye comprises three coats within which further are three transparent structures.
The outermost layer or the fibrous tunic consists of the cornea and sclera. In the middle layer we have the vascular tunic or uvea consisting of the choroid ciliary body and the iris. Structurally two eyes are separated but some of their activities are coordinated so that they functions as a pair.
Anatomical structure of Eye. Eye ball consists of three layers. Sclera cornea and conjunctiva.
