One of the main benefits of colour-correcting glasses is improved colour differentiation. Rather than “fixing” colour blindness, these lenses are designed to enhance contrast between certain colour wavelengths. This can make colours easier to distinguish in everyday situations such as reading charts, selecting clothing, recognising coloured signals or engaging in creative pursuits. Many wearers describe colours appearing brighter, clearer or more separated than before.

Another advantage is confidence. Tasks that previously caused frustration — interpreting coloured diagrams, identifying traffic lights against complex backgrounds, or participating in visually driven hobbies — may become more manageable. For children and teenagers in particular, this can positively influence self-esteem, learning engagement and social inclusion.

However, colour-correcting glasses are not without limitations. Results vary significantly from person to person, depending on the type and severity of colour vision deficiency. Some users notice an immediate difference, while others experience more subtle changes, or little change at all. This variability is why professional assessment and guided testing are essential.

Lighting conditions also matter. Colour-correcting lenses tend to perform best in natural light and may be less effective indoors or under artificial lighting. In certain environments, colours may appear exaggerated or unnatural, requiring an adjustment period.

Another important consideration is adaptation. The brain has spent years interpreting colour in a particular way. Introducing altered visual input can feel disorienting at first, and some wearers report eye fatigue or sensory overload during early use. Gradual wear and professional guidance can help manage this transition.

Finally, colour-correcting glasses are not designed to replace standard vision correction. People who require prescription lenses need options that address both visual acuity and colour perception, which further reinforces the need for expert optometric advice.

When approached realistically and with proper support, colour-correcting glasses can be a valuable tool for some people with colour vision deficiency. The key lies in understanding both their potential and their limitations.

Colourblindness is a visual condition that affects how certain colours are perceived, most commonly red, green, or blue tones. Autism, on the other hand, is a developmental difference that can influence social interaction, communication, sensory sensitivity, and how a person experiences the world. While they are separate conditions, many people live with both—and understanding how they interact is an important step toward better support.

A Sensory Puzzle

Children and adults on the spectrum often have heightened or reduced sensitivity to sensory input. For some, colours may appear too bright or too dull, patterns too distracting, or lights too harsh. Add colour vision deficiency into the mix, and it becomes harder to navigate visual cues that others take for granted.

Imagine trying to understand a school timetable colour-coded by subject, or a traffic signal, or even reading a chart at the doctor’s office—without being able to clearly distinguish between the colours. For neurodivergent individuals who already rely heavily on routine and predictability, these visual challenges can create unnecessary anxiety or frustration.

Missed or Misunderstood

Unfortunately, because autism is often the focus of clinical care, colour vision differences can go unnoticed or dismissed. A child’s difficulty with visual tasks may be attributed to “behavioural” issues or assumed to be related solely to their autism, when in fact, they may also be struggling to see the colours correctly.

That’s why early, accurate testing is important. When we understand the full picture of how a child or adult processes the world—including how they see colour—we’re better placed to make practical changes that support them in everyday life.

Simple Tools, Real Impact

The iRo Lens testing kit offers a simple, non-invasive way to identify colour vision deficiencies from home. For individuals on the autism spectrum, the familiar and comfortable environment can make testing less stressful and more effective. There’s no need for a clinical visit or confusing instructions—just an accessible, straightforward way to understand how someone sees the world.

With clear results in hand, families, teachers, and carers can make thoughtful adjustments. This might include using textures, shapes, or words alongside colour codes, choosing more accessible clothing combinations, or modifying learning materials. These small changes can significantly reduce frustration and increase independence.

Understanding Builds Confidence

Living with both autism and colour vision deficiency doesn’t have to be a struggle—it simply requires a deeper understanding and the right tools. At Colour Vision Optical, we believe in meeting people where they are and giving them the information they need to thrive.

With the right insight and support, the world doesn’t have to be confusing. It can start to make sense—in all its shades.

What I didn’t know back then was that my grandfather had the same experience. He worked as a tradie, and would often laugh about painting walls the “wrong” shade or buying the “wrong” colour of flowers for my grandma. It was always treated as a bit of a family joke—nothing serious. But in hindsight, I wonder how many opportunities he quietly avoided because of it.

Later, my own son started showing similar signs. He’d complain that colouring-in at school was “too hard” or that he didn’t like playing board games with coloured pieces. At first, I assumed he was just being fussy. Then I remembered what it felt like to be a child constantly second-guessing what others saw so clearly. The pattern was repeating itself.

