Sadly, there are some people living with either total or partial color blindness. The disorder which is also termed as Color Vision Deficiency (CVD) is a condition where you’re unable to differentiate between the basic red and greens or yellow and blues. Most do not even realize they have the condition until their friend or family tell them. Or they apply for jobs like astronauts or web designers, where knowing the exact colors and their coherence is important.

My point is, it’s better to find out whether or not you’re color blind so that you can adapt treatment measures and cope up with it. That is why I have prepared this article so that you know everything about colorblindness, it’s causes, diagnosis, and treatment.

So What is Color Blindness?

1 in 200 women and 1 in 12 men are color blind. There are approximately 3 million color blind people all around the world who have the common form of red-green color blindness. But what is color blindness? Is it the complete loss of color perception and vision? Is it a form of blindness?

NO. Color blindness is an inherited deficiency in the way you see or distinguish certain colors such as blue and yellow. Though it does not sound scary, living with color blindness is definitely not fun.

Types of Color Blindness

The most common type of color blindness is the red-green color deficiency. Normal vision uses all three types of light cones and hence called trichromats. But surprisingly, people who are color blind are born with faulty trichromatic visions. Hence, depending on which type of light cone is faulty in their eyes, there are different other rare types of color blindness disorder known to affect humans. It includes:

 

Tritanopia

    • Red-Green Color Blindness: Here, the person has reduced sensitivity to red and green color. They have difficulty differentiating the red, greens, browns and oranges. People who have reduced sensitivity to red light are known as protanomaly and those who have reduced sensitivity to green light are known as deuteranomaly. Protanopes are likely to confuse some blues with reds, purples and dark pinks whereas deuteranopes are likely to confuse mid-reds with mid-greens, pale pinks with light grey and so on.
  • Tritanomaly: It is a rare form of color blindness where a person is cannot differentiate blue colors. Tritanopes (people with tritanomaly) have confusions differentiating light blues with greys, dark purples with black, mid-greens and blues and oranges with reds.
  • Blue-yellow Color Blindness: It is the type of color blindness involving the inactivation of the short-wavelength sensitive cone system aka Tritanopia. It equally affects males and females. These people cannot differentiate yellow from pink and purple colors are perceived as various shades of red.
  • Total Color Blindness or Achromatopsia: Achromatopsia is an extremely rare condition affecting only 1 in 33,000 persons. The condition results in a partial or total absence of color vision. Those who have complete achromatopsia only see black, white an shades of grey. Achromatopsia also involves other problems with vision, including an increased sensitivity to light and glare (photophobia), involuntary back-and-forth eye movements (nystagmus), and significantly reduced the sharpness of vision (low visual acuity).

Causes of Color Blindness

Human eye consists of light-sensitive cells in the retina. Any defect or lack of these light-sensitive cells results in color blindness. The two major photoreceptors in the retina are rods and cones. Rods are photoreceptor cells while cone cells help to perceive colors. Certain inherited deficiencies in the cones or absence of certain cones result in color blindness. Heredity aside, other causes of color vision defects include:

  • Cataracts: Cataracts causes clouding in the eye’s lens that can destroy the cone cells, making it appear a wash out the color vision.
  • Parkinson’s Disease:  As Parkinson’s disease is a neurological disorder, light-sensitive nerve cells in the retina where vision processing occurs may be damaged and cannot function properly.
  • Tiagabine for epilepsy. Tiagabine drug that’s prescribed for the epileptic patient can cause reduction in the color vision in about 41 percent of those taking the drug, although effects do not appear to be permanent.
  • Kallman’s Syndrome: Here, the patient’s pituitary gland fails to function completely due to the inherited condition. This can result in unusual gender-related developmental disorder like lack of sexual organs. Color blindness can also be one of the symptoms of this disorder.
  • Aging: Color blindness also can occur when aging processes damage retinal cells. An injury or damage to areas of the brain where vision processing takes place also can cause color vision deficiencies.

Color Blindness Symptoms

The obvious symptom of color blindness is difficulty in distinguishing colors like blue and yellow or red and green. People with partial color blindness can see colors but only in their dull version.

If you develop color vision problems when normally you have been able to see a full range of color, then you definitely should visit your doctor. Sudden or gradual loss of color vision can indicate any number of underlying health problems, such as cataracts.

Is Colorblindness Treatable? Treatment of Color Blindness

Sadly, there’s no permanent cure for color blindness. However, a research study conducted in 2009 by researchers at the University of Washington and University of Florida showed that gene therapy cured color blindness in monkeys. Nevertheless, human trails are yet to be conducted.

Living with colorblindness can feel like the world is pretty dull, but there are always treatment methods available to treat the condition. Most people use correction glasses and lenses to enhance their color perception. These types of glasses and lenses should be used only after consulting with expert eye care practitioners. Above all, you can seek help from your partner or family member to help you deal with day-to-day problems distinguishing colors. You can label your clothing or other items to avoid color clashes. You can also try remembering the color of items on the basis of their order.

Not only this, there are tons of new apps that help to detect the color of an item online. You can use them too!
