As a parent, it’s natural to feel concerned when you notice your child’s glasses prescription getting stronger every year. It goes without saying that you want to do everything you can to protect their vision for the future. That’s why it’s not surprising that many parents ask us if we can reverse their child’s myopia.

While there is currently no cure for myopia, its progression can be effectively controlled with modern myopia management treatments. Our dedicated eye doctors can help you make informed decisions for your child’s eye health and protect their future vision.

Why Myopia Can’t Reversed

Myopia Involves Structural Eye Changes

Myopia, or nearsightedness, occurs when the eyeball grows slightly too long from front to back. This causes light to focus in front of the retina (a tissue at the back of the eye) instead of directly on it, making distant objects look blurry. Because this is a physical change in the eye’s structure, it cannot be reversed.

Control Is the Goal

The goal of modern pediatric eye care is to slow or stop the progression of myopia. This approach is called myopia control. By managing how fast your child’s prescription changes, we can help reduce the rate at which their nearsightedness gets worse.

How Myopia Is Managed

Management often starts with corrective lenses like glasses or contact lenses to provide clear vision. We can then create a customized plan with proactive treatments to slow the eye’s elongation. These methods are designed to help protect your child’s eye health as they grow.

Signs Your Child May Have Myopia

Sometimes children don’t realize their vision is blurry because it changes so gradually. It’s helpful to watch for subtle signs that they may be struggling to see clearly. If you notice any of these behaviours, it may be time for a comprehensive eye exam.

  • Squinting to see the television or the board at school
  • Moving closer to screens or holding books close to their face
  • Rubbing their eyes frequently
  • Complaining about headaches or tired eyes
  • A sudden drop in grades or difficulty concentrating on schoolwork

Effective Myopia Control Treatments

After a thorough eye exam, we can discuss the most suitable options for your child’s needs and lifestyle. As always, our goal is to find an approach that works best for your family. Here are some of the most common options.

Specialty Contact Lenses

These contacts correct blurry distance vision while also helping to slow down elongation of the eye over time.

Atropine Eye Drops

A low-dose medicated eye drop used once a day can be an effective way to slow myopia progression. These drops are simple to use and are a great option for many children. Your child would still also wear their regular glasses or contacts to see clearly.

Myopia Control Glasses

For children who prefer to wear glasses, there are now lenses designed for myopia control. These lenses work by reducing signals that encourage the eyeball to grow longer.

Lifestyle Habits & Myopia Progression

Daily routines and habits also play a part in your child’s eye health. Incorporating a few simple changes into your family’s day can support their vision. These habits work alongside professional treatments to help manage nearsightedness.

The Importance of Outdoor Time

Spending time outside in natural daylight is beneficial for your child’s eyes. Aim for at least 90 minutes of outdoor play each day. This is one of the most effective ways to help slow down myopia’s progression.

Screen Time & Its Impact on Vision

Encourage your child to take regular breaks from digital screens and other close-up activities. While the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds) can still be helpful, current research is shifting toward a more effective approach: after every 15 minutes of near work, take a 5-minute break.

These slightly longer breaks give the eyes more time to relax and may help slow down the signals that encourage the eyeball to grow longer—a key factor in the progression of myopia (nearsightedness).

Create Good Read & Study Habits

Ensure your child has proper lighting when reading or doing homework to avoid eye strain. Remind them to hold books and devices at a comfortable distance, about an arm’s length away. These small adjustments can make a big difference over time.

What to Expect As Your Child Grows

Myopia often begins during the school years and can continue to progress into early adulthood. Knowing what to expect can help you stay on top of your child’s changing vision needs. Consistent care is key to long-term success.

The Ideal Age for Intervention

Myopia control is most effective when it begins as soon as nearsightedness is identified. This is often between the ages of 6 and 12, a critical period of growth for the eyes. Early intervention gives us the best opportunity to manage the condition.

At What Age Does Myopia Usually Stop Progress?

In most cases, myopia progression slows down and stabilizes in the late teens or early twenties. The goal of early management is to keep the final prescription as low as possible. This approach supports clearer vision and healthier eyes for a lifetime.

