What is Color Blindness?

An overview

Color blindness is basically an inaccurate term to provide a description of lack of perceptual sensitivity for various colors, a more precise term is rather Color Vision Deficiency (CVD). Color blindness is basically a color vision deficiency in which there are certain colors, which cannot be distinguished. This is generally an inherited eye condition among which red and green color blindness is most common, or it may be caused by retina or optic nerve disease and is about 99%.

Total color blindness, however, is very rare. There is neither any significant treatment of color blindness nor it can cause any specific disability, but it is rather frustrating for those suffering from it.

Clinical Information

Color sensitive receptor cones contain single visual pigments for green, red and blue light in a normal human eye but in case of color blindness only one pigment is present.Color vision is due to another eye disorder but majority of the cases are hereditary. Color blindness is most common in males and is transferred by mothers as females are carriers of color blindness.

Symptoms of color blindness

There are many factors on which color blindness depends whether this problem is partial, acquired, congenital or even complete. These are listed as:

  • Difficulty to distinguish between red and green
  • Difficulty to distinguish between blue and green
  • Complete color blindness i.e. inability to distinguish between various shades of gray
  • Nystagmus
  • Reduced vision

What are different ways of diagnosis and detection?

Deficiency of color vision is detected with color vision charts called Ishihara Test Plates. Each plate has numbers, which are composed of colored dots. So a color blind person is asked to identify the colors being held this chart in the presence of good lightening.

Once this color defect is recognized, many other tests are then performed for detailed investigation.

General Treatment

As mentioned above there is no specific treatment available for color blindness.

Persons having a mild ailment try to associate the colors with certain objects, and then they can identify the colors as everyone can. However, the problem with them retained that they can’t acknowledge the full characters as the persons with normal color vision.
