Color Blindness: Is It Dangerous?

Color Blindness: Is It Dangerous?

January 11, 2023

People who are color blind have numerous challenges in their daily lives that normal people are simply unaware of. Even the simplest activities, like choosing and cooking food, gardening, playing sports, operating a motor vehicle, and deciding what to wear, might present challenges. Color vision deficiency (CVD) or color blindness is also termed "poor color vision."

What is color blindness?

If you’re color blind, you see colors differently from the majority of people. Color blindness frequently makes it challenging to distinguish between particular colors.

Color blindness typically runs in families. Specialized glasses and contact lenses can help, but there is no cure. The majority of color blind people are adaptable and have little trouble going about their daily lives.

Instead of the reds, greens, and teals that others see in color charts, most color blind people see the following hues:

  • Yellow
  • Gray
  • Beige
  • Blue

What are the types of color blindness?

Red and green color blindness:

  • The most prevalent type of color blindness
  • This kind of color blindness can make it challenging for a person to distinguish between red and green in any situation.
  • Cone cells (a type of specialized retinal cells) are not fully developed to distinguish red and green colors , as there are no light-sensitive pigments present.

Blue and yellow color vision deficiency:

  • Blue and yellow color blindness is less common
  • The cone cells that are in charge of recognizing blue and yellow colors are immature and defective due to the absence of light-sensitive pigments.
  • Blue is frequently confused with green when people are trying to understand it, and yellow is frequently mistaken for blue.

Complete color blindness:

  • The most severe and uncommon type of color blindness.
  • This type of color blindness renders the sufferer completely color blind.
  • Since none of the cone cells responsible for determining color react to color, the only colors the person can sense are black, white, and grey.

What causes color blindness?

The most prevalent types of color blindness are hereditary, or passed down from one’s parents.

Damage to the eye or the brain can also result in color blindness. Additionally, as you age, your color vision may deteriorate as a result of cataract.

What are the signs and symptoms of color blindness?

Being unable to perceive colors as most people do, is the basic sign of color blindness. If you’re color blind, it could be challenging to see:

  • The difference between colors
  • Different shades of colors
  • The intensity of the colors

The signs of color blindness can frequently be so subtle that you might not even notice them. Many people who are color blind are unaware of their condition since we grow accustomed to how colors appear to us.

Other symptoms, such as nystagmus or sensitivity to light, may also be present in those with very severe cases of color blindness.

Am I at the risk of color blindness?

Compared to women, men are far more likely to be color blind. Having color blindness is also more likely if you:

  • Have a history of color blindness in your family
  • Take specific medications
  • Possess certain eye conditions, such as glaucoma or age-related macular degeneration
  • A specific medical condition, such as diabetes, Alzheimer’s disease, or multiple sclerosis
  • Optic neuritis or any other form of damage to the optic nerve.

If you suspect that you may be color blind, discuss having a test done with your doctor.

How is color blindness diagnosed?

A color vision test, often known as the Ishihara color test, assesses your ability to distinguish between colors. If you don’t pass this test, you might have defective color vision.

Several problems with color vision can be found using this test, including:

  • Protanopia:  inability to distinguish red
  • Tritanopia: difficulty in identifying blue
  • Deuteranopia: inability to recognize green.
  • Complete color blindness: also known as, achromatopsia
