The presence and operation of light-sensing pigments in the cones of our eyes are essential for color vision.

When one or more of these cones malfunction, color blindness or color vision deficit results.

Protan color blindness is a kind of color blindness that develops when the eyes’ long wavelength-sensing pigments are absent or don’t work properly.

Protan color blindness makes it difficult for sufferers to distinguish between red and green.

This article will define protan color blindness and go into the diagnostic procedures and various therapies for people who have this particular form of color blindness.



Protan color blindness is a form of color vision impairment that develops when the eyes’ red-sensing pigments are either absent or broken.

The terms “protan color blindness” refers to both protanomaly and protanopia.

Red-green color blindness has two different degrees: protanopia is the more severe kind, and protanomaly is the milder.

✅ A color vision test can identify all types of color blindness, including protanomaly and protanopia.

✅ Even if protan color blindness has been identified in you, making minor adjustments to your daily schedule can still help you lead a full life.


What Is Protan Color Blindness?

It helps to study how the cones in the eyes produce color vision in order to comprehend what proton color blindness is. Certain chemicals, referred to as photopigments, are located inside the eye’s cones and are capable of sensing various light wavelengths.

S-cones (short wavelength cones), M-cones (medium wavelength cones), and L-cones (long wavelength cones) all perceive blue, green, and red, respectively. Protan color blindness is a kind of red-green color deficit that develops when the L-cones are damaged or absent.

Around the world, 8% of males and 0.5% of women suffer from red-green color blindness, with red-green color blindness being the most prevalent variety. Men are more likely to be affected than women because men are more likely to inherit the X-linked recessive gene that causes color blindness.

This is true because men only have one X chromosome, which means the disorder only needs one genetic alteration to manifest. However, since women have two X chromosomes, the disorder would require two genetic alterations to exist in them.


Protan color blindness types

There are various varieties of color blindness, and each type can have a different impact on a person’s ability to see colors. Red and green are typically difficult for the eyes to distinguish in protan color blindness.

Protanomaly and protanopia are the two varieties of protan color blindness.

  • When the L-cones are there but aren’t working properly, protanomaly occurs. As a result, red seems greener to the eyes.
  • Protanopia occurs when all of the L-cones are absent. The eyes have problems distinguishing between green and red without the L-cones.

Protan color blindness is one of the various types of color blindness, which can range in severity from mild to severe. Protanomaly, for instance, is less severe than protanopia and typically doesn’t present many issues in daily living.

Red and green are perceived quite differently as a result of protanopia, a more severe type of red-green color blindness.


Diagnostic tests

A color vision exam, often known as an Ishihara color test, measures how well one can see colors. Small colored dots can be found on each color plate. In the middle of the plate, a number or symbol is made up of some of these colored dots.

The number or symbol in the image will be visible and easy to recognize if you have a full-color vision.

However, you might not be able to read the number or symbol on some license plates at all if you don’t have a full-color vision. What you can and cannot see on the plates depends on what kind of color blindness you have.

There are a few significant businesses that specialize in offering free color vision tests online, even though the majority of eye doctors can perform color blindness testing.

On its website, EnChroma, one of the top manufacturers of technology for colorblind persons, offers a Color Blind Test. It takes less than 2 minutes to complete the test, which determines if you have mild, moderate, or severe color blindness.

You can also make an appointment for a color vision test with an eye care specialist if you believe you may be color blind and think it would be in your best interest to have a formal diagnosis.


Treatments available

The condition of proton color blindness is now incurable. To help them live better daily lives, there are businesses that develop devices for persons who are color blind.

For those who have color blindness, EnChroma glasses have been advertised as a technique to enhance color vibrancy and color differentiation. In a 2018 study, the efficiency of these glasses in enhancing participants’ color vision was assessed.

The EnChroma glasses did, in fact, somewhat alter the participants’ perception of the colors they could previously see, the researchers discovered. The glasses, however, were unable to enhance diagnostic procedures or return normal color vision.

Live with protan color blindness

Protan color blindness is common, and most sufferers lead normal lives. However, color blindness can make several daily activities more challenging, including using technology, driving, and cooking.

When you have color blindness, management strategies including memorizing, changing the illumination, and labeling systems can assist you get around in daily life.

Practice your memorization skills

Driving is one area where proton color blindness is very detrimental. Red is a common hue used in stoplights, stop signs, and other traffic signs and signals.

Even if you have color blindness, you can still drive safely if you can recall the layout and appearance of traffic signs and lights.

Label and arrange your clothing.

With protan color blindness, it might be challenging to choose certain outfit combinations, especially with red and green tones. Having a friend or family member sort and label items can be a tremendous benefit for persons with more severe color blindness.

When choosing clothing, you may then use the organization and labeling system to differentiate between various hues.

Improve your secondary senses

Four of our senses—taste, touch, hearing, and smell—help us get around in daily life. People with protan color blindness can nevertheless make use of all of these senses for daily activities, regardless of any underlying problems.

For chores like cooking food and selecting fresh vegetables, for instance, smell and taste can be useful even without full-color vision.

Ensure proper lighting

Insufficient lighting severely impairs our ability to see colors. Good lighting is advantageous for those who are partially color blind since it can make it easier for them to discern between the colors they can already see.

People who are color blind can benefit greatly from installing daylight bulbs and natural lighting in their homes and places of employment.

Utilize the accessible options

The majority of electronic devices, including phones, TVs, and laptops, provide accessibility features for those who are color blind. To make using these devices easier, these choices can help modify specific screen colors.

Additionally, there are several apps available that might assist those who are colorblind in identifying colors that they might not be able to see.