The Goal of Long-Term Eye Health

By managing myopia progression today, you are investing in your child’s future eye health. Slowing the progression helps lower their risk of developing serious eye conditions later in life. These include retinal detachment, glaucoma, and myopic maculopathy, which are significant risks associated with high myopia.

While we can’t reverse nearsightedness, there are tools available to manage it effectively. At Eyelab Doctors of Optometry, we are here to help your family navigate this journey. Contact us to request an appointment.

Eye infections can be stressful for parents, especially when your child complains of eye pain or irritation. Two of the most common culprits for irritated eyes are pink eye (conjunctivitis) and a stye (hordeolum). Both can cause redness, swelling, and discomfort, but they’re actually very different conditions.

When it comes to kids, spotting the differences between pink eye and a stye early helps you get the right treatment quickly. Pink eye usually causes widespread redness and discharge in the eye itself, while a stye appears as a painful bump on the eyelid.

Let’s have a look at what pink eye and styes are, how to tell them apart, whether they’re contagious, and when to see an optometrist.

Understanding Pink Eye

Pink eye, or conjunctivitis, is an inflammation of the conjunctiva—the clear tissue that lines the inside of the eyelids and covers the white of the eye. In children, it often looks alarming because the whole eye may appear red or bloodshot. Pink eye can cause itchiness, tearing, and sometimes a sticky discharge that makes the eyelids crust together after sleep.

How do you know if your child has pink eye? The answer depends on the cause. Pink eye can be triggered by:

  • Viruses (like adenovirus, which often spreads with colds)
  • Bacteria (such as Streptococcus or Staphylococcus)
  • Allergens (like pollen, dust, or pet dander)
  • Irritants (such as chlorine from pools, smoke, or harsh chemicals)

Viral and bacterial pink eye are contagious, especially in school or daycare settings. Allergic and irritant types are not. While most cases of pink eye are mild, bacterial pink eye may require antibiotics.

Common Symptoms of Pink Eye

  • Redness across the white of the eye
  • Watery or mucous discharge (clear with viral, thick and yellow-green with bacterial)
  • Itchy or gritty sensation
  • Crusty eyelids in the morning
  • Sensitivity to light
  • Swollen eyelids

Understanding a Stye

A stye is a small, painful lump on the eyelid, similar to a pimple. It forms when an oil gland in the eyelid becomes blocked and infected, most often by Staphylococcus bacteria. Unlike pink eye, a stye does not spread across the eye’s surface—it stays localised to the eyelid.

Unlike pink eye, styes are not typically contagious. However, the bacteria that cause styes can be spread through poor eyelid hygiene, so it’s important to teach kids not to rub their eyes.

Common Symptoms of a Stye

  • A red, swollen bump on the eyelid (external or internal)
  • Localised tenderness or pain
  • Swelling in the eyelid, sometimes with a visible white spot
  • Tearing or watery eyes
  • Crusting along the lash line

Most styes heal on their own within a week. Warm compresses applied several times daily can help the stye drain naturally.

Stye vs Pink Eye: Key Differences

While both conditions can cause redness and irritation, there are several clear differences:

  • Location
    • Pink Eye: Affects the conjunctiva, covering the eyeball.
    • Stye: Appears as a lump on the eyelid margin.
  • Appearance
    • Pink Eye: The entire white of the eye looks red.
    • Stye: A single, red, pimple-like bump on the eyelid.
  • Discharge
    • Pink Eye: Watery or pus-like discharge.
    • Stye: Minimal discharge, usually only crusting.
  • Contagion
    • Pink Eye: Viral and bacterial forms are highly contagious.
    • Stye: Generally not contagious.

How Do You Get Pink Eye?

Children are especially prone to pink eye, which spreads easily in shared spaces. Kids can catch it by:

  • Touching their eyes after contact with contaminated surfaces (toys, doorknobs, desks)
  • Sharing towels, washcloths, or pillowcases
  • Exposure to someone already infected
  • Swimming in pools without proper chlorine balance

Good handwashing habits and teaching children not to touch their faces are key ways to lower risk.

