Color is what we believe to be self-evident. It makes the world all the more beautiful to be able to see and enjoy it. However, it may be a job for some children because they can not see the color of the average person’s results. Understanding what that means will help your child live less troubled lives.

What is Colour Blindness in Toddlers?

Color blindness, also known as a lack in color vision, is an issue in which a child is unable to see such colors the way they actually appear. Children with color blindness also have difficulty distinguishing between shades of a color. When a child is presented with red, blue, and green colors, the disorder is most evident.

Causes of Colour Blindness

The retina of the eye consists of two types of cells – rods and cones. The rods are responsible for detecting the light while the cones sense the color. The eye consists of three forms of cones, namely red, blue, and green. The loss of one or more of these cones contributes to the blindness of color. Analysis has shown that the disease is genetic.

How To Check That Your Child Is Color Blind

  • Will he use the wrong colors when he paints or uses coloring books? Example – Red leaves instead of green, orange stems instead of brown ones, etc.
  • Is it difficult for him to see or work with colors?
  • When looking at red against green or green against red, does he complain of a headache or eye pain?
  • Is he uncomfortable with coloring books or sheets that use colors on colors?
  • Does he have a very good night vision or a lower light sensitivity?
  • Is he sometimes unintentionally move his eyes?

Types of Colour Blindness in Toddlers

1. Problem In Differentiating Between Green/Red and Brown/Orange

One of the color detection cones is absent in this form of blindness, called dichromacy, rendering the eye sensitive to certain colors. A child with dichromacy can find it difficult to distinguish between green and red and may also blend in brown and orange.

This color blindness is caused when two colored cones in the eye are absent, also known as achromatic or monochromatic. A kid with the disorder can only see the world in black and white colors.

2. Problem With Seeing Red, Green, and Blue

This is called anomalous trichromacy and happens if color-detection cones in the retina are slightly maladjusted. It is also known as protanomaly, deuteranomaly, and tritanomaly. Reduced red color sensitivity results in protanomaly, while green sensitivity results in deuteranomaly. Tritanomaly occurs if the eye has a low blue sensitivity.

Challenges Of Colour Blindness in Toddlers

Many activities we do every day depend on the ability to differentiate objects by their color. Color vision loss occurs at various degrees. Color vision also can be affected by light intensity and object size.

If you can’t see the color difference, you must depend on other signals. For example, only the red and green lights can be differentiated by their location (red above green). This can be hard to do on a dark, wet night.

A specially designed graphics can be used for color vision research by ophthalmologists and optometrists. Some school health programs can also assess the color vision of children.

Further tests may be required to assess the exact nature of the impairment if color vision impairment is detected.

Deficiency in color vision is very normal and has little effect on the long term health of a child.

Treatments For Color Blindness In Toddlers

As of now, color blindness in toddlers can not be treated. While physicians recommend colored lenses to improve color intensity, they are not very helpful. Tests are nevertheless in progress to produce a cure. In the meantime, commend your child when he recognizes a color correctly. Buy colored pencils and pens as he grows. Providing good support for him will instill trust in him.

Color blindness is an irregular disorder caused by the inability of the spectrum to clearly differentiate various colors. The challenges can vary from mild to serious. As individuals with color blindness are not blind, it is a misleading term. Rather, in a small range of hues, they appear to see colors; a rare few do not see colors at all.
