Botulism: 10 Symptoms of Botulism
Symptom #5: Blurred or Double Vision
Our eyes are located where they are because their position helps us to triangulate. Information about the light that is received by the eyes is then sent to the brain, which will then translate the information into something meaningful. If any part of this system is affected somehow, it can impact on our ability to see clearly.
Botulism attacks the central nervous system and paralyzes the muscles. This makes it difficult for the eyes to focus, resulting in vision that is blurred or doubled. If you do experience these symptoms suddenly, then you should arrange to speak with a doctor as soon as you are able to.