Diagnosis & Treatment

Treating Pink Eye

  • Viral pink eye: Usually clears on its own in 1–2 weeks. Cool compresses and lubricating eye drops can ease discomfort.
  • Bacterial pink eye: May require antibiotic eye drops or ointments. Keeping the eyes clean and avoiding contact with others helps prevent the spread.
  • Allergic pink eye: Treated with antihistamine or anti-inflammatory drops. Reducing allergen exposure (keeping windows closed during pollen season, washing bedding often) is helpful.
  • Irritant pink eye: Apply preservative-free artificial tears and avoiding further irritants is usually enough.

Treating a Stye

  • Apply warm compresses for 10–15 minutes, several times a day.
  • Do not squeeze or pop the stye—it can worsen the infection.
  • Keep eyelids clean using medicated lid wipes or hypochlorous acid (HOCI) sprays.
  • Avoid eye makeup until healed.
  • In stubborn cases, an optometrist may prescribe antibiotic ointment.

Prevention Tips

Both pink eye and styes can often be avoided with good hygiene:

  • Wash your hands regularly with soap and water
  • Avoid touching or rubbing the eyes
  • Do not share towels, bedding, or makeup
  • Keep glasses, contact lenses, and cases clean
  • Encourage children to practice good eyelid hygiene if they’re prone to styes

When To See an Optometrist

If your child has severe redness, pain, swelling, light sensitivity or vision changes, or if their symptoms don’t improve within a few days, it’s time to see an eye care professional. Proper diagnosis ensures the right treatment and prevents complications.

Understanding the difference between a stye and pink eye can save you time, reduce worry, and help you get the right care for your child. If you’re ever unsure, an eye exam is the best way to confirm what’s going on.

Ensuring your child’s eye health is essential for their well-being and development. Clear vision is pivotal in every aspect of their life, from academic success to extracurricular activities.

Your child should see their eye doctor for the first time at around 6 months. During your child’s eye exam, you can expect the following:

The exact process may vary depending on your child’s age and needs. But this gives you an overall picture of what to expect.

What Is a Children’s Eye Exam?

A child’s eye exam checks much more than whether or not your child needs glasses. It’s a thorough evaluation of their vision and eye health, ensuring that their eyes function correctly as a team and are free of abnormalities or diseases.

Children’s eye exams assess several key factors, including:

  • Visual acuity: Clarity of vision at varying distances
  • Eye alignment: Ensures both eyes coordinate correctly for comfortable, clear vision
  • Eye health: Evaluations to rule out infections, injuries, or underlying conditions related to eye health
  • Focus and tracking: Determines how well your child’s eyes focus on up-close objects and track moving objects

Most eye doctors personalize these exams to meet children’s needs. They often use child-friendly language, interactive techniques, and age-appropriate tools to make the process comfortable and engaging.

How Often Should Your Child Get an Eye Exam?

According to the Canadian Association of Optometrists, the recommended frequency for pediatric eye exams depends on your child’s age and medical history. Here’s a guideline to follow:

  • Infants (Between 6 and 9 months): The first comprehensive eye exam should happen in this window to ensure your baby’s sight develops properly
  • Toddlers (2 to 5): A second eye exam before starting school can help detect and address vision issues early on
  • School-aged children (6 to 19 years): Annual eye exams are essential during these years, as your child’s eyes may change due to growth or prolonged screen use

Proactive and regular eye exams help identify issues before they become roadblocks to your child’s learning and overall development. It’s worth noting that many provincial health plans in Canada cover children’s eye exams fully or partially, making it even easier to prioritize their visual health.

What to Expect at Your Child’s Eye Exam

First-time visits to the optometrist can feel daunting for kids and parents alike. But rest assured, the process is designed to be engaging, comfortable, and thorough.

Discussion of Medical & Developmental History

Your child’s visit typically begins with a conversation between you and their optometrist. We’ll ask about your child’s health history, noticeable vision problems, family history of eye-related conditions, and any concerns you may have.

Vision Tests

We’ll assess your child’s ability to see clearly at various distances using age-appropriate tools. This might involve identifying pictures or shapes instead of reading a standard eye chart for younger children.

Eye Health Examination

We evaluate the overall health of your child’s eyes using various pieces of specialized equipment. This step looks for infections, injuries, or early signs of diseases like cataracts that are present.

Functional Eye Tests

These tests check how well your child’s eyes work together. We may assess alignment, depth perception, and focusing abilities.