That’s when I decided to stop the guessing game.

We used the iRo Lens testing kit, which gave us clear, reliable results right from home. No appointments, no waiting lists—just straightforward insight. Sure enough, my son had a form of red-green colour vision deficiency, just like me.

Having that knowledge was empowering—for both of us. It allowed his school to make small changes, like labelling colours on charts and choosing learning materials with better contrast. It also gave him the words to explain what he sees, which made a big difference in building his confidence.

Looking back, I realise how many small moments of confusion or frustration could have been avoided—for me, for my grandfather, and now, hopefully, for my son. Colourblindness isn’t a disability in the traditional sense, but it does shape how we interact with the world. And when you don’t know what you’re dealing with, it can quietly chip away at your confidence.

That’s why I believe in the importance of early testing and open conversations. Not so kids can be labelled, but so they can be understood—and supported.

Three generations of my family have navigated the world a little differently. And thanks to awareness and tools like the iRo Lens kit, the next generation won’t have to do it alone or in silence.

If you’ve ever suspected you—or someone you care about—might have a colour vision difference, don’t wait decades to find out. Knowing how you see colour is one small step that can open the door to a lifetime of clarity.rough education and understanding.

The post Colourblindness Through the Generations: My Story appeared first on Colour Vision Optical.

From childhood, colour is tied closely to gender. Pink for girls, blue for boys. Brightly coloured toys, clothes, and books are often marketed with strong visual cues. For children with colourblindness, navigating these expectations can be confusing or frustrating—especially if they’re told they’ve picked the “wrong” colour or misidentified something in a way that draws unwanted attention.

Masculinity, stigma, and silence. 

Because colourblindness is far more common in males, boys are often the first to face teasing or embarrassment in the classroom. They may misread a colour-coded chart, struggle with art assignments, or mismatch clothing—then be laughed at or told they’re not paying attention. Instead of seeking help, some boys learn to stay quiet, adapt silently, or avoid colour-based tasks altogether.

Cultural norms around masculinity can make it harder to admit difficulty or ask for support. Over time, this can lead to feelings of shame or underconfidence—not because of the condition itself, but because of the way society responds to it.

Women and underdiagnosis

On the flip side, colour vision deficiency is often overlooked in females. Around 1 in 200 women have it, but because it’s less expected, it may not be picked up early—or at all. Girls may find themselves labelled as inattentive or forgetful for making colour-based mistakes,
without anyone realising there’s a genuine reason behind it.

Additionally, the stereotype that women are naturally more attuned to colour (used in everything from fashion commentary to workplace assumptions) can make it even harder for colourblind women to speak up. They might feel they’re “not supposed” to have difficulty,
and as a result, may keep it to themselves.

Unpacking expectations and supporting everyone

Navigating gender roles and colourblindness means recognising how deeply cultural norms affect how the condition is perceived and experienced. Whether it’s a teenage boy
embarrassed to admit he can’t tell if his tie matches, or a young girl who quietly avoids colouring-in tasks at school, support needs to be empathetic, inclusive, and free from stereotypes.

That begins with proper identification. The iRo Lens testing kit provides a quick, easy way to test for different types of colour vision deficiency from home—no clinic visit needed, no assumptions made. Whether you are exploring colourblindness for yourself or a loved one,
getting accurate insight can be the first step toward greater confidence and clarity.

Breaking down gender expectations doesn’t just benefit those with colour vision deficiency—it benefits everyone. It creates space for honesty, support, and practical solutions, regardless of who you are or how you see the world.

Contrary to what some believe, being colourblind doesn’t mean seeing the world in black and white. Most people with colour vision deficiency see colours—just differently. The majority have red-green colourblindness, which makes it harder to distinguish between shades like red,
green, brown, or orange. For others, blue and yellow may be tricky. But the key thing to remember is: colourblind people are not “broken”—they simply see the world a little differently.

Challenging Common Stereotypes
One of the most common misconceptions is that colourblind individuals are less capable—especially in fields that use colour coding, such as design, engineering, healthcare, or education. But many people with colour vision deficiency thrive in these roles, often developing sharper pattern recognition and stronger problem-solving skills to compensate.

