What is Partial Color Blindness that Many People Experience

Rancakmedia.com - You need to know about what is partial color blindness that you need to be aware of because many people have experienced it.

Individuals who suffer from color blindness have difficulty distinguishing between different shades of colors or seeing colors as variations on a single color.

Therefore, there are several types of color blindness, one of which is partial or partial color blindness. Partial color blindness causes the patient to see blue as green or blue as green.

To find out more about partial color blindness, friends can listen to the following discussion. Come on, listen to add insight.

What is Partial Color Blindness

Rather than total color blindness, partial or partial color blindness is more common in some people. Most of the time, they are unable to see or cannot distinguish certain colors.

The molecule in the retina that is responsible for detecting color, the photopigment, malfunctions, and this is a possible source of the abnormality.

Thus, the condition of partial color blindness can be genetically inherited or exposed to toxic substances, as well as damage around the sense of sight.

Types of Partial Color Blindness

Generally, partial color blindness includes difficulty seeing red and green, therefore it is called red-green color blindness.

However, color blindness is further classified into four types, due to the limited number of cone (protan) and green (deutan) cone cells in the retina.

1. Protan Color Blind

Abnormalities in the red cone cells that function to perceive red color cause partial protan color blindness.

However, interference means that these red cone cells receive more green light than red light, which results in a color shift.

Therefore, people who have protan type partial color blindness, will see green, yellow orange, red, and brown as the same color.

Whereas purple looks like blue, pink looks like gray, and red looks like dark or black.

2. Deutan Color Blind

Deutan partial color blindness is an abnormality in the green cone cells which function to perceive the color green. However, due to interference, these green cone cells do not receive enough green light and instead receive more red light.

Because of their resemblance, people with partial color blindness have difficulty distinguishing between green, yellow, blue and purple. Meanwhile, green may appear bright or even white when viewed under certain lighting conditions.

They mistake pink for light purple.

3. Tritan Color Blind

Age-related macular degeneration, glaucoma and other eye diseases can all contribute to tritanomaly, which is a type of partial color blindness.

It can also be caused by yellowing of the crystalline lens inside the eye, as the cells don't repair themselves and are constantly exposed to UV radiation from the sun.

People who have tritan partial color blindness have a limited number of blue cone cells.

So, when it is damaged or reduced in function, it immediately impacts vision, because you can no longer see blue. In fact, it can be difficult to identify the difference between blue and green.

4. Monochromatic color blindness and achromatopsia

Partial color blindness is caused by diseases of rod cell monochromatism, cone cell monochromatism, and retinal achromatopsia.

Thus, patients may have normal trunks but no cones. So they can only see gray and black in all the colors they see.

Monochromatic partial color blindness is also affected by light sensitivity, photophobia (due to sensitivity to light in the eye), and the ability to see glare easily.

Conclusion

Rather than total color blindness, partial or partial color blindness is more common in some people. Most of the time, they are unable to see or cannot distinguish certain colors.

In the article above we not only discussed what partial color blindness is, but we also provide types of partial color blindness. If you want a partial color blind test, you can see partial color blind test link in the article we made before.

Thus the article about What is Partial Color Blindness that Many People Experience, I hope the article above can be useful and helpful for all of you,