Consultation & Recommendations

If an issue is detected, we’ll provide potential solutions, such as glasses or further treatments. You’ll also typically receive advice on how to support your child’s visual health at home.

Common Eye Conditions in Children

Children’s eyes can be susceptible to a range of different conditions. Early detection is key to managing these effectively.

Astigmatism

Astigmatism occurs when the cornea or lens is irregularly shaped, causing blurry or distorted vision. Kids with astigmatism might struggle to see both near and far objects clearly. Glasses or contact lenses can help correct this issue, allowing for clearer vision.

Myopia (Nearsightedness)

Myopia is when objects up close are clear, but distant objects appear blurry. It often progresses during school years, especially with frequent screen use. Tailored treatments like orthokeratology lenses or myopia control therapies can slow progression of the condition.

Crossed Eyes (Strabismus)

Strabismus is a condition in which the eyes don’t align properly, resulting in one eye pointing in a different direction than the other. If left untreated, this can cause depth perception issues and may eventually lead to lazy eye. Treatment might include vision therapy, glasses, or, in some cases, surgery.

Lazy Eye (Amblyopia)

Amblyopia occurs when one eye develops weaker vision than the other. Often stemming from strabismus or uncorrected refractive errors, it can lead to long-term visual impairments if untreated. Early interventions like corrective lenses or vision therapy usually yield successful outcomes.

Pink eye, or conjunctivitis, is one of the most common and misunderstood eye conditions. Its hallmark symptoms—redness, itchiness, and watery discharge—can cause alarm, especially in parents worried about their children or individuals dealing with recurring eye irritations.

However, not every red or itchy eye is caused by pink eye, leading to frequent misdiagnoses, including dry eye syndrome, eye strain, blepharitis, and contact lens irritation. Identifying the root cause of your symptoms could save you unnecessary treatments and help you find the right solution.

What is Pink Eye?

Pink eye, medically referred to as conjunctivitis, is an inflammation of the conjunctiva, the thin, transparent tissue that lines the eyelid and covers the white part of the eye (sclera). This condition can arise from various causes, including bacterial or viral infections, allergens, or irritants, and symptoms often overlap among these different varieties.

The three main types of pink eye are:

  • Viral conjunctivitis: Often associated with cold-like symptoms and watery discharge.
  • Bacterial conjunctivitis: Accompanied by thick yellow or green discharge and increased swelling.  
  • Allergic conjunctivitis: Triggered by allergens like pollen, dust, or pet dander.  

While viral and bacterial conjunctivitis are contagious, allergic conjunctivitis is not. Understanding these differences can help manage symptoms and reduce unnecessary anxiety.

Allergic Conjunctivitis

Allergic conjunctivitis is a frequent pink eye imitator, often mistaken for its bacterial or viral counterparts. Instead of infections, allergic conjunctivitis is triggered by environmental allergens.

Common symptoms of allergic conjunctivitis include:

  • Intense itchiness in both eyes.
  • Redness and watery discharge.
  • Additional allergy symptoms like sneezing or nasal congestion.  

One distinguishing clue is that allergic conjunctivitis typically occurs in both eyes simultaneously and may coincide with seasonal allergy peaks.

What is Commonly Misdiagnosed as Pink Eye?

Certain eye conditions mimic the redness and discomfort of pink eye but have entirely different causes. Proper diagnosis can prevent ineffective treatments and address the underlying issue at its source.

1. Dry Eye Syndrome

Dry eye syndrome occurs when your eyes fail to produce enough tears or the correct quality of tears to keep them hydrated. People with this condition often mistake their chronic dryness for recurrent pink eye.

Symptoms of dry eye that mimic pink eye:

  • Persistent redness.  
  • Burning or stinging sensation.  
  • Sensitivity to light and blurred vision.  

Unlike pink eye, dry eye syndrome does not cause discharge. Its root cause may be environmental factors (air conditioning), prolonged screen time, or conditions like Sjögren’s syndrome.

2. Eye Strain or Fatigue

Eye strain is becoming increasingly common in a world dominated by screens. Spending long hours staring at digital devices without breaks can cause eye strain, leading to redness and discomfort that is often mistaken for pink eye.

