Have you wondered what it is like to see beyond the muted tones of color?

What is color blindness?

Color blindness is another term for color vision deficiency. This is a medical condition in which people have difficulty distinguishing between certain colors. Color blindness has affected a million people worldwide. This vision deficiency alters how we perceive certain colors.

It is like red appears to be green, green appears to be gray, and the entire rainbow feels faded. But wait, there is a free and easy-to-use color vision test that is your secret portal to a vibrant world.

It is generally caused by some issues with the cone cells in the retina. Cone cells are majorly responsible for color vision, and there are three types of cone cells: red, green, and blue. Color blindness could be inherited or acquired. Inherited means it is passed down from parents to children through gene mutation. Acquired color blindness is caused by several factors, such as eye diseases, medications, and injuries.

If you also think that you might have color blindness, worry not, because you can see an eye doctor who can help you cope with your condition. Here in the article, we will guide you through a series of patterns and dots so that you can reveal the ultimate secret to color perception.

What are the types of color blindness?

Color blindness is usually responsible for hindering color vision. As mentioned earlier, the problem in the cone cells in the retina causes color blindness. Basically, there are three different types of cone cells, including red, green, and blue. If one or more of these cone cells are missing or not working properly, it can lead to a loss of color vision.

Here is a brief description of

1. Red-green color blindness

Among the three different types of color blindness, red-green color blindness is the most common. Here, it becomes difficult to differentiate between red and green colors. Also, people are unable to see the shades of such colors. The major three subtypes of red-green color blindness include:

2. Protanopia

There are no functional red cones, which leads to a lack of red sensitivity. Red could appear brown or orange. Also, green could appear like a brown or gray color.

3. Deuteranopia

If you have deuteranopia, you might see green, muted, brownish, or yellowish. This is because there are no functional green cones, which ultimately affects the green sensitivity. Moreover, red can appear orange or brownish. Also, check these warning signs of eye disease. 

4. Anomalous Trichromacy

Protanomaly and deuteronomaly are the milder forms of red-green color blindness where there is reduced cone function. Here, the color confusion is less severe, but distinguishing between certain shades can be challenging.

In anomalous trichromacy, people possess all three types of cones; however, one of the cones doesn’t have any normal spectral sensitivity in comparison to the normal cones.

5. Blue-yellow color blindness

This is a less common type of color blindness, where there is difficulty seeing blue and yellow. Moreover, people become unable to see the shades of blue and yellow.

The primary subtype of blue-yellow color blindness is tritanopia, where one generally lacks blue cones. This impacts blue and yellow sensitivity. If you have tritanopia, the blue appears to be greenish or grayish, and the yellow color appears to be orange or brownish.

6. Complete color blindness

Complete color blindness is one of the rarest forms of blindness. Here, one can only see gray and other shades of gray. Another umbrella term for the varying degree of severity of complete color blindness is achromatopsia.

On a rod monochrome, only the rod cells function, which will provide only black, white, and grey shades. There is no other perception of other particular colors.

However, in cone monochromacy, one type of cone remains, which eventually enables limited color perception, such as blue, yellow, or red.

Reclaiming your Color Vision with the Free Color Vision test

Wondering if you also have any issues with your vision or are planning to go to an ophthalmologist? Not anymore, because the color vision test will help you get your color vision diagnosed at home for free.

A color vision test is an assessment that will evaluate your ability to distinguish between different colors. While there are different types of color vision tests, the free online test will focus on the common types of color vision deficiency.

There are mostly three types of color vision tests.

1. Ishihara plates

This test consists of dotted circles with numbers or shapes formed by different colored dots. This is the most common online test method. People usually affected by color vision deficiency can take this test. They may struggle to see the number or shape that is incorporated into the figure.

2. Lantern test

This test uses colored lights and filters to assess color perception. Initially, different subjects with pairs and sequences of colored lights are presented to you for a brief period. Thereafter, you will be asked to identify the colors, which will reveal if you could have any potential confusion between any hues of color due to color vision diseases. For example, while identifying a green light, a pair of red and green lights is shown rapidly

3. Color matching tests

In this test, you will be presented with a subject with a colored reference sample and will be required to choose from such different colored samples that one that will perfectly match the reference. A subtle difference in color perception arises due to color vision disease. Make a choice for vibrant hues.
