Factors Causing Color Blindness

Our eyes have special nerve cells that contain pigments that react to color and light. These nerve cells contain pigments that react to certain color colors. The damage that occurs to the cell or the malfunction of this pigment causes certain colors to be detected by the eye.

Damage that occurs in cells due to gene abnormalities that decrease from parents to children. Besides being due to gene weakness there are also several other factors that cause cell damage, including:
• Diabetes, glaucoma, or multiple sclerosis
• Drug side effects of digoxin, ethambutol, phenytoin, chloroquine and sildenafil
• Exposure to carbon disulfide and styrene chemicals
• Injury to the eye due to an accident.

Age is also a factor that causes a person to experience color blindness. Along with increasing age, there is a decrease in the ability of the eye to capture light and color. This is a natural process that can happen to everyone.

Color Blind Symptoms and Types

Color blindness is a condition where the sufferer has difficulty distinguishing certain colors or even the overall color. Symptoms that are felt by each patient can be different, depending on which pigment cells are damaged or not functioning.

Symptoms of color blindness are basically divided into three types, namely red-green, yellow blue, and total. Each type has a different symptom character.

  • Yellow and green colors look red.
  • Orange, red, and yellow look like green.
  • Red looks like black.
  • Red looks brownish yellow, and green looks like a cream color
Color Blind blue-yellow:
  • This type also includes partial color blindness and has the character of:
  • Blue looks green, and it is difficult to distinguish pink from yellow and red.
  • Blue looks like green, and yellow looks like gray or bright purple.

Total color blindness

Unlike the two types above, a person suffering from a type of total color blindness has difficulty distinguishing all colors. Even some sufferers can only see white, gray, and black.

Color Blind Diagnosis

Some people do not realize that they are color blind. That is because they have adapted to the situation. For example, because they know that the color of the leaf is green, then think and assume that the color green is the color they see.

Therefore, checking for color blindness is deemed necessary. In addition to knowing the condition of eye health, the results of the examination also become one of the conditions for a job that requires careful eyes to see colors, such as pilots, engineers, and doctors.

In examining color blindness, there are several types of color blindness tests used by doctors, namely:

  • Ishihara test. The Ishihara test is the most frequently used. In the process, the doctor will ask the patient to recognize the numbers or letters that are faintly printed on the image in the form of colored dots.
  • Color preparation test. In this test, the patient must arrange different colors according to the gradation of the color density.

The doctor can do additional checks to find out the cause of color blindness. If color blindness is caused by an illness or side effects of the drug, the results of the examination are also used by the doctor to determine the appropriate treatment method.

Recognize Color Blindness Early

There is no treatment method that can restore the patient's ability to see color completely. However, patients can train themselves to get used to the color blindness suffered.

For parents, it is important to recognize the character of symptoms and signs of color blindness in children. It is intended that parents can help children adapt to their conditions, so that school activities or their daily lives can continue.

Signs of someone suffering from color blindness can vary, but are easily recognizable. Some of them are:

  • It is difficult to take lessons in school related to color
  • Difficult to distinguish the color of raw and cooked meat
  • Difficult to distinguish the color of traffic lights
  • All difficulties experienced by color blind patients can be reduced by several attempts, such as:
  • Asking for help from relatives or family when experiencing difficult situations related to color, such as when matching the colors of clothes used or seeing whether cooked meat is cooked.
  • Use bright lights at home to help clarify colors.
  • Using available supporting technology, such as special applications that can detect and tell the color of an object.
  • Using a special eyepiece. This special lens can help patients detect certain colors. However, this lens is not always suitable and works effectively in everyone.

If the color blindness experienced is the impact of a disease or side effects of the drug, the doctor will take care of the goal to overcome the cause. Discuss further with the doctor regarding the efforts that can be made so that the color blindness suffered is not too disruptive to the activity.