Symptoms of eye strain include:

  • Eye redness from overuse or irritation.  
  • Dry, tired eyes that may feel itchy or sore.  
  • Headaches and difficulty focusing.  

Notably, eye strain lacks the discharge and contagiousness associated with bacterial or viral conjunctivitis, making rest and adjusting screen habits the most effective remedies.

3. Blepharitis

Blepharitis is a chronic condition involving inflammation of the eyelids, often due to bacteria or clogged oil glands. Its symptoms can closely resemble pink eye.

Symptoms of blepharitis that mimic pink eye:

  • Red and itchy eyelids.  
  • Crusting around the eyelashes, particularly upon waking.   
  • Watery eyes and a burning sensation.  

Though not contagious, blepharitis can progress to severe discomfort if left untreated and requires specific interventions, such as maintaining eyelid hygiene or using medicated eyelid wipes.

4. Contact Lens Irritation

Contact lens wearers often experience redness and irritation, which can lead them to fear they’ve developed pink eye. However, rather than an infection, these symptoms are frequently linked to overuse, improper cleaning solutions, or lens-related allergies.

Symptoms of contact lens irritation include:

  • Eye redness after extended lens wear.  
  • Irritation or a foreign body sensation in the eye.  
  • Dry, watery eyes or blurry vision that resolves after lens removal.  

Switching to daily lenses, cleaning cases properly, or using specialized lens-friendly drops often resolves these problems quickly.

Prevention & Treatment for Pink Eye

Whether you’re dealing with actual pink eye or a commonly misdiagnosed condition, taking precautionary measures and seeking appropriate treatment could spare you unnecessary discomfort.

Prevention Tips:

  • Practice Good Hygiene: Wash your hands frequently, especially before touching your eyes. Avoid sharing towels, washcloths, or pillows.  
  • Allergen Avoidance: Minimizing exposure to triggers like pollen or pet dander can prevent allergic conjunctivitis for allergy sufferers.  
  • Reduce Screen Time: Regular breaks using the 20-20-20 rule (look 20 feet away every 20 minutes for 20 seconds) can ease digital eye strain.  
  • Maintain Contact Lens Hygiene: Follow the cleaning instructions for your lenses, and always replace them as recommended.  

Treatments for Pink Eye & Its Look-Alikes:

  • For bacterial conjunctivitis, antibiotic drops can usually clear up symptoms.  
  • Viral conjunctivitis doesn’t require medication and instead heals on its own in one to two weeks.  
  • Allergic conjunctivitis is best managed with antihistamines or allergy-eye drops.  
  • For dry eye, artificial tears and environmental changes often bring relief.  
  • Conditions like blepharitis or contact lens irritation may require specialty treatments or specific eye care regimens.  

Always consult with an eye care professional for persistent or severe symptoms. Proper diagnosis ensures the best treatment plan.

Take Control of Your Eye Health

Not every red eye indicates pink eye. Dry eye syndrome, eye strain, blepharitis, and contact lens irritation can all mimic the symptoms, adding to unnecessary confusion and distress. Identifying the root cause is key to seeking the right solution and effectively relieving symptoms.

At Eyelab Doctors of Optometry, we believe in investing early into eye health to save yourself from long-term complications and discomfort. Contact us today to schedule an appointment to help with your symptoms and find relief.

Vision problems in children can often go unnoticed, as kids may not realize their eyesight is impaired. Recognizing the signs that your child might need glasses and scheduling regular eye exams are essential for maintaining their visual health and academic success. Early detection can make a significant difference in their daily life and development.

Regular eye examinations are key to identifying refractive errors and ensuring your child’s vision is clear. At an exam, your optometrist will assess their overall eye health using modern technology to determine if glasses are a suitable option for your child.

Common Signs Your Child Might Need Glasses

Ensure to look out for these typical signs that your child may require glasses to help with daily life:

Squinting to See Clearly

If your child frequently squints when looking at objects far away or close up, it could indicate a refractive error such as myopia or hyperopia. Squinting helps temporarily sharpen their focus but may lead to strain over time.

Frequent Headaches

Headaches, particularly after school or homework, can be a sign of uncorrected vision issues. Eye strain from trying to focus on words or objects can cause persistent discomfort.

Sitting Too Close to Screens

Children with myopia often move closer to TVs, tablets, or books to see clearly. This behaviour can indicate that their distance vision is impaired.

