What is Colour Blindness ?

Color blindness is characterized by the inability to perceive certain colors or difficulties in distinguishing between specific colors due to the absence or malfunction of certain light-sensitive receptors, known as cones, in the retina of the eye.

Individuals may be considered color blind if they have reduced sensitivity to particular colors or have challenges in differentiating combinations of certain colors. For instance, some individuals may struggle to distinguish between red and green, while others with color blindness may face difficulties in distinguishing between blue and yellow.

Complete color blindness is exceptionally rare and is typically diagnosed early in an individual’s life. However, other forms of color blindness may go unnoticed and can have adverse effects if one aspires to join the Indian Army.

Color blindness can be either genetic or the result of injury to the brain or eyes. It can be identified through various tests, with the Ishihara Color Blindness Test being the most commonly used method to detect color blindness.

What is Ishihara Colour Blindness Test ?

The Ishihara color blindness test, often referred to as the Ishihara test, is a crucial assessment employed in the selection process for eligible candidates in the Indian Armed Forces. This test is designed to evaluate color vision, particularly red-green color deficiencies.

The Ishihara Color Blindness test is also used by the Indian Railways for specific positions and the Indian Armed Forces during the SSB and other recruitment procedures to screen for color blindness in candidates.

In a traditional Ishihara Color Blindness Test, individuals are presented with a series of 14 colored dotted plates, each containing a hidden path, pattern, or number within a set of colored dots. A person with normal vision should be able to correctly identify the digits or paths in at least 12 of these plates.

During the medical examination for the Indian Armed Forces or the Indian Railways, candidates are provided with a book containing alphabets, digits, or paths printed in various colors on dotted backgrounds. Aspirants are required to verbalize their observations in front of a panel of doctors and an authorized ophthalmologist.

The Ishihara Color Blind Test, or the Indian Army color vision test, may include different types of designs:

  1. Vanishing designs: Only individuals with normal color vision can perceive the sign, while color-blind candidates won’t see anything.
  2. Transformation designs: Color-blind individuals perceive a different sign or pattern compared to those with normal vision.
  3. Classification designs: These are used to differentiate between individuals with red and green color blindness and typically contain vanishing designs on both sides to detect Deutan defects.
  4. Hidden digit designs: In these cases, people with perfect color vision won’t see any digits, but color-blind individuals can perceive the digit(s).

Candidates are graded as CP1, CP2, CP3, or CP4 based on their color perception. The results of the Ishihara color blindness test or the Indian Army color vision test are typically available immediately.

Color blindness can potentially lead to medical disqualification in recruitment processes such as the NDA or Combined Defense Services (CDS) for the Indian Armed Forces.

To join the Indian Army, a minimum color perception grade of CP3 is required. For any branch of the Indian Air Force, a CP1 is necessary. The eligibility for the Indian Navy may be either CP1 or CP2, depending on the role and recruitment process. It is strongly recommended to refer to the official notification of the recruitment process to understand the specific eligibility criteria for your desired role in any of the Indian Armed Forces or the Indian Railways.
