 Color blindness makes it difficult to distinguish between different hues most of the time. Color blindness usually runs in families. Although there is no cure, special glasses and contact lenses can aid with the treatment. Therefore, consulting the best opticians in Bangladesh will be a wise decision. The majority of color blind persons can acclimatize and do not have difficulty with daily activities.

The most common kind of color blindness makes distinguishing between red and green difficult. Another variety makes distinguishing between blue and yellow difficult. Colorblind people are unable to perceive color at all, however, this is a rare occurrence.

Red-green colorblindness

The most common kind of color blindness makes distinguishing between red and green difficult.

Red-green color blindness is divided into four categories:

  • The most prevalent kind of red-green color blindness is deuteranomaly. It intensifies the redness of green. This kind is moderate and normally does not interfere with daily activities.

  • Protanomaly causes red to seem greener and less vibrant. This kind is typically moderate and does not interfere with daily activities.

  • Both protanopia and deuteranopia make it impossible to distinguish between red and green.

 Blue-yellow color blindness

This less prevalent kind of color blindness distinguishes between blue and green and yellow and red, difficult. 

The two types are;

  • Tritanomaly makes distinguishing between blue and green, as well as yellow and red, difficult.

  • You can't distinguish the difference between blue and green, purple and red, or yellow and pink if you have tritanopia. Colors appear to be less vibrant as a result of this.

Complete color blindness 

You can't see colors if you have total color blindness. Monochromacy is another name for this, and it's a rare occurrence. You may have problems seeing clearly and be more sensitive to light depending on the type.

The most common sign of color blindness is the inability to see colors in the same manner that most people do. If you're colorblind, you could struggle to see:

 

  • The difference in hues

  • How vibrant are the colors

  • Colors in various tints

Color blindness symptoms are frequently so subtle that they go unnoticed. Many people with color blindness are unaware that they have it since we have become accustomed to seeing colors in certain ways.

Other symptoms, such as fast side-to-side eye movements (nystagmus) or light sensitivity, may be present in those with severe instances of color blindness.

Color blindness in youngsters can be difficult to diagnose. Color-blind children may try to conceal their condition. However, color blindness might make it difficult to read from a chalkboard or complete other tasks, so if you're concerned, have your child checked.

If your child has a family history of color blindness or is having problems learning colors, have them checked. Make an appointment with your child's eye doctor to get them tested. You might be able to get your child tested at school as well.

 

What causes color blindness ?

The most prevalent types of color blindness are hereditary, meaning they are handed down from one generation to the next. Your color vision will not improve or deteriorate over time if your color blindness is inherited. If you experience sickness or injury to your eyes or brain later in life, you may develop color blindness.

Color blindness is handed down down the generations via chromosomes, which are clusters of genes.

The X and Y chromosomes, for example, decide whether you are male or female at birth. Males have one X and one Y chromosome, whereas females have two X chromosomes. The X chromosome is where the genes that cause red-green color blindness are handed down.

Red-green color blindness is more frequent in men since it is carried down on the X chromosome. Because of the following reasons:

  • Males have just one X chromosome, which they inherit from their mother. They will develop red-green color blindness if that X chromosome carries the gene for red-green color blindness (rather than a normal X chromosome).

  • Females have two X chromosomes, one inherited from their mother and the other inherited from their father. Red-green color blindness requires the presence of the gene for red-green color blindness on both X chromosomes.

Males and females are equally affected by blue-yellow color blindness and full-color blindness, which are handed down on other chromosomes.
