July 30 - 15 | There are different ways to look at the visual system. For a rehab professional, it would probably be most useful to view vision as having two distinct systems...  the focal system
i.e. the eyeball (which focuses light and needs to be healthy to function properly) and the visual cortex (sight center of brain) and  the ambient system
responsible for spacial awareness - visual information going to non-sight centers of brain. It is possible to have eyeball injuries with MVA's and workplace accidents but those injuries are likely well documented and managed by eye care specialists. As a rehab specialist, you will likely by dealing with the much less well defined, less clear-cut symptoms and sequelea related to the ambient system. Dizziness, headaches and blurry vision can all come from injury to the ambient system.
The input (light energy) received through the eye is split when it hits the brain. Some of the visual information (nerve impulses) go to the visual cortex for processing as sight however much of the visual information is plugged into proprioceptive and balance systems. If the input traveling these non-sight centers of the brain does not match the historic/learned reference... confusion and consussive-type symptoms of headache and visual strain occur.
An occupational vision or vision therapy specialist can help with glasses and/or visual therapy to coordinate these systems and minimize symptoms.
