Kids & Colour Vision Impairment

Welcome to our resource for parents of children with Color Vision Deficiency (CVD). We understand that discovering your child has CVD can be a unique challenge, and we're here to provide information and support to help you navigate this journey.

About colour blindness

Color Vision Deficiency (CVD), also known as color blindness, is a visual impairment that affects the perception of certain colors. Children with CVD may have difficulty distinguishing between specific colors or may not perceive them at all.

Early intervention and support can make a significant difference.

How do COLORON colourblind glasses work?

Colour-correcting lenses, like COLORON glasses, filter specific wavelengths of light to enhance colour discrimination. This method can effectively improve colour discrimination and, in the long term, colour identification. You quickly get used to the seemingly uniform hue you experience in the short term (10-15 minutes) and the world becomes more colourful than ever.

Is there a cure for colourblindness?

Currently, there is no cure for Colour Vision Deficiency (CVD). While there are tools and aids to assist individuals with CVD, they don't "cure" the condition but can help with colour perception.

Colour Vision Deficiency (CVD), commonly known as colour blindness, is a condition that affects millions of people worldwide. Before delving into potential cures or treatments, it's crucial to understand the nature of CVD and how it impacts individuals.

How common is colour vision deificiency?

CVD is relatively common, affecting around 8% of men and 0.5% of women of Northern European ancestry. It varies in prevalence across different populations.

Understanding the prevalence of Colour Vision Deficiency (CVD) is essential to appreciate the scope of this condition. It affects a significant portion of the population, with varying degrees of severity.

What are the symptoms of colour vision deficiency?

Symptoms of CVD include difficulty distinguishing between specific colours, frequently confusing colours like red and green, and unusual colour choices in drawings or art.

Recognising the symptoms of Colour Vision Deficiency (CVD) is the first step in identifying and addressing this condition in children. Let's explore the signs that parents and educators should be aware of.

How is colour vision deficiency diagnosed?

Colour vision deficiency is diagnosed through colour vision tests, such as the Ishihara test or the Farnsworth-Munsell 100 Hue Test, administered by eye specialists or pediatricians.

Diagnosing Colour Vision Deficiency (CVD) is a crucial process to ensure that individuals receive the support they need. Understanding the diagnostic methods and the importance of early detection is key.

What causes colour vision deficiency?

Colour vision deficiency is primarily caused by genetic factors and is inherited from parents. In some cases, it can be acquired due to medical conditions or medications.

The origins of Colour Vision Deficiency (CVD) are rooted in genetics, but there are also acquired forms of the condition. Let's delve into the causes and contributing factors.

What are the everyday difficulties and coping mechanisms of living with colourblindness?

Individuals with colour vision deficiency may face challenges in distinguishing colours in daily life. Coping mechanisms include using texture and shape cues, using colour-enhancing tools, and developing adaptive strategies.

Colour Vision Deficiency (CVD) can present daily challenges for children, but with the right strategies and support, they can thrive. Explore how parents, educators, and caregivers can help children cope.

How do colourblind people see the world?

Individuals with colour vision deficiency see the world with altered colour perception. They may have difficulty distinguishing certain colours or perceive them differently than those with normal colour vision.

Understanding the unique way individuals with Colour Vision Deficiency (CVD) perceive colours is both fascinating and enlightening. Gain insights into their world and gain a deeper appreciation for their experiences.

Why is colour blindness more common in men?

The higher prevalence of colour vision deficiency in men can be attributed to genetics. The genes responsible for colour vision are located on the X chromosome. Men have only one X chromosome, while women have two.

Why colour matters

Color is more than just a visual sensation; it plays a crucial role in our lives.

Besides allowing us us to connect and appreciate our surroundings, it lets us perform tasks, hobbies and activities with greater confidence.

It is the functional aspects of color vision which simplify our daily activities and the decision we make during everyday moments.

Although it varies from one person to the next, color deficient individuals may face challenges in various aspects of their daily lives.

EDUCATION AND LEARNING

Interpreting colour-coded information in textbooks, graphs, and diagrams. Distinguishing between colours used for highlighting or organising information.

Potential misinterpretation of colour-based educational materials, such as maps and charts.

OCCUPATIONAL CHALLENGES

Career options in fields that require accurate colour discrimination, such as graphic design, fashion design, and certain scientific research roles.

Challenges in jobs where colour coding is essential, such as electrical wiring or safety instructions that rely on specific colour indications.

SAFETY AND NAVIGATION

Recognising important signals or warning signs that are colour-coded, like traffic lights, road signs, and alerts in industrial settings.