Another stereotype is that colourblind people can’t appreciate art, fashion, or creativity. In fact, many artists and designers have colour vision differences—and their unique perspective is part of what makes their work so distinctive. There’s also a social stigma—being called out or laughed at for choosing mismatched clothes or misreading a colour-coded chart. For children, this can be particularly damaging,
especially in classroom environments where coloured markers, maps, or visual aids are used without accommodations.

Normalising Colour Vision Differences
One of the most powerful ways to combat stigma is through education and awareness. The more we understand that colour vision deficiency is common (affecting about 1 in 12 men and 1 in 200 women), the less likely we are to treat it as a flaw or a punchline.
For schools and workplaces, this means creating more inclusive environments: using labels as well as colour in charts and diagrams, offering alternative visual cues, and avoiding assumptions about what someone can or can’t see. For individuals with colourblindness, it can mean embracing your difference rather than hiding it. Speaking up—whether it’s asking for a non-colour-coded version of a task or
explaining how you navigate the world—helps others understand and adjust.

Tools That Empower
Understanding your specific type of colour vision deficiency can be empowering. It allows you to advocate for the right accommodations, find workarounds that suit you, and explain your needs more clearly.

The iRo Lens testing kit is an easy, at-home tool that provides insight into how you see colour. It removes the guesswork and offers a clearer picture (literally and figuratively) of your own colour profile—making it easier to work with, not against, your vision.
By breaking down the stigma and embracing a strengths-based perspective, we can shift the conversation from what people with colour vision deficiency can’t do to all the things they can—often with clarity, creativity, and confidence.

The post Combating Stigma and Stereotyping as a Colourblind Person appeared first on Colour Vision Optical.

Let’s break down the most common types:
1. Red-Green Colourblindness (the most common type)
This group of conditions is the most widespread, particularly in people assigned male at birth. It includes:
 Protanopia: Individuals with protanopia have very limited sensitivity to red light. Reds may appear dull, brownish or even black, and purples may look blue because the red component is missing.
 Protanomaly: A milder form where red is not completely absent but appears weaker or “muddy”. People may confuse reds with greens, especially in low lighting.
 Deuteranopia: Similar to protanopia, but with reduced sensitivity to green light. Greens may appear more like beige or grey, and reds and greens can be hard to tell apart.

 Deuteranomaly: The most common form of red-green deficiency. Greens may appear reddish, and colour matching can be difficult. Many people with deuteranomaly don’t realise they have it until tested.

2. Blue-Yellow Colourblindness (less common) This group is rarer and affects how individuals perceive blue and yellow hues.
 Tritanopia: People with tritanopia lack blue cone cells, making it hard to distinguish between blue and green or yellow and pink. The world may appear more red and
green than it actually is.
 Tritanomaly: A milder version of tritanopia where blue-yellow discrimination is still affected, but not as severely.
3. Total Colourblindness (very rare)
 Monochromacy: This is the rarest and most severe form. People with monochromacy see no colour at all—only shades of grey. It’s often accompanied by sensitivity to
light and poor visual acuity.

Why Knowing Your Type Matters
Understanding your specific type of colour vision deficiency can help with daily tasks, career planning, and even improving visual accessibility. For children, it may explain difficulties in
the classroom. For adults, it can influence choices in everything from clothing to workplace safety.

That’s where the iRo Lens testing kit comes in. Designed for home use, it provides an easy, accurate way to identify your colour vision profile. No long wait times or specialist
appointments—just clear answers you can act on. If you wish to see a Colour Vision specialist we have a range across Australia, click here to locate your nearest one.

Whether you’ve always suspected you see colour differently or you’re exploring it for someone else, knowledge is the first step. And with tools like the iRo Lens kit, that step has never been easier.

Let’s take a look at how being colourblind can be an asset in certain professions.

1. Graphic Design and UX Testing
   While it may sound surprising, colourblind individuals can offer valuable insights in graphic design—particularly in user experience (UX) testing. Because they don’t rely on colour as heavily, colourblind testers can identify flaws in design that may not be apparent to others. For example, they’re more likely to notice if information is conveyed using colour alone (a known accessibility issue), prompting designers to include additional text, shapes or icons. Their input helps make websites and apps more inclusive and easier to navigate for all users.
2. Military and Camouflage Detection
   In some branches of the military, colourblindness has been seen as an advantage when it comes to spotting camouflaged objects. While those with typical colour vision might be “fooled” by colour patterns designed to blend into the environment, colourblind individuals often focus on texture, shape and movement rather than colour. This can make certain camouflaged items stand out more clearly to them.

