Dyslexia is a language based learning difference, however, many of the symptoms that are commonly associated with dyslexia can also be the result of vision problems. Vision therapy addresses problems that result from weaknesses in eye muscles or other problems in the way the eyes are used, through a series of exercises and skill-building sessions.
Therefore, it is very possible for a person to have both dyslexia and vision problems that can be addressed with vision therapy.
The visual skills, which can be developed and enhanced through visual therapy, include
Tracking - the ability to follow a moving object smoothly and accurately with both eyes, such as a ball in flight or moving vehicles in traffic.
Fixation - the ability to quickly and accurately locate and inspect with both eyes a series of stationary objects, one after another, such as moving from word to word while reading.
Focus Changing - the ability to look quickly from far to near and vice versa without momentary blur, such as looking from the board to a book or from the dashboard to moving cars on the street.
Depth Perception - the ability to judge relative distances of objects and to see and move accurately in three dimensional space, such as when hitting a ball or parking a car.
Peripheral Vision - the ability to monitor and interpret what is happening around you while you are attending to a specific central visual task.
Binocularity - the ability to use both eyes together, smoothly, equally, simultaneously and accurately.
Maintaining Attention - the ability to keep doing any particular skill or activity with ease and without interfering with the performance of other skills.
Visualisation - the ability to form mental images in your 'mind's eye', retain them for future recall, or for synthesis into new mental images beyond your current or past direct experiences.
These exercise can take place at a opticians, a visual therapy centre or at home.
