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. Behavioural Optometrists will explore these processes and use a range of treatments to help their patients learn and function more efficiently. This can be applicable to any age group – not just to children - and can also be of direct benefit to those following accidents and with possible traumatic brain injury.