Historically, some colourblind individuals have even been selected for specific roles in visual detection and surveillance.

3. Data Analysis and Coding
   In fields like coding, statistics or finance, success depends more on logic, structure and critical thinking than on colour perception. Colourblind professionals often excel in identifying patterns, errors or inconsistencies in large data sets because they’re not relying on colour cues to interpret information. Instead, they develop strong alternative strategies, such as focusing on shape, spacing or position, to detect issues quickly and accurately.
4. Quality Control and Manufacturing
   In some manufacturing roles, particularly where surface texture or defect detection is key, being less sensitive to colour can actually sharpen attention to detail. Workers with colourblindness may be more attuned to imperfections, inconsistencies in texture, or subtle variations in form that others might overlook.
5. Fashion and Photography (with a twist)
   While colour perception might seem critical in creative fields, colourblind photographers or stylists often develop a keen sense of contrast, lighting and composition. Rather than relying on colour balance, they focus on structure, emotion, and mood—producing bold, impactful work that stands out for its style rather than its palette.

Seeing Differently Is a Strength
While colourblindness does present challenges in daily life, it’s also a reminder that different ways of seeing can be powerful. In certain professions, colour vision deficiency encourages problem-solving, out-of-the-box thinking, and stronger reliance on other senses and visual cues.

How iRo Lenses Can Help
For those with colourblindness who want more flexibility—both in daily life and professional settings—iRo Lenses can offer support. These specially designed lenses enhance colour discrimination by filtering specific wavelengths of light, making it easier to distinguish between commonly confused shades. Whether you’re reviewing colour-coded data, collaborating on creative projects, or simply navigating a colourful world, iRo Lenses help bring clarity and confidence where it matters most.

But for parents living with colourblindness, there’s a quiet heartbreak that often goes unseen. When you can’t see colours the way your child does, interpreting their artwork becomes a challenge. And worse—sometimes you get it wrong. That ” colourful rainbow” looks grey, the ‘green’ giraffe? It was yellow. The grey blob you assumed was a rock? It was meant to be a bright red heart.

What It Feels Like
Colourblindness affects how you perceive and differentiate between certain colours, most commonly reds, greens, and browns. For someone with colour vision deficiency, two colours that seem completely different to others might look almost identical. This can lead to awkward or upsetting moments—especially when trying to connect with your child through something as personal as their creative expression.

Imagine your child excitedly handing you a picture they’ve spent ages on, only for you to struggle to make sense of it. You smile, nod, and guess—but your child gently corrects you, pointing out that the sky is purple, not blue, and the tree is orange, not green. It’s not just about getting colours “wrong”—it’s about feeling like you’ve missed a little piece of their world.

Losing Out on Shared Moments
These small missteps can carry a heavy emotional toll. Colourblind parents often express sadness over the idea that they’re not experiencing their child’s imagination the way it was intended. It’s not about needing to see every colour perfectly—it’s about wanting to truly connect. When your child says, “I made this for you!” there’s a desire to see it as they see it.

Over time, this disconnect can lead to frustration or even avoidance. Some parents might shy away from helping with art projects or feel hesitant to comment on drawings or crafts, worried they’ll say the wrong thing. But the desire to be involved, to participate fully, remains strong.

Understanding Colourblindness in Everyday Life
Colourblindness doesn’t just affect art—it can impact everything from reading coloured charts to recognising warning signs or picking out clothes. But in parenting, where so much communication is non-verbal and visual, the challenges can feel particularly personal.

The good news is, tools and technology are evolving to help bridge the gap.

How iRo Lenses Can Help
One such advancement is iRo Lenses—specially designed lenses that enhance colour perception by filtering specific wavelengths of light. For colourblind parents, wearing iRo Lenses can improve the ability to distinguish between commonly confused colours, bringing clarity to previously muddled visuals.

When it comes to your child’s artwork, iRo Lenses can help you see the colours more accurately—so the rainbow really does look like a rainbow, and the red heart shines through. It’s not just about colour correction—it’s about connection. And for many families, that makes all the difference.

What is Colourblindness?
Colourblindness (or colour vision deficiency) is often inherited and affects how people perceive certain colours. The most common form is red-green colourblindness, which doesn’t mean people see only in black and white—it simply means they have difficulty distinguishing between shades of red, green, brown and sometimes even orange and grey. This can have a surprisingly large impact in settings like supermarkets, where colour is used constantly as a visual cue.

