What is Color Blindness?

Color blindness is a condition in which you view colours differently than most people. Color blindness makes it difficult to distinguish between different colors most of the time.

Color blindness usually runs in families. Although there is no cure, special glasses and contact lenses can aid in the treatment. The majority of colour blind people can adapt and do not have difficulty with daily activities. 

We go over the various types of colour blindness and the new and upcoming treatments for the illness.

What is Color Vision Deficiency (CVD)

Color vision deficiency (CVD) affects people's ability to perceive colours in the same manner that the rest of us do. Light sensitivity affects three types of cone cells in our eyes, which help us recognise colour. When people can't see colours well, it's because one of these cone cells is missing. The missing of a cone cell impairs vision in a portion of the light spectrum, affecting colour perception.

Color perception issues can affect daily life in a variety of ways, from not being able to tell if your banana is ripe to failing to notice when your skin is sunburned. Although the red and green lights may not be seen, the brightness of the light, as well as common knowledge that red is at the top, amber is in the middle, and green is at the bottom, are usually not an issue.

Three types of Colour Blindness

Color blindness can be classified into three categories:

  • When people have tritanopia, they can't tell the difference between blue and yellow.
  • Protanopia is a condition in which people have difficulty distinguishing between red and green.
  • Monochromacy, also known as achromatopsia, is a condition in which people are unable to distinguish between colours. This disorder causes people to see the world in black and white.

What does it feel like to be colorblind?

Color deficiency affects people in varied degrees of severity. Some people can see colours very well in excellently situations, but struggle to perceive colours in dark room environments. Some people have trouble detecting the difference between colours in bright and bad light. A small percentage of people are colorblind and see the world with a grey tint, although these are exceptional cases.

What is the percentage of colour blindness?

Color blindness affects one in every 12 men and one in every 200 women on the planet. Color vision deficiency affects 3 million persons in the United Kingdom, the majority of whom are men.

Is colour blindness a hereditary condition?

Color blindness is mostly inherited, but it can also be caused by illnesses, medications, eye injuries, and eye diseases such age-related macular degeneration. Because the illness is passed down through the X chromosome from father to kid, it primarily affects men rather than women.

A loss of colour vision can occur later in life; but, once identified, the degree of the blindness usually remains the same. Contact your optician if you are colorblind and observe a change in how you see colours. Or you can get consultation from our Malaya Optical Optometrist by booking your appointment here.

Is colour blindness curable?

Color blindness currently has no treatment. Dyed contact lenses, on the other hand, may aid with the symptoms of colour vision deficiency, according to accumulating data. A coloured contact lens produced by researchers at the University of Birmingham could help individuals see colours more clearly.

The dye is both fully safe and affordable to use. Contact lenses and spectacles could both benefit from the dye. There are already sunglasses available to aid color vision.
