The functions of the parts of the eye and disorders that occur in the eye
The functions of the parts of the eye and disorders that occur in the eye - The eye is the sense of eyesight is essential for human life, so it is important to know the function of the part of the eye that plays a role in shaping the vision of our sensory system. The eye is one organ that is very amazing because it is the natural optical device which makes a man can see the objects and the beauty that exists in the world. In General, the eyes have a function to capture light, distinguish between light and dark, distinguish the intensity of different colors, and give a sense of the visual appearance of an object against the arrested. If the eyes are misbehaving, then certainly it would be very distracting and can lower the quality of life of a person.
The eyes have many parts and all parts have their respective functions. The eye consists of the outside and the inside. The outside of the eye inevitably we all already knew him, like eyebrows, eyelids, eyelashes, eyes, muscles, and glands. While the inner part of the eye between the cornea, other aqueous humor, iris, pupil, lens, vitreous humor, ciliary muscles, retina, optic nerve, and yellow spots. In principle, the workings of the eye that is capturing objects in front of the eyes with the help of light, focusing light, adjust the amount of light, converting light into electrical impulses, and sends electrical impulses to the nerve center of vision in the brain the impulse to interpret them as images.

Stem cells function captures the light in black and white and seeing in dim light, while cone cells serve to capture light that is colorful and bright in view.
Eyelids on duty to open and close my eyes as needed, protecting the eyeball, and regulate the intensity of light. eyelashes serve to protect eyes from foreign objects, such as dust and sand. Eye muscle function for moving the eyeballs, well to the right, left, top, or bottom. Whereas the gland tear function to produce tears to moisten the eye while cleaning the eyes from dirt and germs.

The function of the Part of the eye in the sensory system Vision
Our eyes are composed of complex parts. If one part is damaged or having the disorder then can disrupt our vision system. In some cases, even damage to a vital part of the eye can cause a person can not see or experience blindness. Therefore any part of this eye we should keep its functions remain optimal. The functions of the parts of the eye, among others, as follows:Sclera
Sklera it is part of the white of the eye that surrounds the cornea. Sklera consists of a fibrous network that serves to provide protection to the inside of the eye. In the eyes of people who are healthy, bright white colored sclera. If you're having an especially disease disorders that are associated with impaired liver function, sclera it can turn into yellow.The Cornea
The cornea is the transparent tissue on the front of the eye that receives light from an object enters the eye. The functions of the parts of the eye cornea i.e. help focus light on the retina.Read too: Know the benefits and efficacy of Cucumber for the incredible Eyes
Aqueous Homor
Aqueous humor or often referred to as the home front it is a clear liquid/transparent that fills the space between the cornea and lens of the eye. Aqueous humor functions to supply oxygen and nutrients to all part of the eye.IRIS
IRIS is a part of the eye that is a circular/ring in the middle of the eye. The function of this part of the eye that is to regulate the amount of light that enters the eye in a way set the size of the pupil.Pupil
The pupil is a hole in the center of the iris that function to adjust against the amount of light that goes by means of enlarged or decreased. The pupils dilate and the SAGs is controlled by the iris.The lens of the eye
The lens of the eye is part of the eye that is located right behind the pupil. The function of the part of the eye is to focus the light so that the right falling exactly on the retina.Muscle Ciliary
Siliari is a muscles tissue resembles a ring that surrounds the lens of the eye and served to control the shape of the lens. So it had a ciliary muscle function to regulate or control the movement of the lens of the eye.Vitreous humor
Vitreous humor is a liquid that fills the space between the lens and the retina of the eye. Vitreous humor this is a fluid that fills most of the part of the eye which is about two-thirds of the entire volume of the eye. Eye vitreous humour section function is to protect the lens of the eye.Retina
The retina is the part of the eye-shaped membrane which serves to change the light that has been focused by the lens of the eye, into the impulse/electrical signal to be sent to parts of the brain. It had a retinal cell of photoreceptors that are very sensitive to light. These photoreceptors cell consists of two types: rods and cones.Stem cells function captures the light in black and white and seeing in dim light, while cone cells serve to capture light that is colorful and bright in view.
Yellow spots
Yellow spots or often referred to as the macula is a part of the eye that is located in the retina are most sensitive to capture incoming light so that produce electrical impulses. So any light from the object was captured right in the yellow spots then the object would be clearly visible.Optic Nerve
The optic nerve is the nerve fibers that connect the eye with the brain. The function of this part of the eye that is to transmit impulses/electrical signals from the retina to the brain in order to interpret visually against the object seen.The outside of the eye
In addition to the inside of the eye, we also had the outside of which also have an important role. They are namely the eyebrows, eyelids, eyelashes, eyes, muscles, and glands. Eyebrows serve to retain water or sweat from hair or forehead in order to not get into the eyes.Eyelids on duty to open and close my eyes as needed, protecting the eyeball, and regulate the intensity of light. eyelashes serve to protect eyes from foreign objects, such as dust and sand. Eye muscle function for moving the eyeballs, well to the right, left, top, or bottom. Whereas the gland tear function to produce tears to moisten the eye while cleaning the eyes from dirt and germs.
Disorders of the Eye Functions that need to be controlled
Our eyes can experience various disturbances so as to make the eyes may not work optimally. The disorder can be either a deformed eye suffered since birth or due to poor lifestyle factors, accidents/trauma, infection or disease germs. Malfunctioning of the eyes that often occurs among others as follows:Cataracts
Meruapakan eye disorders cataract be blurry sight caused due to thickening on the lens of the eye. This condition is common in elderly people.Nyctalopia
Nyctalopia is a disease of the eye in which the sufferer experiencing eyesight trouble happens when afternoon/evening only. This condition usually due to vitamin A deficiency.Color blindness
Color blindness is an eye disorder in which a person experiencing interruptions in interpreting the color of an object. Color blindness can occur in total (all colors just look black, white, and gray), or partially occurs (cannot distinguish certain colors only). Color blindness is usually caused due to genetic factors/offspring.
Eye refraction disorders
The eye refracts is disruption on the eyes where a shadow object that is caught is not right on the retina or even cannot be completely captured by the retina. There are several types of this disorder, such as myopia (cannot see remote objects), hypermetropia (cannot see objects up close), and presbyopia (can't see objects far or near).
Low vision and blindness
Low vision and blindness are usually obtained from birth or may be due to the accident. Low vision means a person can only see vague, while the blind that is not can be viewed in total.
After knowing the functions of the parts of the eye as well as disorders of the eyes as explained above then certainly we realize how important eye for human life so that should we really keep. To maintain the health of the eye, it can be done, among others, i.e. with sufficient vitamin A needs, read a book at a distance and illumination is sufficient, not very long in front of the TV or the computer, protect eyes from foreign objects, ingress and keeping the eyes of the collision/trauma.
You should immediately consult a doctor when experiencing complaints on the eyes, among others, IE painful on the eyes, great view of the sudden blurred, there is a sensation of foreign object in the eye, red eye accompanied by headaches or nausea vomiting, seeing as flicker/flashing lights, see the spots or black strands that float, such a view is obstructed by something, eyes that stand out, there is a lump in a difficult eye healed, or suddenly there arose a view double.