DAILY ACTIVITIES

Issues with colour-coordinated tasks, such as cooking (estimating food doneness), sorting laundry, and matching clothes.

Challenges in selecting ripe fruits or vegetables based on colour cues.

ART AND AESTHETICS

Difficulty appreciating and creating art that relies heavily on colour variations.

Limited ability to differentiate subtle nuances in colour shades, which may impact artistic expression.

SOCIAL INTERACTIONS

Potential misunderstandings related to clothing choices, as well as challenges in coordinating outfits.

Difficulty participating in colour-based games or activities that others enjoy.

ENVIRONMENTAL AWARENESS

Challenges in identifying changes in the environment, such as the changing colours of leaves in different seasons.

EMOTIONAL IMPACT

Potential frustration, especially when trying to explain the condition to others who do not understand colour vision deficiency.

Feelings of exclusion or being different from the others.

Signs & symptoms

Recognising signs of CVD in your child is essential. Common signs include:

Difficulty matching or naming colours correctly.

Frequent confusion of colours like red and green, blues and purples.

Unusual colour choices in drawings or art.

Colour-Coded Games

Children with colour vision deficiency (CVD) may struggle with board games or card games that rely on colour distinctions, like Uno or Connect Four.

Ripe Fruits

Identifying the ripeness of fruits like bananas, avocados, or strawberries can be challenging for individuals with CVD, leading to potential issues in selecting fresh produce.

Traffic Light Signals

Difficulty in differentiating between the colours of traffic lights, such as confusing red with green, can pose safety concerns for individuals with CVD while driving or crossing streets.

Art Class

In art class, children with CVD may have trouble selecting and using the correct colours, impacting their ability to accurately represent objects or scenes.

Colour-Coded Maps

Reading maps that use colour-coding for various elements, like geographical features or public transportation routes, can be problematic for those with CVD.

Colourful Clothing

Coordinating outfits and matching colours in clothing and accessories may present a challenge, potentially leading to fashion choices that stand out or mismatch.

What to do next?

If you suspect your child may have colour vision deifciency or notice signs of colour vision difficulties, consult a healthcare professional for an evaluation and take our free online test.

Pediatricians and eye specialists can diagnose CVD through colour vision tests, such as the Ishihara test or the Farnsworth-Munsell 100 Hue Test. These tests help determine the type and severity of CVD.

How to support

Supporting Your Child

As a parent, you play a vital role in supporting your child with colour vision deficiency (CVD).

Encourage open communication, provide emotional support, and foster self-confidence. Remember that colour vision problems don't define their abilities.

Educational Considerations

CVD may affect your child's performance in school, especially in subjects like art or science. Collaborate with teachers to ensure they receive the necessary accommodations and support.

Daily Life

Practical tips for everyday life, including choosing clothing with colour contrasts, labeling items, and selecting art supplies with distinguishable colours.

Use Texture and Shape Cues Alongside Colour

Instead of relying solely on colour coding, incorporate textures, shapes and numbers to help distinguish objects or instructions. For example, use different shapes of stickers or labels for organising belongings or files, or assign numbers to different folders or subjects instead of using coloured folders for organisation.

Provide Colour-Correcting Tools

Invest in colour-discrimination tools provided by companies such as COLORON that can help your child choose and use colours more accurately in their drawings and assignments, during outdoor activities and also during screen time.

Teach Adaptive Strategies

Encourage your child to develop adaptive strategies such as memorising colour patterns and using contextual cues. For instance, they can identify traffic lights based on the position (top for red, middle for yellow, bottom for green) rather than relying solely on colours.

Choose Colourblind-Friendly Art Supplies

When purchasing art supplies, opt for those with easy-to-distinguish colours and clear labels. Consider using colour names on paint tubes or markers to help your child learn and identify colours by name.

Foster Inclusive Play

Encourage inclusive play by selecting games and activities that don't heavily rely on colour distinctions. Board games with distinct symbols, shapes, or numbers are excellent choices.

Label Clothing and Belongings Clearly

Sew or attach clear labels with your child's name or descriptions of clothing items to make it easier for them to identify and match outfits.

Assist in Homework and Assignments

Help your child with colour-dependent assignments by offering guidance, describing colours verbally, and using colour-correcting aids if available.

Create a Colour-Friendly Environment

When designing your child's room or play area, consider using contrasting colours for walls, furniture, and decor to make it easier for them to navigate and identify objects.

Encourage Open Communication

Foster open communication with your child and their educators. Make sure teachers are aware of your child's colour vision deficiency and collaborate on strategies to support their learning needs.
