Colorimetry Glasses for Relieving Visual Stress & Dyslexia

Microprism Optics has had much success with colorimetry glasses (also known as dyslexia glasses) and coloured overlays. Many of our patients have experienced a substantial improvement in their comfort and speed with reading and comprehension.

All tinted reading glasses and precision tinted lenses prescribed by our optometrist following a colorimetry assessment are tinted at our special purpose lab, along with any refractive prescription when necessary.

What Are They?

Colorimetry glasses are prescribed coloured glasses or coloured overlays that can ease any perceived visual distortions the patient experiences. This special type of reading glasses removes the visual stress someone with dyslexia experiences in order to improve their ability to read.

How Do They Help with Visual Stress and Dyslexia?

Certain reading difficulties have been associated with dyslexia or visual stress, which is also known as Irlen Syndrome. One common treatment an optometrist may recommend for relieving dyslexia and visual stress experienced when reading is prescribing the patient either tinted reading glasses that include precision tinted lenses or coloured overlays. Please note that visual stress is a different condition to dyslexia, although a patient can experience them simultaneously.

Signs of Visual Stress

  • Words on a page move, wobble, overlap or are blurred
  • Shapes appear on the page
  • The print hurts the eyes
  • Rubbing the eyes while reading
  • The white on the page is very bright
  • The reader’s eyes jump between lines
  • The reader finds it hard to keep track of what they’re reading

Test and Assessment

A colorimetry test will determine what colour tinted reading glasses have to be prescribed. A lightbox containing coloured filters is used to find the specific colour and density that should be used for the precision tinted lenses in the tinted glasses. The assessment of a patient’s visual stress usually comprises of pattern glare tests, an overlay screening, and using an intuitive colorimeter.

How Behavioural Optometry Helps

  • Stops vision and eye issues from developing
  • Delivers treatment for vision problems the patient already has
  • Helps to develop a person’s visual abilities for when they’re in a classroom, workplace, playing sport or using a computer

Visual Stress Disorder Treatment in Melbourne

Visual stress disorder, also known as Meares-Irlen Syndrome, is a condition where a person, despite having normal vision, experiences reading difficulties, light sensitivity and headaches when exposed to agitating visual patterns.

It is estimated that around 5% of the population of Australia are affected by a visual stress disorder. These people have to work harder than others when trying to read, making reading a very tiring and unpleasant task for them. Many such people are unaware that using coloured overlays or coloured lenses could help them.

In many cases, the symptoms of stress and visual disturbances, as well as dyslexia, can be minimised by using coloured overlays placed over text or using coloured lenses placed in tinted glasses. Our Melbourne clinic is equipped with a colorimeter that can assess which colour tinted glasses will best suit each patient to reduce their symptoms.

Visual Stress Examples

  • Tiredness when reading
  • Headaches
  • Eyestrain
  • Movement of print
  • Blurring of print
  • Patterns on print
  • Letters change shape or size
  • Shimmering or shaking letters
  • Red, sore or watery eyes
  • Oversensitivity to glare

Signs of Visual Stress Disorder

  • Moving closer to or further away from page
  • Fidgeting
  • Restlessness
  • Skipping words and lines
  • Using the finger as a marker on the page
  • Constantly rubbing your eyes and blinking
  • Frequently re-reading the same line
  • Limited understanding of reading content
  • Frustration and low self-esteem

Test and Assessment

Our optometrist will perform a visual stress test by using an instrument called the intuitive colorimeter. The test will verify whether you have a visual stress disorder and will ascertain which of our coloured overlays or coloured lenses will help to relieve your symptoms.

During the assessment, the intuitive colorimeter autonomously changes the parameters of colour, hue, saturation and brightness while the eyes adapt to the colours. This will determine which precise colour is right for the coloured lenses we manufacture for a patient’s individual needs.

Eye Rehabilitation with Microprism Optics

Microprism Optics has developed a sound form of neuro-rehabilitative optometry that can be used to treat brain issues and restore vision in patients post surgery that a brain injury or concussion. Neuro-rehabilitative optometry can help integrate brain, vision and body function in patients with multiple sclerosis, Parkinson’s disease, and other neurological degenerative diseases.

