Ishihara’s boards are nothing more than characteristic colorful drawings made of colorful dots arranged in the shape of a circle. In the middle of each of them there is a digit, slightly distinguished by color and made of spots, and some of them also have lines. Each of the boards has a slightly different selection of colors, and in the original version there are 38 of them in total. However, usually after viewing a few of them you can determine whether there are color perception disorders.
Ishihara tables were created over 100 years ago. They were created by a Japanese ophthalmologist
this one is over 100 years old. It was created in 1917 by a Japanese ophthalmologist, Shinobu Ishihara, who worked at the Military Medical School. The boards he painted himself were intended to test recruits’ color recognition skills. Today, they are used not only by ophthalmologists during examinations, and their purpose is to check the ability to distinguish red and green colors. You can also perform the test yourself, although remember that it will not replace a proper diagnosis by a doctor.
What number do you see in the picture? Look carefully
Example? Look at the photo at the top of the page and think about what you see. The answer will help you find out if you have color vision impairment.
- 4: You have problems recognizing the color green – deuteranomaly, which manifests itself in a weaker perception of the saturation of green, which appears “washed out” and faded.
- 2: You have problems recognizing the color red – protanopia (not recognizing the color red) or protanomaly (red, orange or yellow colors appear faded and greenish).
- 42: You have no color vision disorders.
Emka, Huyen Pham, showed an even more difficult test on her YouTube channel some time ago. If you thought Ishihara boards were difficult, wait until you see this one.
Every 2 years, during periodic work examinations, 2-3 tables are shown to me and I have no problem reading the numbers. However, your test from level 5 gave me trouble.
1-5 all flawless, but the rest were really difficult.
I can’t see anything, but the most important thing is that I see the world in colors
