VisionLink Behavioural Optometrists provide research based treatment for convergence insufficiency, oculomotor dysfunction, spelling and reading problems, dyslexia, attention deficit disorders, Aspergers, Learning Related Vision Disabilities, Migraine and Acquired Brain Injuries and Sports Vision.

We are uniquely positioned to assist Visual Perception through the use of Vision Therapy, Irlen tinted lenses and Cellfield Intervention.

A Behavioural Optometrist is an Optometrist with extra training in binocular vision, Strabismus, Amblyopia and Visual/Spatial Perception. They are sometimes referred to as Neuro-Developmental Optometrists. Understanding Light, and the human-ness of that thing called Sight is a real challenge but Behavioural Optometrists have been doing this since 1930's and there is a lot of published research about it.

what is behavioural optometry

Behavioural Optometrists approach Vision from a different perspective to that of other optometrists and eye surgeons. You will learn a lot when you come to us.

We can help with "blurring words" despite “normal focus”, slow handwriting, loss of concentration, missing out words or letters when reading, reversing letters and numbers.

Helen Irlen was the creator of colored lens treatment protocol for perceptual processing difficulties. The Irlen Method has helped tens of thousands of patients by providing a long-term solution to reading problems, headaches, light sensitivity, ADD and ADHD, autism and many other ailments – by directly addressing a core problem: the situations in there has been an overwhelming of the brain’s inability to process Visual information. If you or your child have been suffering, then you deserve to know more about the most widely used, research-based, and most effective solution available to you.

The symptoms of Irlen Syndrome are wide-ranging, but the solutions -Irlen colored overlays and Irlen Spectral Filters (worn as either glasses or contacts) – are straightforward and available to you. Irlen addresses the underlying perceptual processing difficulties and light sensitivity that can contribute to reading difficulties, headaches, and attention difficulties.

Cellfield intervention

Cellfield is the first intervention to target the auditory, visual and motor pathways simultaneously. Cellfield targets visual, auditory and motor functions simultaneously. Clever software design expands working memory, strengthens attention and improves reading related motor functions.

Auditory – Specially designed sound parcels target auditory processing

Visual – Unique motion graphics and special lenses target visual processing

Auditory to Visual bridge – Cellfield is the only technology that bonds auditory and visual pathways, which allows the struggling reader’s brain to function more like a typical reader’s.

Motor pathways – To be truly effective, recent brain scan research shows that the auditory, visual and motor functions involved with reading must be activated and coordinated at the same time. This synchronized action allows the neural bonds between the letters and sound combinations to develop.  Linking auditory, visual and motor functions is vital to the reading process.


Our 8 year old grandson has had difficulty with his reading and because of this he has been falling behind in his class work.

A recommendation was made that the "Cellfield Intervention Vision Link System" may be of benefit to him. An appointment was made with Mark Eagle at "Shattky Optometrists" for an assessment which showed that he was 'dyslectic' and the program would suit.

Recently we were asked by our son and his wife to transport Eoin to some of the sessions under this system and we were able to sit in on these sessions. We would like to say how impressed we are in the progress he has made each week and also the confidence he has gained in himself and with his ability now to read aloud and enjoying doing so.

We understand that his school work has benefited greatly in that he has now progressed from a 'level 4' to a 'level 8' in his reading which means he is now near to the standard he should be for his age group. His spelling has improved as well and he is now only one stage lower than he should be for his age group.

We must also commend Renee with her ability to gain Eoin's confidence and friendship at an early stage which helped immensely throughout the course.

We would have no hesitation in recommending this course to any child with this type of disability.

Willow can now complete her homework, she is beginning to read for pleasure, her confidence is still much improved, sports skills also better, she is less tired after school which is an indication that her brain is less stressed/more efficient in the classroom environment, she often re-uses the Cellfield reading technique to speed herself back up again, her confidence is growing. She is a changed lass indeed!

We now have a motivated and confident student.

For us as parents it was important to understand that our beautiful daughter wasn't 'slow' to write and finish her work as her teachers constantly labelled her. She worked soo hard at her reading, and had finally gotten herself to a 'reading age' according to teachers, but, in my opinion she wasn't reading fluently like her brother and sister had at that age. Yes, she could read and understand each individual word, but reading was a laborious task for her, and each work was thought about, stunted and slowed. Writing was even slower.

We went away with this diagnosis and took some time to mull this over and consider whether or not to follow up with Mark's recommended treatment. Never were we pushed into following a treatment, and this was appreciated. We were naturally a little skeptical as there was a sizeable financial commitment as well as the huge time commitment; however, we wanted our daughter to have the opportunity to learn at the same rate as her peers.

At all stages of the program Mark was friendly, knowledgeable and professional, he explained every step and stage to me in a simple detail that made logical sense, he included our daughter in these conversations and empowered her by making her confident and proud of herself.