In neuro-rehabilitative therapy, we rehabilitate the brain for better functioning and coordination of brain, vision and body.

Our Approach to Post Surgery Eye Rehabilitation

We think of vision in a holistic way, meaning that it has a flow-on effect to all other body operations. The brain is important because it interprets what our eyes see and creates our vision. Therefore, our vision is not just in our eyeballs − it’s a complex capability achieved through the interplay of multiple parts of the body.

Our behavioural optometrist is well versed in scientific theories that explain how the brain can change, heal and learn new ways of functioning through the development of new neural pathways. Combining this with cutting-edge developments in the use of prism glasses, we offer innovative methods of eye rehabilitation.

Book an Eye Rehabilitation Appointment Today

Due to our expansive knowledge of brain function and its interplay with the eyes and the rest of the body, we can treat vision issues by taking a very unique approack. Dr Michael Christian brings his background in neuroplasticity to the table in order to provide the best post surgery eye rehabilitation care possible to his patients. If you want nothing but the very best in eye care, call us today on (03) 9824 5431 to make an appointment.


What is Neuroplasticity?

Neuroplasticity is all about how the brain can change the structure of its network of neurons. Neurons are simply brain cells that send chemicals between each other to communicate a message throughout the brain and to the rest of the body.

If you say that the neurons have plasticity – the literal interpretation of the term neuroplasticity – this means that their patterns of behaviour can be changed, as they’re malleable. The brain can create new neurons, new connections between neurons, and can rearrange or get rid of older connections. So what does this mean for neuroplasticity therapy?

How Does Neuroplasticity Therapy Work?

In the past, scientists thought that the brain was static, but now we know that it can change, grow and even heal. Neuroplasticity therapy takes advantage of the brain’s ability to be retrained into different patterns of behaviour.

By helping the brain to create new networks of neurons, new behaviours can be established in the body. These lines of communication that support a desired therapeutic outcome – for example, strengthening the eye muscles – become fortified through practice and use.

The more a relationship of neurons is called upon in everyday life, the stronger it gets. That’s the basic principle behind neuroplasticity and neuroplasticity therapy.

Prism Glasses as Neuroplasticity Therapy

With the emergence of bevahourial optometry, the natural neuroplasticity of the brain can be leveraged for therapeutic purposes to improve vision. A recent scientific study has proven that the work of a behavioural optometrist – using prism glasses to correct eyesight problems – is a highly successful intervention.

Prism glasses use light itself to encourage eye muscle movement and redirection. The results experienced over time can be a vast improvement in vision capabilities and a reduction in prescription strength.

This effect of the prism glasses is only possible due to the process of brain neuroplasticity. By using the non-invasive neuroplasticity therapy, you may get impressive results as the brain relearns how to process visual information.

At Microprism Optics, we make the most of the latest advances in neuroplasticity and brain science to retrain your neurons to see more clearly. Our holistic approach treats the body as a complete ecosystem and acknowledges the brain’s role in creating new behaviour in the body.

What is Strabismus, Cross Eyes & Convergence Insufficiency?

Strabismus is a word that means while one eye looks at the object you want to view, the other eye looks elsewhere. The name of this condition originated from the Greek word strabismós, which means “to squint”.


When reading, a person with strabismus or turned eye convergence excess, may experience painful and inconvenient symptoms. These symptoms might include:

  • Eye strain
  • Blurring of vision
  • Double vision and
  • Headaches

Usually the brain will ignore the visual information coming from a misaligned eye, which can itself cause problems such as lazy eye or squint eye. But when a person with convergent strabismus tries to focus on something at short range, this causes a conflict in the visual information being processed by the brain, and the visual images become confused.

Not only does strabismus cause vision impairment, but it can also be psychologically damaging. It can impact a person’s self-esteem since it hinders the ability to make normal eye contact with others during conversation, which often leads to the affected person feeling embarrassed and awkward.

What Are the Causes of Strabismus?

Strabismus can be caused by neurological or anatomical issues that impede the control and function of an eye’s extraocular muscles, which regulate eye position and movement, causing both eyes to be misaligned in relation to each another. These issues may stem from the eye muscles themselves, or in the brain’s nerves or vision centres that manage binocular vision.