Eye Rubbing or Tired Eyes

Excessive eye rubbing or complaining of tired eyes may signal that your child is struggling to focus. This can be linked to undiagnosed vision problems.

Avoiding Reading or Schoolwork

Reluctance to read or complete assignments may stem from difficulty seeing the words on the page. Correcting their vision can make these tasks easier and more enjoyable.

Trouble in the Classroom

If your child is having difficulty seeing the board or focusing during lessons, it could affect their academic performance. Glasses can help them participate fully in school activities.

Why Regular Eye Exams Are Essential for Children

Diagnosing conditions like myopia or hyperopia early is crucial. The sooner these eye issues are detected and treated, the quicker your child can experience improved vision and comfort. Many vision problems develop during childhood, making early detection vital to prevent progression.

It’s recommended that children have their first eye exam at six months old, a follow-up at three years, and annual check-ups once they start school. Regular exams help monitor their vision and address any changes promptly.

Frequency of Children’s Eye Exams in British Columbia

The British Columbia Association of Optometrists guidelines suggest the first eye exam to be done at 6 months of age followed by a second exam before kindergarten. However, at Eyelab, we recommend a slightly different timeline to monitor the child’s vision development more accurately.

At Eyelab, we recommend the following schedule for children’s eye exams:

  • First exam: At 6 months old
  • Annual exams: Every year starting at the age of 1

Early and regular exams help establish a baseline for their vision and eye health, supporting proper development and milestone achievement.

How We Perform an Eye Exam on a 6-Month-Old

As parents, it is obvious to wonder how eye exams are conducted on 6-month old babies who cannot yet communicate. Fortunately, optometrists don’t need verbal responses to assess a child’s vision.

The baby only needs to be able to follow visual targets. Optometrists can shine lights to look into their eyes and check their refractive status (i.e. their prescription), check for lazy eye and also ocular health. To make things easy, we recommend scheduling your baby’s eye exam when they are well-rested, ideally between naps, to ensure they are comfortable and cooperative during the appointment.

How Glasses Help Children

  • Improved academic performance: Clear vision allows children to read, write, and participate in classroom activities without unnecessary strain.
  • Enhanced confidence: Seeing clearly can improve your child’s ability to engage in social interactions and sports, boosting their confidence.
  • Addressing vision problems early: Prescription glasses can correct refractive errors, helping your child see clearly and avoid long-term complications.

When to See an Eye Doctor at The Eye Lab

If your child is exhibiting any of the signs listed above, it’s important to schedule an eye exam as soon as possible. Early intervention can ensure that vision problems don’t impact their learning, development, or quality of life.

At Eye Lab in Vancouver, BC, our experienced team provides comprehensive eye examinations tailored to children’s needs. We use modern technology to assess their vision and identify any potential issues. Whether your child requires glasses or myopia control, we’re here to help them achieve clear, comfortable vision.

Navigating the world through the eyes of a child is an awe-inspiring experience. Colours play a pivotal role in their development—teaching them to categorize, express themselves, and form vital connections to the environment. However, for many children with colour vision deficiency (CVD), interacting with colour looks a little different.

Colour vision deficiency (CVD) affects how a child sees and differentiates colours, which can have notable impacts on their daily life, learning, and time spent with friends. Your optometrist has the technology to diagnose and manage this lifelong condition.

What Is Colour Vision Deficiency (CVD)?

Colour vision deficiency, frequently referred to as colour blindness, is a condition where the ability to perceive colours accurately is impaired. While many people use the term colour blindness, most people with CVD are not totally blind to colour but have difficulty distinguishing particular hues.

CVD comes in a few different types, including:

  • Red-Green Deficiency: The most common type of CVD where people are unable to perceive red wavelengths (protanope) or green wavelengths (deuteranope).
  • Blue-Yellow Deficiency: Less common than red-green deficiency, blue-yellow deficiency (trianope) generally occurs after optical nerve damage. People with this type may confuse greens with blues and oranges with reds.
  • Complete Colour Blindness: Also known as achromatopsia, this type of color blindness is exceedingly rare. People with this condition cannot distinguish colors at all and instead see the world in shades of grey.

