Headaches, dizziness, nausea, fatigue and general overstimulation of the visual system by light, patterns, reading and perceived movement.
All the above symptoms are often a result of a disturbance of peripheral or spatial vision which normally provides a stable and coherent visual world in which we can move confidently.
Our visual system provides us with a spatial map that tells us WHERE things are in space. Vision guides our movement whether we are walking down the hall or reaching for a cup of coffee.
Since half of the cerebral cortex of the brain is devoted to constructing our visual world, it is not surprising that after a diffuse brain injury like a concussion, the visual system is affected.
1) Prism glasses worn all waking hours to ease your visual discomfort; this type of spectacle prescription can accelerate your improvements in other therapies you may be undergoing, such as occupational therapy, physiotherapy, and cognitive therapies.
2) Syntonic Light Therapy to make your visual system more comfortable and help
the healing process after the extreme stress to the brain/vision system as a result of the concussion.
3) Vision Therapy: Visual activities are introduced slowly so you do not start to feel your symptoms getting worse. We keep a close eye on you, in a weekly program, so we can adjust the program quickly, in a particualr activity is not working well for you.
One of the most important functions of our brain is to integrate the information from all our senses into a perceptual
whole, so we experience a stable, coherent, unified world.
If the visual spatial map is out of alignment compared to other body system maps, such as the movement system, then
this mismatch makes the brain's job to integrate all this information much more difficult, resulting in symptoms
listed at the top of this page.
People with concussions often feel best with their eyes closed, as this stops the mismatch between visual information and other information
coming to the brain.
With the prism glasses, the mismatch between the brain's visual spatial map and movement map is reduced.
No. You need a visual rehabilitation assessment.
These prism lenses affect your peripheral (spatial) vision. To determine a prism
prescription, various performance tests are carried out during the assessment, and the prisms that provide the most
enhancement of performance are the ones that are prescribed for you.
Most people find they have more energy, their headaches and dizziness symptoms
are better, they have better balance and they just feel better while wearing the prism glasses. The prisms
reduce the mismatch between systems so the brain can better integrate all the senses and movement into a perceptual whole, and promote faster healing.
Prism glasses look no different than regular spectacle glasses. They can have significant effects on balance as well as tracking eye movements while reading. See the video at the top of this page to see how vision affects balance.
This is application of visible light of particular frequencies (colours) through the eyes, permeating both the nervous tissue starting at
the retina as well as the blood and blood vessels of the retina.
This treatment has been used for over 70 years, and clincal observations continue to show improvements of symptoms in those who suffer from concussions. See http://Collegeofsyntonicoptometry.com
We go through with you a progression of activites that rehabilitate binocular vision ( eye teaming), visual attention, spatial reasoning, speed of information processing, visual memory, multisensory integration and visual motor skills.