Trouble in the Fruit and Veg Aisle
One of the most obvious challenges is selecting fresh produce. Shoppers often rely on colour to tell whether fruit is ripe, overripe or unripe. But for someone who can’t tell the difference between green and red, working out whether a tomato is ready to eat—or still needs time to ripen—is tricky. Bananas, avocados, mangoes and melons all present similar challenges. Without being able to judge colour changes accurately, colourblind shoppers are more likely to end up with overripe or underripe produce.

To compensate, some rely more heavily on touch, smell or labelled packaging (if available), but this isn’t always reliable, especially in bulk produce areas.

Packaging and Labels
Marketing relies heavily on colour. Whether it’s red for “hot” or “spicy”, green for “healthy” or “plant-based”, or colour-coded product ranges, these cues can easily be missed by someone with a colour vision deficiency. In some cases, important information like allergen warnings or ingredient highlights may be colour-coded rather than clearly written, which can lead to confusion or accidental purchases.

For example, a colour-coded nutrition label with green for “low fat”, amber for “medium”, and red for “high” might not be useful to someone who struggles to distinguish those colours.

Price Tags and Specials
Supermarkets often use colour to highlight discounts, multi-buy offers or clearance items. But if those signs rely on red or green backgrounds without accompanying text or symbols, they may go unnoticed by colourblind shoppers. This can lead to missed savings or frustration when trying to compare prices quickly.

What Can Be Done?
The good news is that small changes in supermarket design can make a big difference. Clear text, high contrast labels, symbols alongside colours, and better lighting can all help. Some colourblind shoppers also use smartphone apps that help identify colours in real time by using the phone’s camera.

A More Inclusive Shopping Experience
Colourblindness might be invisible, but its impact on daily life is very real. Recognising the challenges it presents—and finding ways to make shopping environments more accessible—helps ensure that everyone, regardless of how they see the world, can navigate the supermarket with confidence.

How iRo Lenses Can Help
For those living with colour vision deficiency, tools like iRo Lenses can make a meaningful difference. These specially designed lenses enhance colour perception by filtering specific wavelengths of light, helping users better distinguish between commonly confused colours—such as reds and greens. For everyday tasks like grocery shopping, iRo Lenses can make it easier to identify ripe produce, read labels, and spot colour-coded offers with greater confidence. By improving clarity and contrast, they offer practical support for navigating the world more easily—starting with something as simple (and essential) as the weekly shop.

The retina, located at the back of the eye, is a complex structure that processes light and colour. It contains two types of photoreceptor cells: rods and cones. Rods are responsible for detecting light and dark, allowing us to see in low-light conditions, while cones are responsible for colour vision. There are three types of cones, each sensitive to a specific wavelength of light: red (long wavelengths), green (medium wavelengths), and blue (short wavelengths). Together, these cones allow the brain to mix and match signals, creating the vibrant range of colours we see.

In individuals with colour blindness, the issue lies in these cones. The most common types of colour blindness – red-green and blue-yellow deficiencies – occur when one or more cone types are absent, malfunctioning, or shifted in sensitivity. For example, in red-green colour blindness, the red and green cones overlap significantly in their response to light, causing these colours to appear indistinguishable or muted.

This difference in cone functionality can be caused by genetic factors. Colour blindness is often inherited in an X-linked recessive pattern, which is why it is more common in men (who have only one X chromosome). However, colour blindness can also arise from damage to the retina, optic nerve, or brain, as well as from certain diseases or medications.

To better understand what colour blindness looks like, consider how red and green might blend into a single hue, making tasks like identifying ripe fruit or reading traffic lights challenging. Similarly, blue-yellow colour blindness can make it difficult to distinguish between shades of blue and green or yellow and red. For those with total colour blindness (achromatopsia), the world appears in shades of grey, as their cones cannot detect colour at all.

Advances in technology and research have helped demystify the condition. Tools like colour blindness simulations allow people with typical vision to experience how the world appears to those with colour deficiencies. Additionally, innovations like iRo lenses offer colour blind individuals the chance to enhance their perception by filtering and amplifying certain wavelengths of light.

Understanding the anatomical basis of colour blindness fosters greater empathy and awareness. It’s not merely a quirk of perception but a structural variation that shapes how some people interact with the world. By embracing education and technology, we can bridge the gap with iRo Lenses between experiences and ensure that those with colour blindness feel understood and supported.
