Who is Gaurav Khanna In Bigg Boss 19?

Gaurav Khanna has come out as one of the most successful and admired finalists of Bigg Boss 19. Being a calm and emotionally intelligent person with a balanced attitude toward conflicts, he has always been one of the brightest personalities on the show. He is an honest and mature man, and it has been a ride that has made him a fan favourite. His discovery of being colour blind has given viewers a more insightful, wounded insight into him; the more they like a person, the stronger the bond.

What Is Colour Blindness?

Colour blindness (also referred to as colour vision deficiency) is any condition in which an individual experiences impaired ability to differentiate between some colours. The most prevalent ones are red-green colour blindness and blue-yellow colour blindness. This happens when light-sensitive cells in the retina, called cones, do not respond well, or they fail to exist. Colour blindness is not a condition that leaves an individual with the ability to perceive the world in black and white, but rather some colours fade away, look similar or are hard to understand.

What Causes Colour Blindness?

Colour blindness may be caused in a variety of ways, yet the most prevalent issue is the one that is unaffected, which is caused by genetics. It is normally acquired after birth. Other causes include:

  • Age-related vision changes
  • Eye disorders such as glaucoma or cataract.
  • Side effects of some medications.
  • Trauma of the eye or optic nerve.

To most of us, like Gaurav Khanna, colour blindness is an innate phenomenon of life that people get used to since childhood.

How Colour Blindness Affects Daily Life

Being a colour blind person comes with the day-to-day problems like:

  • Problems with dressing or selecting attire.
  • Problems with colour-related tasks.
  • Wrong interpretation of signs or signals.
  • Encounters in games, activities or house chores involving colours.

Nevertheless, against all these odds, the majority of individuals come up with their own specific coping strategies to handle their condition. The story of Gaurav is a strong message that colour blindness has no role to play in causing a person to achieve success in any occupation.

Can Colour Blindness Be Corrected?

Hereditary matters, and therefore, the colour blindness cannot be corrected. Nevertheless, it can be remedied by the use of:

  • Colour-enhancing glasses are used to enhance the contrast.
  • Tinted contact lenses of a special type.
  • Mobile applications, which determine colours by the camera.

In case colour blindness is caused by a medical condition, the colour vision might be treatable by curing the medical condition. However, in the majority of the genetic forms, the disease is permanent.

How Gaurav Khanna Manages His Condition In Bigg Boss 19

Gaurav has managed his condition with dignity and pride in the Bigg Boss house. He might be more complicated with the tasks that require the use of colours, but he could not use his condition as an excuse to withdraw.
