Color Deficiency? why can’t I differentiate?

Color blindness isn’t quite what it seems. Most persons with the disease can distinguish some colors but not others. “Color deficiency” might be a more appropriate moniker. Whatever you choose to name it, it affects more males than women. Colorblindness affects roughly 1 in 12 males and 1 in 200 women.

There are two types.

You can’t detect the difference between some shades of red and green if you have the most prevalent type of color blindness. Others have a personality that causes you to mix up blue and yellow colours. It can be mild, moderate, or severe in either case.

How you see colors

Your retina is a light-sensitive layer in the back of your eyeball. Rods and cones are the two types of cells found in it. The cones react to brighter light, whereas the rods work in dim light. Colors have an effect on both of them. Their signals travel through your optic nerve to your brain, where they are mixed to create the rainbow’s colors. About 12% of women have a special type of cone that allows them to see 100 times more colors than men.

How color blindness happens

Colorblindness indicates that you have a problem with at least one type of cone. Those cones could be missing, or they could be the wrong color. Some cones, for example, may contain faulty genteic coding for color-sensitive compounds. They can’t deliver the proper information to your brain either way. Colorblindness may cause you to see a little less sharply because the cones also help you see the minute details of what you’re looking at.

Why it happens: GENES

Colorblindness is a condition that most people are born with. This is due to the fact that it usually starts with the genes you inherit from your parents. Those genes don’t provide your body with the information it needs to generate blue, red, and green pigments for your cones. The cones are unable to detect colors without pigments.

Why it happens: DISEASE

Some people who aren’t born with colorblindness can be affected. It can be caused by some eye disorders, such as galucoma, as well as leukemia, Parkinson’s disease, Alzheimer’s disease, sickle cell anemia, or an alcohol use disorder.


Colorblindness is a side effect of various medicines, including those used to treat heart disease, high blood pressure, erectile dysfunction, nervous system diseases, and psychiatric disorders. Working with chemicals such as fertilizers or solvents can also cause colorblindness. Secondary color deficiency can be caused by things like taking certain drugs or working with specific chemicals, although it is extremely rare.

How it’s found

You may not realize your child is colorblind until they begin to learn the names of colors. Alternatively, they can struggle in school with color-coded examinations or homework. Around the age of four, it’s a good idea to test your child’s color vision. If you have a family history of colorblindness, have your child examined by an eye doctor.

How it is diagnosed

The Ishihara color test is the most common approach to determine whether or not someone is colorblind. It makes use of images of dots in a variety of hues. You’ll see a number or another shape in each image if you perceive color correctly. You won’t be able to if you’re colorblind. You can purchase the test and perform it on yourself, but an eye doctor will be able to do a better job.

Living with it: GADGETS

Color-matching apps for your smartphone or tablet computer can help you figure out what color something is. You take a photo, and the app shows you the hue when you tap on a spot in the image. Some apps can even distinguish between different color tones. Special eyeglasses may help you see colors more clearly if you have red-green colorblindness.

Living with it: HABITS

If you’re colorblind, having someone help you put labels on your clothes that tell you what color they are will help you pick items that match. Arrange your clothing in your closet such that they are close to one another. You might also memorize the color order of numerous items, such as traffic lights.


You might be able to do anything about your colorblindness if it was caused by a sickness or is a side effect of prescription medications. Your doctor, for example, may be able to prescribe an alternative medication. However, the most common type of colorblindness, which you inherit from your parents, is incurable.

Researchers are exploring for ways to improve the function of the cones in order to alleviate colorblindness caused by genetics. Animal experiments have been promising, and clinical trials, or human trials, are currently underway.
