Test Color Vision Defects With This App
What is color blindness?
This is a condition that prevents you from being able to differentiate between some colors.
When a person suffering from this condition sees colors, the perception is not accurate because the differences between them are not sufficient enough for the person to distinguish them.
When a person suffering from this is asked to determine which color is darker or lighter, they will be unable to answer accurately.
In addition, color blindness can lead to confusion, loss of concentration, and difficulty in solving mathematical problems.
There are many ways to detect color blindness, and the most popular and well-known is the Ishihara test.
What is the Ishihara test?
The Ishihara test is used to determine the existence of color blindness and to screen for defects. This test consists of 38 circles.
The task is to find the number that corresponds to a specific circle. The test is performed with the use of plates with numbers and colors.
The results of the Ishihara test indicate a deficiency in red-green color perception. It is recommended to perform this test as a screening method in order to detect color blindness in a person.
