However, a new study has shown that some deaf people, who were born deaf or became deafened early in life, actually do have better - or at least different - vision than other people. People who have this advantage have more of a focus on their vision towards the sides, while people with typical vision focus mostly on what is in front of them. Scientists discovered this by scanning the retinas of deaf people, and noticed a difference in the neurones on their retinas.
The study says that "a lifetime of sensory deprivation" can cause the physical parts of the body to reorganize themselves, to better cope. In addition to better side-vision, the study also mentions that deaf individuals communicating in American Sign Language show activation in the auditory cortex - not where you would expect activation to a visual stimulus.
I think this is all pretty cool. What do you think? Do you think you have better - or unique - vision compared to your hearing peers?
