Behavioural Optometry History - Now and into the Future


Behavioural optometry is a specialised area within optometry that considers the relationship between vision and behaviour. It focuses on how the visual system influences and is influenced by a person's behaviour, performance, and development. 

The history of behavioural optometry traces back to the mid-20th century when optometrists began to explore the broader aspects of vision beyond just eyesight. 

Key figures like Dr. William H. Bates contributed foundational ideas that influenced behavioural optometry in the late 19th and early 20th centuries. Bates proposed exercises and relaxation techniques to improve vision, emphasising the role of mental and physical relaxation in maintaining healthy eyesight. 

However, the formalisation of behavioural optometry as a distinct field began to take shape in the mid-20th century. Dr. A.M. Skeffington, an influential figure in optometry, played a significant role. He expanded the understanding of vision beyond eye health and acuity, considering how visual function affects daily activities and learning. Skeffington emphasised the connection between vision and the brain, stressing the importance of vision therapy and rehabilitation for various visual conditions. 

Dr. Skeffington's work laid the groundwork for the development of vision therapy—a key component of behavioural optometry. Vision therapy involves a customised program of exercises and activities designed to improve visual skills, such as eye-tracking, focusing abilities, and eye coordination. It's often used to address conditions like amblyopia (lazy eye), strabismus (eye turn), convergence insufficiency, and other binocular vision problems. 

Over time, behavioural optometry has evolved, incorporating advancements in technology, neuroscience, and understanding of human behaviour. It's gained recognition as a valuable approach in managing various vision-related issues, especially those affecting learning and performance in school or work environments. 

Today, behavioural optometrists assess not only visual acuity but also visual efficiency, visual processing, and how vision impacts an individual's overall functioning. They use a combination of lenses, prisms, vision therapy, and other techniques to address visual problems and enhance visual performance in everyday activities. The field continues to grow as research and clinical practice shed more light on the intricate relationship between vision and behaviour. 

Today, behavioural optometry involves a comprehensive approach to evaluating and addressing vision-related issues that go beyond traditional eye exams. Here's an overview of the process typically followed by behavioural optometrists: 

  • Comprehensive Evaluation:
    • Behavioural optometrists conduct a thorough assessment of not just visual acuity but also visual skills and how they relate to an individual's behaviour and performance.
    • This evaluation includes testing eye teaming, tracking, focusing, depth perception, and visual perception. It may involve using specialised tools and tests to assess these visual functions.
  • Case History and Symptoms Analysis:
    • Understanding the patient's history and any symptoms they experience is crucial. This includes discussing any vision-related difficulties, headaches, eye strain, or problems with reading, concentration, or coordination.
  • Binocular Vision Assessment:
    • Assessing how both eyes work together (binocular vision) is a significant part of the evaluation. This involves checking eye alignment, convergence (the ability of the eyes to move inward), and accommodation (focusing ability).
  • Visual Processing Evaluation:
    • Behavioural optometrists may also evaluate higher-level visual processing skills, such as visual memory, visual-motor integration, and visual perceptual abilities, to understand how the brain interprets and uses visual information.
  • Prescription and Lens Consideration:
    • In some cases, prescription lenses, prisms, or specialised glasses may be prescribed to address specific visual problems or to alleviate symptoms related to visual discomfort or strain.
  • Vision Therapy and Rehabilitation:
    • Based on the assessment, a personalised vision therapy program may be recommended. Vision therapy involves a series of exercises and activities designed to improve visual skills, enhance eye coordination, and address underlying visual issues.
  • Follow-Up and Monitoring:
    • Patients typically undergo periodic progress evaluations to monitor improvement and adjust the therapy as needed.
  • Collaboration and Referral:
    • Behavioural optometrists may collaborate with other healthcare professionals, educators, or therapists to provide holistic care for patients, especially if vision issues are impacting learning, behaviour, or overall development.

This process emphasises a holistic understanding of how vision impacts behaviour and performance, aiming to improve not only eyesight but also visual skills that are crucial for daily activities, learning, and overall well-being. 

Each patient's treatment plan is tailored to their specific visual needs and goals, promoting optimal visual function and comfort. 

Who can benefit from using behavioural therapy treatment? 

Behavioural optometry can benefit a wide range of individuals across different age groups and backgrounds. Here are some groups that may benefit from the services provided by behavioural optometrists:

  • Children and Students:
    • Children experiencing difficulties in reading, writing, attention, or learning may benefit. Behavioural optometry can address vision-related issues that affect academic performance, such as eye-tracking problems, convergence insufficiency, or focusing difficulties.
  • Individuals with Binocular Vision Problems:
    • People with eye coordination issues, strabismus (eye turn), amblyopia (lazy eye), or difficulties with depth perception can benefit from vision therapy aimed at improving binocular vision.
  • Those with Vision-Related Learning Disorders:
    • Individuals with vision-related learning disorders, where visual processing difficulties impact learning abilities, may find improvement through vision therapy and specialised interventions.
  • Athletes and Performers:
    • Athletes and performers often rely heavily on visual skills. Behavioural optometry can help enhance visual performance and improve hand-eye coordination, depth perception, and visual tracking, potentially boosting their overall performance.
  • Adults in the Workplace:
    • Professionals experiencing eye strain, visual fatigue, or difficulties with sustained near-vision tasks (such as computer work) may benefit from solutions provided by behavioural optometrists. This includes ergonomic recommendations and specialised lenses to reduce visual discomfort.
  • Individuals with Brain Injuries or Neurological Conditions:
    • Patients with traumatic brain injuries, stroke, or neurological conditions may experience visual problems that affect daily life. Behavioural optometry can offer rehabilitation strategies to improve visual function and quality of life.
  • Individuals with Developmental Delays:
    • People with developmental delays or conditions like autism spectrum disorder may have specific visual challenges. Behavioural optometry can address these challenges through tailored therapies and interventions.
  • Anyone Seeking Enhanced Visual Comfort and Performance:
    • Even individuals without diagnosed vision issues can benefit from behavioural optometry. Optimisation of visual skills and comfort can enhance overall visual performance in daily activities, reducing eye strain and fatigue.

Behavioural optometry aims to improve not just eyesight but the overall visual system, which plays a vital role in various aspects of daily life, learning, and performance. Tailored interventions and therapies can benefit individuals with a wide range of visual challenges, ultimately improving their quality of life. 

What is the future of behavioural optometry? 

The future of behavioural optometry holds several exciting possibilities and advancements, driven by ongoing research, technological innovation, and a growing understanding of the intricate relationship between vision and behaviour.