The Three Types of Strabismus

Types of strabismus or cross eyes compared to normal eyes

Types of Strabismus


When the misaligned eye looks inward, it’s called esotropia, or being cross eyed or having squint eye in colloquial terms. A specific example of esotropia that occurs intermittently is strabismus and convergence excess. In this case, the eyes may converge well enough to focus on an object in the distance, but may have trouble aligning to concentrate on a closer subject.


Exotropia is when one or both eyes are turned outward away from the nose; it is the opposite of being cross eyed. Various vision and physical health issues can be caused by eyes that do not focus and work together. When this occurs, the brain receives two different visual images; one is what the straight eye sees, and the other is what the eye facing outward sees. To prevent double vision, the brain will ignore the image that the turned eye is sending. This may cause the turned eye to deteriorate and eventually affect the ability to see.


Hypertropia is when the eyes are vertically misaligned, specifically when one eye is turned upward. It is the least common type of strabismus. When this happens, the brain receives two different visual cues; one from the straight eye and the other from the misaligned eye. The brain usually shuts off the signal it receives from the misaligned eye and focuses on what the unaffected eye is sending. This causes the misaligned eye to become weaker and eventually cause unbalanced vision.

Strabismus in Babies and Children

Strabismus in babies and children

It is believed that as many as 5 percent of all children are born with some type or level of strabismus. If either parent has strabismus, the likelihood that the child will also develop the eye condition is high. Children who have strabismus may experience double vision or eye strain. The condition in children will not go away by itself, meaning it will require treatment.

It is common for children who have this condition to be negatively perceived by other children. They can develop a high level of self-consciousness, anxiety and emotional distress, all of which can lead to emotional and mental health disorders.

Vision Therapy for Strabismus

Vivid Vision therapy for Strabismus

Drawing on scientific theories of brain neuroplasticity, Microprism Optics works with the innovative methods of Vivid Vision Virtual Reality to offer vision therapy for strabismus at our South Yarra clinic. It’s essential to begin vision therapy as soon as possible after diagnosis, especially in children. When convergent strabismus is left untreated, it can cause lazy eye in the misaligned eye due to that eye becoming weaker out of disuse.

There are a range of holistic behavioural optometry interventions that can be used to naturally and permanently treat strabismus and convergence insufficiency. Some of our patients may be prescribed prism glasses, while others may be advised to practice vision therapy exercises for strabismus.

What is Lazy Eye?

Lazy eye, or amblyopia, is a condition that usually begins in infancy. Baby lazy eye can easily occur when the child favours the use of one eye over another. This can happen due to a number of different underlying causes. The weaker eye may not look too much different than the stronger eye, which can sometimes make it hard to detect.

In the case of baby lazy eye, mothers might notice that when they cover one of their child’s eyes, the child cries or fusses. This usually means you’re covering the good eye and the child cries because they can’t see properly out of the weaker eye due to the amblyopia condition.


Diagnosis & Lazy Eye Treatment in Toddlers

It’s quite common for parents to seek lazy eye treatment in toddlers, as the amblyopia becomes apparent and parents are concerned about children being ready for starting kindergarten. If you suspect something is wrong with your child’s vision, seek out a lazy eye specialist.

Our behavioural optometrist in South Yarra, Dr Michael Christian PhD, can give a correct lazy eye diagnosis. As our approach is behavioural and holistic, our eye examinations take into account more possible causes than your typical optometrist. This is especially important when diagnosing lazy eye in children.

It’s always best to get a lazy eye diagnosis as soon as possible. This is true of lazy eye syndrome in adults or in children. If left unchecked, lazy eye can cause permanent disability and even legal blindness. The sooner you get a lazy eye diagnosis, the sooner you can embark upon lazy eye correction interventions.


Lazy Eye Treatment for Adults with Behavioural Optometry

If you’re concerned about lazy eye surgery cost, don’t be worried. Surgery is only necessary in some instances, and with the recent innovations in vision therapy for lazy eye in adults, there are many other options. If you see our lazy eye specialist Dr Michael Christian, he can conduct a thorough eye exam and advise on the best lazy eye correction methods to suit your particular eyes.

