6. Take away
It is important to be positioned at a proper distance from the reading text. The ideal is 30 to 35 centimeters. If it is too difficult you can get a little more, avoiding it is not essential, the use of lenses.

7. Make eye gymnastics

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.
* Propose a selection clothes that are not in accordance withcaution.
* 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.

* Tritanopia, blue cones are not found.
