What is behavioural optometry?

Behavioural Optometry is a specialism within optometry which can help to improve visual system issues caused by a range of conditions such as dyslexia or dyspraxia. At Harpenden Eye Centre, our fully accredited behavioural optometrist is one of only a small number of qualified experts in the UK and we are proud to host the only Behavioural Optometry and vision therapy clinics in Harpenden. 


"Behavioural Optometry is a specialist interest in how vision affects human performance. Vision and the motor visual system are our primary source for gathering information with 87% of learning occurring through the visual system. Even subtle issues with the visual system can have a major impact on our efficiency and performance, even more so for children where these systems are still developing.


Children are usually born with the necessary hardware to allow the development of normal sensory skills, but it takes a busy childhood of play, exploration and experience to develop and train the software that controls what we take in from the world. If this software is not established properly, it can result in problems with the visual system and therefore learning. If undetected these problems can continue into adulthood." The British Association of Behavioural Optometrists

What are the goals of behavioural optometry?

  • To prevent vision and eye problems from developing or deteriorating
  • To provide treatment for eye conditions which have already developed
  • To ensure the visual abilities needed in the classroom, workplace, playing sports or using computers are developed normally and work well
  • To help improve visual processing which can aid underlying conditions, such as dyslexia
  • To strengthen functional eye skills, just as you would want to strengthen weak hands or core muscles
  • To develop efficient visual skills which are just as important as developing motor, gross motor and coordination skills  

How can these goals be achieved?

Our behavioural optometrist will conduct an initial assessment with you or your child lasting around 2 hours. During this assessment, the optometrist will carry out a variety of tests and examinations and discuss your concerns. The optometrist will devise an action plan which will include weekly visual therapy sessions to monitor, assess and develop the visual skill set. 


These weekly visual therapy sessions will be required for a minimum of 3 months, though may be required for a period of 18 months or longer. It is imperative that you are committed to attending these weekly sessions and carrying out any exercises recommended by the optometrist at home for the goals to be achieved. Visual therapy is a process which requires determination and dedication. The success of visual therapy relies on the efforts of patient, as well as their parents or primary caregivers in the case of a child. It is important to understand that vision therapy is not a cure for the conditions which cause visual stress, but can help alleviate the symptoms if programmes and activities are followed exactly as instructed by our optometrist.
