Color Blind Test

Check if you have a color vision deficiency by taking our free online test. Learn more about color blindness, their treatments and which type of do you have.

We use below tools or tests to check color vision deficiency. Each test have different strategy to detect issues with your color vision.

BEFORE START TEST

The test consist of various colored ishihara plates on which multiple digits are printed, You just have to recognize the digits correctly to pass the test. To get correct result, please take care of the following things BEFORE starting the test:

  • Remove any glasses with colored lenses if you wore right now. The test is only designed to be taken with the naked eye, and it will work only without colored lenses of any type and lead to accurate results. Taking the online test with color-correcting glasses to “prove” that they work is a misconception and inaccurate.
  • Increase your screen brightness too high. Dim light affects color & the ability to perceive differentiation.

What is Color Blindness?

It is a condition in which the ability to distinguish specific range of colors is average. A person suffering from color blindness has trouble seeing red, green, blue, or a combination.

A person's ability to see some combination of colors is rarely lost (monochromacy). Many people believe that only black and white colors are caught in a person suffering from Full(monochromacy) type. It has many different types and levels.

According to one of most popular survey, They will found 8% in men and only 0.5% in women.

Types of Color Blindness & Their Levels

1. Red-Green Type

It is mostly seen in familial causes is damage or reduced red con or green con pigment function. There are four sub type of Red-Green Type

  • Protanomaly - due to the unusual occurrence of red cone pigments. In this type, red, orange, and yellow appear green, and the colors are not bright. This condition is benign and usually does not affect daily life.

  • Protanopia - In this type, the red cone pigments stop working, and the red will appears as black. Some variants of orange, yellow and green all appear as yellow.

  • Deuteranomaly - This is the most common type of found in peoples. It has an unusual green cone pigment. Yellow and green appear as red, purple and blue are difficult to identify. This condition is benign and usually does not affect daily life.

  • Deuteranopia - In this, green cone pigments stop working. They see red colors as brownish-yellow and green as dark yellow.

2. Blue-Yellow Type

Blue-yellow type is rarer than red-green. In this, the blue cone pigment (triton) is either absent or has a limited function. There are two types of blue-yellow type.

  • Tritanomaly - Blue cone pigments have less function. The blue color appears as green, and it cannot be easy to differentiate from pink to yellow and red.

  • Tritanopia - People with Tritanopia lack blue cone cells. Blue appears green in this, and the yellow color looks like purple or light brown.

3. Full (Monochromacy) Type

People with full type (monochromacy) do not see any colors, and their clarity of vision can also be affected. There are two types of monochromacy

  • Cone monochromacy - In this, two or three cone cell pigments do not work. People with cone monochromacy have difficulty distinguishing between colors because the brain needs signals from different types of cones to see. This comparison is not possible when only one type of cone works.

  • Rod Monochromacy - It is present from birth. It does not contain any of the available pigments of cone cells. People with rod monochromacy see the world in black, white, and gray. People with rod monochromacy are photophobic and very uncomfortable in bright environments.

How to Test Color Blindness?

There are many tests available to check color vision deficiency, But Ishihara test is a standard method. This will test red-green type. It is most likely used for regular color vision in government jobs, schools or medicals.

The Ishihara test includes 38 circular plates having printed digits on which are created by unique random dots in more than one color. The plate will be shown in the test to the person and asked which number will be seen.

If a person makes some mistakes during the test, they are diagnosed with color blindness.

Lenses, Glasses and Color Filters

Opticians supply colored specks lenses or single red-tinted contact lenses to improve vision related to some colors.

The studies show that issues in a cone cause wavelengths to overlap more, consequently leading to poor color vision.

The glasses have tinted lenses that help and give the ability to the person to see more colors accurately.

The glasses use a filter to cut the overlapping wavelengths, allowing the user to give more precise recognition between colors.

Glasses have many more useful daily life applications, like selecting clothes with perfect patterns of colors. It also helps a person to grow in their color-related profession, such as graphic designing and working profiles that require handling various electrical wiring having lots of colors depend on correct color perception.

Frequently Asked Questions

Try our free online test for an initial check. It can be done at home by online medium from your pc, laptop, or mobile devices. We have various tests to determine whether you are color blind. Before starting this test, you need to read all instructions, look carefully at a series of Ishihara plates, and then answer some simple questions about what you see in those images. After ending the test, the results will show you whether or not you have color blindness, which is the inability to see color differences in a specific range. Suppose it shows that you failed the test and have symptoms of it. In that case, it is necessary to consult your nearby doctor or optometrist to find out what specific conditions may be causing this condition and discuss Treatment options. Ultimately, taking care of your eyes by identifying any vision problems early can help ensure optimal functioning.

There are four main types: Red-Green, Blue-Yellow, and Full (Monochromacy). Each color vision deficiency results from specific eye defects or abnormalities that affect how an individual sees color. For example, individuals with the Red-Green type are less sensitive to color variations in the spectrum's red and green regions. Individuals with the Blue-Yellow type may not distinguish between hues such as cyan or blue-yellow. And people with Full (Monochromacy) Type have difficulty seeing any color.

Driving is a most difficult skill, allowing people to navigate the roads safely and access work, school, and other destinations. However, not everyone has this ability. Some people suffer from color blindness, making it difficult to differentiate some colors and combinations. Many have wondered whether color-blind drivers are safe to drive on the road, but this question depends on their particular type of color blindness. For instance, color blindness can be detected with a simple online test. Regardless of the cause, all color blind drivers can benefit from taking extra care behind the wheel and being especially careful by consulting to doctor and taking Treatment like glasses or lenses while driving.

It is estimated that it affects roughly 10% of the population, with different severity levels. Most color-blind individuals are considered to have what is known as partial color blindness, meaning they experience some difficulty distinguishing colors but remain able to see color in most situations. However, some people possess complete color vision deficiency, meaning they cannot see colors at all and see the world only in shades of grey.

There are several different types, but the most common type is caused by an altered or absent color of Photopsin pigment in the eyes. It will also be caused by other conditions that affect the eyes, such as cataracts or macular degeneration. Most of all, it is hereditary but can also be acquired through illness or injury.

It is relatively common, affecting up to 8% of men and 0.5% of women worldwide. While it is not a severe condition, it can impact a person's ability to participate in certain activities, such as driving or identifying colors in a work environment. There are several ways to adapt to color-blindness, including color filters and special glasses by consulting a doctor.
