People who are deaf benefit from better vision due to the fact their retinas develop differently, experts at the University of Sheffield have shown.

The research, which was funded by RNID -- Action on Hearing Loss and published June 1, 2011 in the journal PLoS ONE suggests that the retina of adults who are either born deaf or have an onset of deafness within the very first years of life actually develops differently to hearing adults in order for it to be able to capture more peripheral visual information.
