Color blindness is usually diagnosed in children aged 3-4 years, when the child development standards should clearly distinguish between the primary colors. If the family is one of the parents suffers from some form of color blindness - it is an occasion to strengthen the monitoring of the behavior of the child.
Pay close attention to how the kid draws. If he makes a mistake when choosing a colored pencil, because in a hurry, and passionate about the process, and at the first accent on it ( "Is it a weed you see on the street?"), then corrects their mistake and draws the green herbs - is one thing. But if in his drawings appear regularly not red poppies and gray, not yellow sun and brown - surely there is something wrong with the color perception.
If you are "plagued by vague doubts", perform a simple experiment. Take 2 equal favorite goodies kid (candy, cake, apple, but it is imperative that he has seen them!) And wrap each in colored paper. One - in red paper, and another - in black (brown or any other, but unattractive in appearance). After that, have a child choose a treat anytime. If the child is healthy, he is psychologically always pulled everything bright and chooses what in a red wrapper. But if he does not distinguish the colors, then it takes any (possibly - black), because they are all the same for him.
For the "purity of the experiment," it must be repeated several days, 2-3 times a day, recording the result. If a couple of times a child made a mistake, it could be an accident, but if it is repeated constantly - is a trend. What to do in this case? Be sure to make an appointment to the ophthalmologist.
If the child is 5-6 years old and has developed normally for his age, the breach of color it can be identified with the help of special tables Rabkin (medical test for color blindness). These are figures made by means of dots or circles of equal brightness that are different in color. As a rule, noting the degree of brightness, color, color-blind people do not notice. Therefore, at some tables, they will not see a faint image by taking the table just as a uniformly filled circles the field.
If the diagnosis of "color-blindness" officially put, it means to the boy that he is likely in the future will not receive permission to drive a car, can not serve in the army, worked as a chemist, and a pastry etc.
