The eye is one of the five senses, which is the property of Humana. Eye as a visual sense plays an important role in a response or encouragement regarding the reception acknowledge observe and describe the state of the visual environment.
To work, one of the major human senses require the presence of light as a stimulus. This is because the eye functions as a tool, optics uses light work. The human eye can see objects because of their specific process.
This method is described by the simple operation of the light. Where the light entering the rebound object, and the light of the object is detected by the eye.Light that the eye is detected and processed in the brain.
In the process, the light of this, many parts of the capture – the members of the affected eye with a private function – even learn about the game -. Of the eye and its function, it is important.
Generally, the sclera of the eye 4 or parts of the outer membrane or coating of the choroid, retina or the retina and the lens of the eye. However, part – eyes still smaller parts. As in the sclera, cornea and no liquid and portions of the choroid, the iris and pupil there.
For more information, the following explanation of the parts – parts of the eye and its main function.
The cornea of the eye is one of the anterior portion of the sclera and the outermost portion of the ocular element. Because it is in the outermost position of the eye, the cornea also has the characteristics of a solid and translucent. Korena functioning eyes to the light and directs the light into the eye and enters the inside of the eye.
The light, which is obtained from the corneal retina.Selain finally approved the cornea as the outermost part of the eye is also a tool for protecting sensitive parts of the eye to the provision, are discussed below.
- Aqueous humor
Aqueos humor is part of the liquid lens and cornea of the eye. This segment of the eye is the light within the break of the eye.
- Crystalline lens or eye
The lens or lens of the eye is also known as playing an important role in the regulation of the position of the shadow falling directly on the retina yellow spots on paper. be able to establish whether this shadow objective eye using mencembung muscular and flattened silirsis. mencembung and flattened eye is known as the power of accommodation.
Iris is the eye’s mucous membrane, which are formed in the middle of a circular groove. Iris is the size enlargement or the student set. Conditions pupil magnification is done to limit the amount of amount of light that can penetrate the iris of the eye, so that the intensity of light, given the right eye accepted.
The arrangement of the iris is located in the center of the eyeball, and directly behind the cornea. In addition to meeting the amount of light which is instrumentally Iris provision color.That eyes thus the iris and the iris is known.
Since the iris and a color ball may seem to have a black eye, brown, blue or green, the color differences of the iris is due. Differences in color of the iris is generally influenced by differences of race or nationality.
The pupil is the eye that a deviation because of the size of iris.The function of distance or student activities is the real space in the path of the light entering the eye is form.
Thus, the function of the pupil can be considered as a fixed amount of light for the eye occurs. function of the pupil is substantially similar to the membrane function in optical devices such as cameras. shaped groove of the round shape of the pupil, which is exactly in the middle – the middle of the iris.
- The eye muscles
The extraocular muscles are part of the eye that serves to regulate the large and the small lens of the eye. In addition, the eye muscles also act as a buffer lens.
Vitreous is a part of the eye, as a clear liquid cargo orbital sebagap look. The function of the glass body consists of transmitting the light from the lens onto the retina.
The retina is a layer on the back of the eyeball. This is a shadow on the causes of the retina of the incident light, is prepared. Therefore, the retina of the eye is very sensitive to light and very soft.
Retina has a primary function as a light trap, which is then transmitted to the optic nerve. Then, the light eventually receive – the nerve endings are located in the retina. Retina sometimes called the retina.
- In the retina, there are parts which are:
- Stem cells (rod), a part of the retina in order to mitigate the stimulating light are sensitive
- Cone (cone), a part of the retina to bright light stimuli are sensitive
- The blind spot (Blind Spot), a part of the retina where membeloknya nerve fibers leading to the nerve center
- yellow Binting (the fovea), a portion of most mengadung neurons visionaries retina as the shadow formation. In the retina yellow spots, they are more sensitive to light.
- Filling the fluid cavity consisting of an aqueous fluid or of the humor between the cornea and the lens and vitreous or liquid between the lens and retina.
- The optic nerve
The optic nerve of the eye used by the retina to light stimuli in advanced brain. The optic nerve was instrumental in bringing all the information is processed in the brain, until we can finally see an object or an object.
