WHAT IS COLOR BLINDNESS?

It is a condition in which the ability to distinguish specific range of colors is average. A person suffering from color blindness has trouble seeing red, green, blue, or a combination.

A person's ability to see some combination of colors is rarely lost (monochromatic). Many people believe that only black and white colors are caught in a person suffering from Full(monochromatic) type. It has many different types and levels.

According to one of most popular survey, They will found 8% in men and only 0.5% in women.

HOW DOES THE COLOR BLIND TEST WORK?

He test is designed to evaluate a person's ability to perceive and differentiate between different colors. The most common type of color blindness is red-green color blindness, where a person has difficulty distinguishing between red and green hues. Other types, such as blue-yellow color blindness and total color blindness (achromatopsia).

One of the most famous color blind test is Ishihara Color Test, Designed by Dr Shinobu Ishihara. In this test, we used a series of plates, each containing a circle of coloured dots. Within these dots, numbers or shapes are hidden in a different color, which is hard to identify this color for the color-blind. People with normal color vision can easily identify these numbers or shapes, while those with color vision deficiencies may struggle to see them or see different numbers.

Identification of Numbers or Shapes: The plates are presented with different coloured dots in the form of any shape or number.

Color Vision Deficiency: A person with color vision deficiencies may have a problem noticing or identifying the hidden numbers or shapes due to the similarity in color between the background and the embedded figure.

Diagnosis: Based on the responses and the ability to identify the numbers or shapes, the test can provide information about the type and severity of color vision deficiency.

It's important to note that color blindness tests, including the Ishihara Color Test, are screening tools rather than diagnostic tools.

TYPES OF COLOR BLINDNESS & THEIR LEVELS

1. Red-Green Type

It is mostly seen in familial causes is damage or reduced red con or green con pigment function. There are four sub type of Red-Green Type.

Protanomaly - due to the unusual occurrence of red cone pigments. In this type, red, orange, and yellow appear green, and the colors are not bright. This condition is benign and usually does not affect daily life.

Protanopia - In this type, the red cone pigments stop working, and the red will appears as black. Some variants of orange, yellow and green all appear as yellow.

Some opticians prefer to use a reverse color blind test to diagnose colour vision deficiency. In this test, the patients are asked to identify the coloured object in the pallet within dynamic colored background.

Deuteranomaly - This is the most common type of found in peoples. It has an unusual green cone pigment. Yellow and green appear as red, purple and blue are difficult to identify. This condition is benign and usually does not affect daily life.

Deuteranopia - In this, green cone pigments stop working. They see red colors as brownish-yellow and green as dark yellow.

2. Blue-Yellow Type

Blue-yellow type is rarer than red-green. In this, the blue cone pigment (triton) is either absent or has a limited function. There are two types of blue-yellow type.

Tritanomaly - Blue cone pigments have less function. The blue color appears as green, and it cannot be easy to differentiate from pink to yellow and red.

Tritanopia - People with Tritanopia lack blue cone cells. Blue appears green in this, and the yellow color looks like purple or light brown.

3. Full (Monochromacy) Type

People with full type (Monochromacy) do not see any colors, and their clarity of vision can also be affected. There are two types of monochromacy

Cone monochromacy - In this, two or three cone cell pigments do not work. People with cone monochromacy have difficulty distinguishing between colors because the brain needs signals from different types of cones to see.

Rod Monochromacy - It is present from birth. It does not contain any of the available pigments of cone cells. People with rod monochromacy see the world in black, white, and gray.

DO YOU NEED TO PASS A COLOR VISION TEST FOR YOUR JOB OR LICENSING?

1. Pilot or Air Traffic Controller: Jobs in aviation often require individuals to pass a color vision test, as accurate color perception is important for interpreting aviation lights, signals, and other critical information.

2. Electrician: Some electrical work may require individuals to distinguish between different color-coded wires. Electricians may be required to pass a color vision test to ensure they can work safely and accurately.

3. Police Officer or Military Personnel: Certain roles in law enforcement or the military may require color vision testing, as it can be important for tasks such as identifying suspects or reading color-coded maps and signals.

4. Medical Professionals: Some medical professions may require color vision testing, particularly if accurate color perception is important for tasks such as interpreting diagnostic tests or distinguishing between subtle variations in color that may be indicative of health conditions.

5. Graphic Design and Printing: Professions that involve working with colors, such as graphic design or printing, may require individuals to have accurate color vision to ensure the quality and precision of their work.

It's essential to check the specific requirements for the job or licensing you are interested in to determine whether a color vision test is necessary.

LENSES, GLASSES AND COLOR FILTERS

Opticians supply colored specks lenses or single red-tinted contact lenses to improve vision related to some colors.

Studies show that issues in a cone cause wavelengths to overlap more, consequently leading to poor color vision.

The

glasses have tinted lenses that help individuals see colors more accurately.They use a filter to cut the overlapping wavelengths, allowing the user to give more precise color recognition.Glasses have many more useful daily life applications, like selecting clothes with perfect patterns of colors.

FREQUENTLY ASKED QUESTIONS

1. How Do I Check if I Am Color Blind?

To check for color blindness, take an online color vision test like the Ishihara test, which shows patterns of colored dots with numbers hidden inside. If you struggle to see the numbers, it could indicate color blindness. For a definitive diagnosis, consult an eye specialist.

There is no cure for genetic color blindness, but you can use special glasses and contact lenses that helps to see colors.
