Why Is My Child Colorblind? (CVD)

What Is Color Blindness?

Color blindness known as color vision deficiency (CVD), is the decreased ability to see color or differences in color. For example, for some colorblind people, a dark red ball could be seen as brown, or any purple object could be seen as blue. It is extremely rare to see in black and white – it’s called Achromatopsia.

Color Blindness Affects:

8% of males and less than 1% of females are colorblind (4.5% of the whole population), which means there are more than 350 million colorblind people in the world.

In a class of 25, one, and possibly more students, likely will have difficulty distinguishing colors. Most will be male (Males are 17 times more likely to be colorblind than females).

4 Types of Color Blindness:


The green-weak (Deuteranomaly) and green-blind (Deuteranopia) colorblind have problems with any color that has some green in it.

Deutan color blindness is a type of red-green color blindness in which the green cones in the eye detect too much red light and not enough green light. As a result red, yellow, green, and brown can appear similar, especially in low light.


The red-weak (Protanomaly) and Red-blind (Protanopia) colorblind have problems whenever a color has some red in it.

A person with Protan type color blindness tends to see greens, yellows, oranges, reds, and browns as being more similar shades of color than normal, especially in low light.

A very common problem is that purple colors look more like blue.


The blue-weak (Tritanomaly) and blue-blind (Tritanopia) colorblind have problems seeing the color blue.


Rod monochromacy (RM), also called congenital complete achromatopsia or total color blindness, is a rare and extremely severe form of an autosomal recessively inherited retinal disorder resulting in a severe visual handicap. Rod monochromacy is a rare form of color deficiency, affecting only 1 in every 30,000 people).


What Causes Color Blindness?

Color blindness is inherited and is caused by a gene on the “X” chromosome. 2

A male (XY) has one X chromosomes, and always inherited from the mother, while a female (XX) has two X chromosomes, one from the father and one from the mother.

A male with one affected X chromosomes from his mother will be colorblind. A female with only one affected “X” chromosome will not have the condition but may pass the gene to one of her children.

A daughter can only be color blind when both her mother and father are color blind and pass along the gene. This is why color blindness affects more men than women.

Symptoms of Color Blindness

The symptoms of color blindness can range from mild to severe. Many people have such mild symptoms that they are unaware that they have a color deficiency. Parents may only notice a problem with a child when children begin to learn the different names of colors.

The symptoms of color blindness are:

  • Inability to tell the difference between shades of the same or similar colors. This happens most with red and green, or blue and yellow.

  • Seeing green and red as gray/brown.

  • Using the wrong colors when coloring an object – such as a purple river or red leaves.

  • Writing or drawing only with one color.

Is There A Treatment For Color Blindness?

To answer the question "Is there any cure for colorblindness?", yes there is, scientists, cured red-green color blindness in adult monkeys using gene therapy but currently, this method is not available for humans, and probably it will not be affordable for many in future. Read More

How Can Parents Help Colorblind Children?

In the past, there wasn’t much information about color blindness and most of the people with color deficiency either lived without knowing it or simply ignored this fact and had to find ways to cope with color-related challenges.

Students who are colorblind may:

● Have trouble with certain assignments or projects that require them to use color

● Can feel self-conscious or frustrated about their color blindness

● Be at risk for teasing or bullying because of color blindness

● Joining art classes, sports, and other extracurricular activities can be challenging

The proper role of the parent is to provide encouragement, support, and access to information that enables the child to master key developmental tasks. As a parent, it is your job to help your colorblind child develop the best strategies to cope with color-related situations and tasks. 4

If your child is colorblind, you need to learn more about his/her condition. If you don't take action now, in the future your child can face some challenges in communication, career opportunities, and self-confidence.

Are there currently any treatments for color blindness?

There are no preventative treatments as it's genetic. However colored filters, spectacles, and contact lenses have been introduced that can alter someone's color perception. They might allow the wearer to see a few more colors or colors nearer to how a person with normal color vision would see them, but it doesn't really solve the issue. Color blindness affects so many aspects of our life. You can learn some tips & tricks at this online training course designed for colorblind people.
