Color Blind Test

Try our mostly recommended color blind test to check your color vision deficiency and know if you're a color blind person.

INSTRUCTIONS FOR COLOR BLIND TEST
  • This test shows you various types of Ishihara plates, each displaying numbers with multiple color possibilities you must identify to pass this test correctly.
  • Remove any glasses with colored lenses. This test requires you to use your naked eye; for proper results, you can use your daily glasses for your eyes.
  • Increase your device screen brightness to a high level for better visibility. Dim lighting can affect your ability to see colors correctly.
  • For better-optimized test results, take this test on a larger screen, like a tablet/laptop.

WHAT IS COLOR BLINDNESS?

Color blindness is a vision condition where the user has difficulty differentiating colors. It occurs when the eye color cells are missing or not working precisely. The most common type affects red and green shades, making them hard to distinguish.

Common types involve difficulty recognizing between blue and yellow or seeing in only shades of gray. Color blindness is hereditary but develops due to diseases of the eyes, increasing age, or any damage to the eyes.

HOW DOES THE COLOR BLIND TEST WORK?

A color blind test evaluates how well a person can distinguish between colors. The most common test is the Ishihara test, which uses a series of Ishihara plates filled with different colors of dots and sizes. Each Ishihara plate contains a number or pattern that a color-blind person may have a problem seeing or may see differently than those with normal color vision.

Before starting the color blind test, read the instructions carefully. To start the test, you just need to click on the PROCEED button. After starting the test, the test window will open to the user, and you will see Ishihara plates in the left corner and a number pad in the right corner.

To perform a color blind test, you need to recognize the number from that image and click that number on the num pad to submit your answer. Just follow this process until the test shows the result at the end of the test.

In the report, the test will show which type of color blindness you have and other related descriptions. The correct and wrong submissions are also displayed in the test results so you can identify which plate you missed and the wrong input you submitted.

TYPES OF COLOR BLINDNESS & THEIR LEVELS

Color blindness is categorized into three major types are as following:

1. Red-Green Color Blindness Type (Mostly Common)

  • Protanomaly - The red color appears more faded, like brown or grey color.
  • Protanopia: The red color looks like black or dark grey, and orange, yellow, and green appear similar.
  • Deuteranomaly (Mild) - The green color seems to be faded or more like yellow.
  • Deuteranopia (Severe) - The green color and red look similar, making it hard to distinguish between them.

2. Blue-Yellow Color Blindness (Rare)

  • Tritanomaly - (Mild) - The blue color appears greenish, and it's hard to distinguish yellow from red and pink.
  • Tritanopia - (Severe) - The blue color looks green, and yellow seems light grey or violet.

3. Complete Color Blindness (Very Rare)

  • Cone Monochromacy (Severe) - One of the three types of cones (red, green, or blue) is missing or non-functional, leading to poor color perception and vision issues.
  • Rod Monochromacy (Achromatopsia - Most Severe) - No functioning cones, meaning the person sees only in shades of grey. They may also experience light sensitivity and poor visual clarity.

WHAT ARE THE USES OF A COLOUR-BLIND TEST?

A color blind test is used for various purposes, as follows:

Career Screening

There are various career fields where this test is required, for example, shown below:

  • Air Traffic Controllers - It will used in aviation industries.
  • Electricians and Technicians - Where colored wiring is necessary, a colorblind test is required to ensure proper wiring in the field.
  • Graphic Designers - We all know how important colors are in graphic design, so users must know the perfect colors.
  • Defense - In defense the colors have much more importance for quick action in the training or in war so user must not color blind in the defense.
  • Healthcare Professionals

Driving and Traffic Safety

  • It's essential to know that the signal light color is accurate and who will drive the vehicle for safety concerns.
  • In many countries, the color blind test is required to get a driving license for better driving.

Scientific Research and Genetic Studies

  • By taking color blind test on a color blind person, science will study color blind people's genetics to understand hereditary color vision deficiencies and cures for them.
  • It helps researchers study eye disorders and develop new treatments.

LENSES, GLASSES AND COLOR FILTERS

People with color blindness deficiency can use specialized lenses, glasses, and other things to enhance color vision. To help individuals differentiate colors more effectively in daily life.

1. Color Blind Glasses

  • Use special tinted lenses to enhance contrast between colors.
  • Block specific wavelengths of light to improve color differentiation.
  • Designed for red-green color blindness (Protan and Deutan types).

2. Color Blind Contact Lenses

  • Similar to glasses but in contact lens form.
  • Have a special tint to adjust how light enters the eye.
  • Provide a more natural look without wearing glasses.

3. Color Filters (Digital & Physical)

  • Physical Filters: Special clip-on filters for glasses that enhance contrast.
  • Digital Filters: Software or apps that modify screen colors for better visibility.
