By the time your child gives color “should not be” on the picture or in coloring books, you should not upset because that’s what kids should do as the instructions to his creativity or your child to freedom of expression. But it also needs to watch out because he might be color blind.
The facts show that 10 million people in America have a problem with color vision. 1 of 12 men in the United States was experiencing it while it was affecting 1% of women in Uncle Sam’s country. Most of the causes of color blindness is a genetic mutation or other reasons such as aging, glaucoma, cataracts or effects of certain medications.
Color blindness affects one in 25 children with 3 main types:
1. Red-green blind: this is the most common type. Difficult to distinguish between red-green color.
2. Yellow-blue blind: difficult to distinguish between blue yellow coloring.
3. Do not see colors: This condition is very rare and usually only see black, white and gray.
So what is the cause of color blindness? In the retina there are millions of cones that allow us to see light and color. There are three types of cones that will about them to light of different colors, red, blue or green. If there is damage to one type of cone is that will cause a mild color blindness. If there is one type of cone is missing, then the color-blindness would be more severe.
There are several ways to tell if your child color blind. Because a child who has color blindness will do the following things:
* Seeing the color, especially the primary colors, with the name of the wrong color.
* Create an image that does not fit like a black tree trunk or brown grass.
* The color pink or light green and white will tend to be called.
* Seeing red or green color is almost similar.
If you see signs like this, you should consult your pediatrician. Blind test of the most common color is Ishihara. Children will be shown a set of discs each with numbers or symbols hidden in the circle of dots. These symbols will be easily seen by normal vision, but not by those who seem color blind. By using this test, the doctor will know what kind of color blindness suffered by your child.
This condition will indeed affect your children. He may be a little frustrated, but will be able to adjust. It’s just that your child will find the problems as follows:
* Choosing a color crayon or marker
* Choosing a dress with matching color
* Reading a map or a color chart
* Not knowing when the meat has been cooked
* Lack of understanding signs traffic
* Must be a career that uses normal vision
You do not need to worry too much with this condition, because of course you can help your child in a color blind problem. Be sure to teach your child that color blindness is not an obstacle, but it is a unique trait. You can also separately adjust help themselves by:
* Accept your child color the call.
* Describing an object without mentioning the color.

* Expressing your child’s condition to the teacher.
* Talk with your child about his future that some jobs require a vision of a good color.
Until now I have found no drug that can cure color blind. But recently researchers at the University of Washington to do gene therapy for color blindness 2 monkeys in order to restore their vision of the color. This study gives hope that one day the drug from color blindness or other vision abnormalities can be found.
Ishihara Color Blind Test
Ishihara test is color blind test developed by Drs. Shinobu Ishihara. This test was first published in 1917 in Japan. Since then, these tests continue to be used throughout the world, until now.

Ishihara color blindness test consists of a sheet in which there are points with different colors and sizes. Colored points are arranged to form a circle. Color point was made so that the color blind people will not see the color differences are seen as normal people (pseudo-isochromaticism).
In normal people, in the circle would seem certain numbers or lines. But the color-blind people, who appeared on the circle will be different as seen by normal people.
Ishihara test is usually completed by an answer key for each share. The test results will be compared with one answer key. From here can be determined whether a person is normal or color blindness.
This test is usually done at the time we take care of able-bodied certificate.

Classification of Color Blindness
Color blindness is a condition when the retinal cells are not able to respond to color properly. Cone cells in the retina of the eye suffered permanent impairment or damage.
Classification of color blindness:
1. Trikromasi
Ie changing eye color sensitivity level of one or more cone cells in the retina. This type of color blindness is often experienced by the people. There are three classifications derived in trikomasi:
* Protanomali, a known weak color blindness red
* Deuteromali, green will be difficult to be recognized by patient
* Trinomali (low blue), the conditions under which the blue color are difficult to identify the patient.
2. Dikromasi
That is the situation when one of the three cones are not there. There are three derived Classifications:
Protanopia, red cones are not available so the brightness level of red color or a combination of his less
* Deuteranopia, the retina does not have cone cells that are sensitive to green
* Tritanopia, blue cones are not found.
3. Monokromasi
Monokromasi actually often regarded as people of color blindness by the public. This condition is marked with a damaged retina in response to the total color. Only black and white color that can receive the retina.
Causes of Color Blindness
Color blindness is a condition inherited genetically. Carried by the X chromosome in women, color blindness descended to his children. When someone is having color blind, their eyes are not able to produce the overall pigment required for normal eye function.
Eye Diseases Due to Lack of Vitamin
Vitamins are substances that the body’s metabolic needs, research found, that quite a lot of eye diseases are always closely connected with the lack of vitamins. Because vitamins can not with synthetic in the body or the lack of synthetic, so it should be necessary to absorb vitamins through food variety is very important for the prevention and treatment and reduce the symptoms of certain eye diseases. Then, eye diseases anything that would cause if the lack of vitamins?
1. Lack of vitamin A. Can cause disease night blindness, xerophthalmia and cornea softing. Manifestations are blurred vision in the light of a rather dim, dry eyes, easily tired and others. Because the physiological effects of vitamin A deficiency is associated with the visual impression of the dark, he could combine the name of a substance in the eye redopsin, redopsin have an important effect on the maintenance of the visibility adjustment is good and normal, associated with the maintenance of the integrity of skin structure and accelerate the development of growth. When immediately filled with egg yolk, milk, meat, pocai (like vegetables like spinach), tomatoes, carrots, chicory, fish, fish oil, animal liver and sebaginya., Can improve the symptoms mentioned above.
2. Lack of vitamin B1. Easy xerophthalmia arise, optic neuritis or orbital optic neuritis and others. Manifest dry eye, decreased vision, dilated pupil, slow to react to light, are interested in pain as the eye moves, the curve of her eye felt tight and sore and so on. Since the main physiological effects of vitamin B1 is to accelerate the process of cell metabolism, particularly related to the function of nerve conduction. Should be filled with foods rich in vitamin B1, such as feathers rice, wheat flour, foods from beans, animal liver, beans, pumpkin, bean sprouts, potatoes, apricot seeds, walnuts and so on. Very useful to reduce symptoms such as mentioned above.
3. Lack of vitamin B2. Most of the time can cause inflammation of the visual nerve, nodule eyes, inflammation of the lining eyes and so forth. Manifestations are decreased visibility, eye afraid of the light, tears flow, congestion, etc. cornea. If you frequently eat foods rich in vitamin B2, such as yeast, dairy foods result, beef, animal liver, soybeans, pocai, vegetable amaranth, ear mushrooms, sunflower seeds, and fruits and so forth. will be able to help prevent and treat the disease symptoms.
4. Lack of vitamin C. Can cause bleeding in the eyelids, anterior chamber, vitreous body, eye retina, and even can cause cataracts, and so on. Because the main benefit of vitamin C is to maintain the formation of substances between cells, following the oxidation of the cell structure and restore the original reaction to other metabolic reactions in the body, and has a softening effect of the blood vessels. Therefore, as vitamin deficiency, can cause bleeding of the eye, as mentioned above.
If you can eat more green vegetables and fresh fruits, will be useful to prevent bleeding in the whole body and the eyes. Because vitamin C can weaken the light and oxygen to the damage to the lens of the eye (the occurrence of disease associated with cataracts), so multiply that eating foods rich in vitamin C, may slow cataract disease.
