It is much more likely that you will get into an accident if you cannot see the environment around you. This relationship gets stronger with more severe visual impairments.
If you have a visual impairment that cannot be corrected by lenses or compensated adequately by mirrors, you are at a higher risk of having accidents than someone who does not have a visual impairment.
One of the first set of records reviewed by insurance agencies when mulling over accident issues is the drivers health records. If an impairment is found it raises red flags.
Having worked in the Optometry field for over 13 years the answer to this question can be everything and nothing. The answer depends on the nature of the injury and the ability of the patient to adapt to the vision that the impairment has left them with. This would be better answered with more detailed information on the impairment.
Of course that those two are linked,because if you don't see very good you can't avvoide acidents like others can.. if you now that you have that problem,be careful