Colour deficiency is more common in males, affecting 1 in 12 men. CVD is often inherited and usually results from abnormalities in the cone cells within the retina, the layer of light-reactive cells at the back of the eye. These cones are responsible for detecting colour, and when one or more types are missing or functioning abnormally, CVD occurs.

Signs & Symptoms in Children

Detecting CVD in children can be tricky because children naturally adapt to how they see the world and might not realize that something is amiss with their vision. In fact, children with CVD often don’t complain of vision issues because they don’t even realize that anything is wrong.

Nonetheless, there are tell-tale signs that parents can watch for. Possible indicators of CVD include:

  • Confusion when learning or naming colours (e.g., calling green “brown”).
  • Struggles to match or group items based on colour.
  • Difficulty identifying ripe fruits or cooked food by their colour.
  • Frequent errors in colour-based tasks, like misidentifying red crayons as brown.
  • A preference for tasks that don’t require colour identification.

How CVD Impacts Learning & Development

Much of the way we have structured society is based on colour. That’s why, for children, CVD extends beyond vision; it influences everyday tasks and developmental milestones.

Education materials, especially in early learning stages, heavily rely on colour coding (e.g., charts, maps, and patterns). A child with CVD might struggle to follow lessons tied to these resources. Misinterpreting colours can also lead to misunderstandings in social settings, affecting how children interact with peers or perform group tasks.

We often label dangerous objects with bright red or yellow signs This makes tasks like safely interpreting traffic lights or warnings on labels are also more difficult for people with CVD.

However, with the right strategies and support, children with CVD can thrive, even in a colour-reliant world.

How Optometrists Diagnose Colour Vision Deficiency

Diagnosing colour vision deficiency starts with a visit to an optometrist. This visit will involve specialized but typically non-invasive tests that are designed for even young children. Since CVD is often hereditary, the optometrist will begin by asking about your medical and family history. Then, they’ll use a few simple tests to figure out what type of colour vision deficiency your child might have and how severe it is. Some of the tests involved include:

  • Colour plate test: The most common test involves looking at colour plates with numbers or patterns hidden in the design. Those who have CVD are unable to perceive these numbers or patterns. This test is great for spotting red-green colorblindness.
  • Hue test: The hue test helps check how well children can tell the difference between similar colours. Children will be given blocks of different colours and must arrange them in the right order based on their shades. Mistakes in ordering can indicate the kind of colour vision issues a child might have and how severe those issues may be.
  • Anomaloscope test: During this test, your child will look through an eyepiece at 2 lights. These lights have different levels of brightness. The optometrist will adjust the lights using knobs and until your child perceives the lights as matching. If they’re unable to match the lights, this could mean they have a colour vision deficiency.

Your optometrist can explain the results and help your child find tools or strategies to navigate the world with confidence. Standard eye exams often don’t include tests for colour vision, which means parents who suspect CVD should request one specifically.

Coping Strategies & Support for CVD

There’s no cure for colour vision deficiency, but thoughtful adjustments and tools can help minimize its impact. Parents, teachers, and caregivers all play a pivotal role in creating an accommodating space for children.

Here are some tips for helping children with CVD:

  • Use labels instead of colour: Use labels or patterns to differentiate items instead of relying only on colours (e.g., marking folders with symbols rather than colours).
  • Teach practical workarounds: Help your child memorize the order of colour-coded systems, like the sequence of traffic lights (for example, top-to-bottom rather than red-yellow-green).
  • Encourage accessible learning environments: Communicate with teachers and ask them to use non-colour-dependent materials in class.
  • Leverage technology where possible: Apps and filters, like EnChroma glasses or digital tools, can help improve colour recognition or adjust colours on screens. Even many video games have colour-accessible options these days!
  • Encourage open conversation: Regularly discuss your child’s feelings and experiences regarding their vision, encouraging them to share challenges they may be facing.

When the right support is in place, CVD doesn’t have to impact a child’s success or confidence.

Growing Up With Colour Vision Deficiency

Children with colour vision deficiency (CVD) may face some unique challenges.

While certain careers that rely heavily on colour perception—like being a police officer, airline pilot, or working in fashion or electrical fields—might be more difficult, there are countless other opportunities where CVD isn’t a barrier. Jobs like doctors, lawyers, writers, engineers, and many more are completely accessible.