We take a holistic approach to vision therapy for lazy eye in adults, helping the muscles of the weaker eye to gain strength naturally. You may not even need surgery, as we offer alternative treatments such as lazy eye glasses and Vivid Vision Virtual Reality Therapy that can gently yet effectively correct vision.

Prescription Glasses from a Behavioural Optometrist

A behavioural optometrist works slightly differently than a regular optometrist looking at the relationship of behaviour to vision: to help your eyes recover from years of strain and improper use by retraining the eye muscles and sensory systems.

Making the most of the integration of body and vision such as prism insertions and Essilor progressive lenses, behavioural optometry can dispense prescription glasses with a difference. Using accepted and proven scientific principles of neuroplasticity, the extrapolation to ophthalmic prescribing, may actually improve your eyesight.


What Kind of Prescription Glasses Do I Need?

Essilor progressive prism lens glasses can lead to some very balanced and integrated visual care. But how do you know which kind of lenses you need?

Your optometrist will conduct a thorough eye examination. Not only do we look at individual eyes for eye chart eye chart purposes but their interaction binocularly with body posture, balance and movement . This is because you do more with your eyes than look at one gaze position. We’re interested in the holistic behavioural tendencies of your eyes. These eye patterns are so linked with the rest of the body that they can have an effect on concentration, balance and even emotional processing.

Once we have taken you through a comprehensive eye exam at our South Yarra clinic, we will have all the information we need to advise you on the kind of lenses that will help your eyes. We may recommend Essilor glasses or even glasses with a prism lens.


How We Can Help with Our Unique Prescription Glasses

You might find benefit from our prescription glasses if you:

  • Struggle with using bifocals but need glasses that cater for focusing at different space intervals – Essilor glasses are ideal for this.
  • Would like glasses with an anti-reflective coating for easier driving in the dark – Essilor glasses can come with a Crizal coating to eliminate all reflections.
  • Have been diagnosed with presbyopia (blurring in near vision) – Essilor glasses are a great choice.
  • Are a child or adult with learning difficulties relating to binocular vision issues – Glasses with a prism lens may help you.
  • Have suffered a brain injury or stroke and have vision issues as a result – A prism lens pair of glasses may help retrain your brain and aid your recovery.
  • Are struggling with your vision or current prescription glasses and would like a more holistic opinion – We’ll conduct an eye test to see what lenses would better suit your eyes.

Get Prescription Glasses with a Difference

As our practice is based on the discipline of behavioural optometry, we’re interested in the holistic behaviour of the eye.

The intention of Microprism lens formulations are to support and facilitate eye muscle movement whilst activating the optical, motor and sensory systems to change. Lenses focus the detail and clarity of any object at any given distance and directional prisms relocate the space and timing of what is being focussed on. Together the lenses and prisms aim to change eye muscle function, position, shape and subsequently vision. Distance, near, perspective and astigmatic issues are treated simultaneously to help bring eye position, vision, mind and body function into ease and correct alignment.

Each Microprism lens is uniquely derived and manufactured for each patient. Redirecting visual inabilities and fixed patterns using Microprism intends to improve vision and lower prescriptions.

Our prescription eyeglasses worn daily, are non-invasive eye training tools that aim to help the wearer do daily tasks with ease, exercising the eyes consciously and subconsciously.

The eyewear brands we stock at Microprism Optics are all high-quality optical and fashion brands that allow people to re-use their frames more than once.

We love robust yet light-weight frames, made from materials such as titanium and stainless steel that you’ll find in the Orgreen, Lightec, TITANflex and Safilo ranges. If you don’t like the appearance of glasses on your face, we stock minimal styles like the Silhouette rimless and Brendan O’Keefe (Australian-made) ranges. Keeping an eye on the trends in fashion, we have frames at our South Yarra clinic that suit all faces and styles. Brands such as Woow, Dutz, Ana Hickmann and Louis always design unique and fabulous styles.

Most of our spectacle frames come with a two year manufacturers’ warranty and complimentary frame adjustments and minor repairs for the life of the frame.

We also sell CooperVision and Bausch & Lomb contact lenses. Whilst prism cannot be incorporated into contact lenses, they can be a good option for sport or special occasions when you don’t want to wear your glasses.
