How To Pass Colour Blindness Test

color blind test

The color blindness test is a test to differentiate between color blindness and to determine the type of color blindness. Generally, it includes color naming test, matching test, confusion test and laboratory test. The color naming test is the simplest. The test requires the examinee to name the color.

Sterling designed the color blind test in 1889. Ishihara improved the test. It was called a must-have tool for color blind tests. This happened at the 13th International Ophthalmological Society Conference in 1929.

WHY DO I FAIL IN COLOR BLIND TEST

Deuteranopia

Deuteranopia is the most serious form of red-green color blindness.

It cannot perceive green. The patient cannot distinguish between light green and dark red, purple and cyan, magenta and gray, and treats green as gray or dark black.

Deuteranomaly

Deuteranomaly weak green. Red and green are more common. They have poor sensitivity to red and green. In poor lighting, they are nearly red-green blind. But, in good light and with deep, bright material, their color vision is close to normal.

Protanopia

Protanopia is also known as the No 1 colour blindness. The patient mainly cannot distinguish red, and cannot distinguish red from dark green, purplish red, and purple. Green is often regarded as yellow, purple is regarded as blue, and yellow and blue are mixed into white. There was a middle-aged man with a mature and serious attitude who bought a red woolen sweater and ridiculed it after putting it on.

Protanomaly

2.Do not participate in strenuous activities before the test, which can easily fatigue your eyes.

This also makes it impossible to pick the correct answer in the colorblindness test. Scientists at the University of Houston in the United States did the experiments. They found that, with strong light for a long time, the optic nerve of human eyes gets tired. Then, they easily fail the color blindness test.

So generally do not using eyes for a long time before the test, such as playing tv game all night, mobile phone, etc.

Especially in the nightclub, the light is very dazzling. In this environment for a long time, the stimulation to the glasses will be very strong.

3.Certain drugs can cause changes in color vision. These include the antipsychotic medications chlorpromazine and thioridazine.

The antibiotic ethambutol (Myambutol) treats tuberculosis. But, it may cause optic nerve problems and trouble seeing some colors.

4. Chemical exposures will let you not pass the test.

Exposure to organic solvents, like styrene, carbon disulfide, perchloroethylene, and n-hexane, and to solvent mixtures, and to organic and inorganic mercury, can greatly harm color vision. This harm comes from long-term exposure.

For some of these compounds, we found a clear dose-response relationship. We also found other effects on color vision, such as hours of exposure to toluene or acute alcohol ingestion. These effects appear to affect color perception.

You can blur your vision or look through a cellophane film to see the numbers.

  • Blur your vision by rubbing your eyes. This can be done by closing one eye, then the other, and then blinking rapidly. The idea is to blur the letters on the test so they look like they’re moving around. When you press your fingers against a wall or something else solid, it will help you focus on one part of the test. This is instead of taking in everything at once and seeing nothing.

  • Look through a cellophane film to see the numbers on the test. This involves placing cellophane on each box before filling it with ink or pencil marks. Once you’ve finished, remove them from under your glass or mirror until it’s someone else’s turn! Cellophane film comes in rolls that cost about $2 each. If needed, buy several colors. We want to know what colors our friend can’t see.

You can magnify the screen with your phone camera and then use the screen as a viewfinder

You can magnify the screen with your phone camera and then use the screen as a viewfinder (so you’re not actually looking at the picture). This method does require some training, but it is possible.

Isolate the numbers. You can do this by zooming in/brightening them on your phone or using other optical tricks.

If you’re taking the test on a computer, zoom in and brighten the screen. If you’re taking the test on paper, use a magnifying glass to enlarge and lighten the number. If you don’t have one handy, try making one out of folded paper or a lens from an old pair of glasses.

If you want to cheat at home (or in front of your friends), you can also take pictures of each number using your phone camera app or any other camera. The more zoomed-in images will show more detail. They will help when distinguishing between different colored numbers like 0 versus 9 or 4 versus 5. So, if this is a particularly hard part for you, it might be worth trying!

Use a friend or family member who is not colour blind to tell you the numbers.

  • Use a friend or family member who is not color blind to tell you the numbers.

  • Ask them to help identify the colours.

  • Try practicing with them before the test.

Color blindness can be treated with various types of glasses, contact lenses or surgery.