As a parent, focus on your child’s strengths and interests so they can be as confident in themselves as you are in them.

Can People with CVD Drive?

One common question from parents is whether kids with CVD can eventually learn to drive. The good news is that most can! Traffic lights are normally designed with both colour and position cues—red at the top, yellow in the middle, and green at the bottom (or left to right in horizontal layouts).

As long as they can tell the difference between the traffic lights and pass the driving test, kids with CVD can become responsible drivers.

While it is untrue that reading in the dark will permanently damage your eyes it can cause shorter term issues. You may have to strain harder which can lead to headaches, irritated eyes, general eye fatigue. If this is coupled with other existing issues you may also experience blurry vision or even double vision temporarily. The extra strain and need to focus may also prevent you from blinking as often, leading to dry eye symptoms.

If I’m careful with cleaning, can I wear my dailies for more than 1 day?

Daily disposables are thinner and are made of a material that is not made to resist bacteria and buildup. So, if you try to clean or disinfect these thin lenses you may actually create breaks instead, further increasing infection risk. Using a compatible brand of soft contact lens rewetting drops to hydrate your daily disposables for comfort is acceptable.

What happens if I wear dailies for more than 1 day?

Wearing daily disposable contact lenses more than once puts you at risk for discomfort, dryness, corneal ulceration/scarring, and eye infections.

Differences between Dailies, Bi-weeklies, and Monthlies

Dailies are worn only for one day and discarded when you remove them, these are typically very thin and have a high water content. Natural deposits from your eyes build up easily on their surface, and they cannot be reused. This could mean more convenience but also, depending on how often you replace them, more costly.

Monthly or bi-weekly contact lenses are thicker than daily disposables. The thicker composition makes them more durable and long-lasting, and they are usually more resistant to drying out. However, they must be disinfected regularly in order to ensure healthy wearing.

Having an annual eye exam is a great way to not only take care of your eyes but your overall health as well. Eye exams can detect early signs of conditions such as diabetes and high blood pressure. Here are some tips to help you make the most of your next visit!

What to think about:

  • Have I noticed any eye problems such as blurry vision, flashes of light, floaters, redness, or double vision?
  • Are my daily activities being affected by my vision?
  • How do I take care of my contact lenses or glasses
  • Have I had any surgeries or injuries in my eyes that I could let the doctor know about?
  • Any family history of eye conditions such as glaucoma?

What to bring:

  • Your current glasses or contact lenses even if you have multiple pairs for different tasks
  • A list of your medications/supplements you are taking
  • Have someone who can drive you home or a method of transportation ready for if you have your eyes dilated. This happens often in yearly eye exams and can make you sensitive to light and have blurry near vision (~4-6 hours)
  • Vision and health insurance information

Questions to ask:

  • Differences between contacts and glasses for you and how this compares to surgery options as well?
  • If anything has changed in my ocular health since the last visit?
  • What any symptoms you may have mean and what you can do to prevent them from getting worse or resolve?
  • When should I return for my next visit?

Why do I need to be fitted for contact lenses? Did you know your glasses prescription is different from your contact lens prescription? When an optometrist fits you for contact lenses, they are ensuring several things:

  • Your eye is healthy enough to be wearing contact lenses. Conditions such as dry eyes and allergic conjunctivitis need to be treated before you can wear contact lenses. Eye conditions such as corneal scars, dystrophies, and/or irregular surfaces may require a fitting with specialty lenses.
  • The contact lens is the right type for your life style. Based on your occupation, extracurricular activities, and other needs, we can help you determine whether dailies, bi-weekly, or monthly contact lenses will meet your needs.
  • Finding a comfortable fit with good vision. We take measurements of your eyes to fit you in a comfortable lens. Many companies make contact lenses, and each have a set of parameters they work with. We can check if a lens is too tight or too loose on your eyes, how the contact lens moves when you blink, and whether it is centered on your eye. We also ensure each eye sees well both at a distance and near.

In addition, we first train new contact lens wearers on how to safety insert and remove contact lenses. We will go over the cleaning process, to ensure that lenses are handled safely because any buildup of proteins and debris on the lenses can cause damage to the cornea.
