THE BEST WAY TO PASS A COLOR BLIND TEST

How To Pass Color Blind Test

COLOR BLIND TEST: WHAT ARE THEY? 

The color blind test is a test to different between color blindness and determine the type of color blindness. 

Generally, it includes color naming test , matching test , confusion test , and laboratory tests . 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’s improved color blindness test was determined as a must-have tool for a color blind test at the 13th International Ophthalmological Society Conference in 1929.

WHY DO I FAIL IN THE COLOR BLIND TEST?

 There are four types of color vision deficiency . If you have one of them, you’ll not pass the test.

1.  DEUTERANOPY

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.

2. DEUTERANOMALY

Deuteranomaly weak green.  Red and green are more common . They have poor sensitivity to red and green. When the lighting is poor, their color discrimination ability is close to red-green blindness; but when the material color is deep and bright and the illumination is good, their color discrimination ability is close to normal.

3. PROTANOPIA

Protanopia is also known as the No 1 color 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.

4. PROTANOMALY

Protanomaly  Red weakness , red looks greener and less bright.

About 99% of all color blind people are red-green color blind. over 8% of men and 0.5% of men have it.

WHAT DOES A COLOR BLIND PERSON SEE?

1. By using the Ishihara color blind test plate normal vision people and color blind people see different results, so they got the wrong answer.

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 color blindness test. 

According to the experiments of scientists at the University of Houston in the United States, under the stimulation of strong light for a long time, the optic nerve of human glasses will be fatigued, and it is easy to fail to pass the color blind test.

So generally do not use your eyes for a long time before the test, such as playing tv games 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), which treats tuberculosis, may cause optic nerve problems and difficulty seeing some colors.

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

Long-term exposure to organic solvents such as styrene, carbon disulfide, perchloroethylene, n-hexane, and solvent mixtures, as well as organic and inorganic mercury, can have significant effects on color perception. 

For some of these compounds, by finding a clear dose-response relationship, Further identified effects on color vision, such as hours of exposure to toluene or acute alcohol ingestion, appear to affect color perception.

HOW TO CHEAT A COLOR BLIND TEST

If you’re color blind and have to take an exam, you might be worried that it will be difficult or impossible for you to pass. 

You may have heard that there are many ways for people with normal vision to cheat on tests and wondered if there were any ways for a person with color blindness to cheat on their tests. 

Well, the truth is that several strategies can help you pass even if you’re color blind!

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 at a time as opposed to taking in everything at once (and seeing nothing).

  • Look through a cellophane film to see the numbers on the test. This involves placing a piece of cellophane over top of each box before filling it out with ink or pencil marks; once you’ve finished all these steps, remove them from underneath your glass/mirror surface until you’re ready for someone else’s turn! 

Cellophane film comes in rolls that cost about $2 a piece; if necessary, buy several different colors so we’ll know what color vision deficiency our friend has been suffering from all this time.

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 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 get fancy with it and 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 allow for greater detail when distinguishing between different colored numbers like 0 versus 9 or 4 versus 5—so if this is something that stands out for you as particularly difficult, this might be worth trying!

Use a friend or family member who is not color 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 colors.
  • Try practicing with them before the test.

PEOPLE WHO NEED TO PASS COLOR BLIND TEST

Color blindness brings a lot of inconvenience to our work and life, so in daily affairs and work that require color distinction, we must take the impact of color blindness seriously.

People who work in the below career should pass the color blind test

  • The color and reaction of reagents and solvents must be correctly identified in chemical experiments and chemical production;
  • In the textile, printing, and dyeing industry, color selection must be carried out;
  • Metallurgy and foundry industry. The temperature of the molten metal needs to be judged by its color;
  • Color blind people are wrong in color discrimination and should not be engaged in these occupations.
  • Aircraft, ships, trains, car drivers, and traffic managers. Various color signals must be distinguished correctly. If a wrong judgment is made, it may lead to serious accidents.
  • If you are a student, the color blind cannot apply for majors in most countries

WHAT CAN I DO TO IMPROVE MY COLOR VISION?

COLORBLINDNESS IS INCURABLE BUT CAN BE CORRECTED

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

In many cases, color vision deficiency may not be severe enough to warrant any treatment. If you are concerned about your color vision deficiency, speak with your eye doctor who can test your ability to distinguish between different colors and hues.

1. For people with normal vision, be careful not to over-stimulate and fatigue your eyes for a long time.

Limiting the use of mobile phones, controlling the time watching TV, playing games, the stimulation of alcohol in nightclubs, and the stimulation of sound and light can cause extreme eye fatigue.

2. For people who have color vision deficiency  wearing color blind glasses by Enchroma can solve various color distinction problems caused by color blindness in life.
