How the Red-Green Colorblind Tests works for Kids?

According to different research articles and study, it is observed that color blindness usually affects about 1 in every 25 kids.

The color blindness is often called color vision deficiency. This problem usually affects boys than girls.

A simple test can determine whether or not your kid suffers from color blindness.

How it occurs?

The color blindness is usually caused by a hereditary stipulation.

It means that children with color blindness are born with it, and this problem cannot be cured.

In this problem, the nerve cells located in the back of the eye (cones) are accountable for seeing and identifying different colors.

Usually, the children who suffer from color blindness lack cones.

In normal-sighted children, the cones establish to develop gradually at the age of 4 months.

Being colorblind does not inevitably mean you can’t see any colors or shades, though this is a widespread misconception.

There are different types of color blindness but by far the most common type is the incapability to differentiate between the colors of green and red.

Colorblind test

Most of the children are tested for color blindness at about 4 years of age as part of a vision analysis.

The doctor in this test simply asks the child to classify a red and green line.

If the child is unable to identify the colors correctly then more testing will be given.

In most of the cases, the child is given away different pictures that are composed of painted dots and lines.

If a child is unable to see a certain shape or picture or shape then there is a clear possibility that he/she is colorblind.

The Ishihara color sightlessness assessment is practically the most frequently used analysis to test color vision deficits.

Vision test is the perfect test for the diagnosis of colorblindness.

Complete the test at least once to find out whether you are colorblind or not.
