Color blindness tests confirm the presence of this change in vision, as well as helping your doctor identify the type, which ultimately facilitates treatment. Although the color test can be done online, the diagnosis of color blindness must be confirmed by an optometrist.
Identifying color blindness in childhood is important to make your child feel more integrated into the classroom, thus increasing academic performance. In the case of adults, knowing their own type of color blindness allows to adopt strategies to know how to combine colors in clothing or decoration, or differentiate between green and red apples, for example.
To better understand what color blindness is and what types exist
There are three main tests that can be used to help diagnose color blindness. Include:
One of the easiest tests at home to try to identify a case of color blindness is the Ishihara test. To do this, you should look at the following image:
What should be noted in the images is
Although this test may indicate the risk of color blindness, it is not used to make the diagnosis and therefore an optometrist should always be consulted.
The children’s Ishihara test is to observe geometric shapes and paths, because children do not always know the numbers, although they can see them.
Then, to test with the child, you should ask him or her to observe the following images for about 5 seconds and try to follow the paths presented with your finger.
When the child cannot relate what he sees, nor follow the forms on the image, he or she may indicate a case of color blindness and therefore it is advisable to consult a pediatrician and an optometrist.
In addition to these tests, your doctor may also use other methods, such as electroretinography, for example, to evaluate the eye’s electrical response to luminous stimuli.
Milder cases of color blindness in most cases may become undiagnosed, as the person does not experience many changes in their daily life and therefore does not seek medical help either.
Usually, from the age of 3 it is suspected that the child is color blind when he is not able to correctly identify the colors, but usually his diagnosis is done later, when he already collaborates better with the test, he better identifies the numbers. and test numbers.
It is possible to start distrusting the diagnosis when the child cannot respond correctly when asked about a color or drawings painted in incorrect colors, such as painting a pink carrot or yellow tomato, for example.
In addition, another common sign of color blindness occurs in adolescence when the young person is unable to coordinate colors correctly. For example, it is recommended that the ophthalmologist be consulted before the child enters school, to perform appropriate vision tests and diagnose any problems in addition to color blindness.
