Retina holds the key to better vision in deaf people

Researchers from the University of Sheffield have found that the retinas in people who were born deaf, or were deafened in their early years, develop differently than that of hearing people. Specifically, deaf people tend to have better peripheral vision due to neuron placement. Previously, this enhanced vision was attributed to the part of the brain that processes visual cues, but now researchers believe the retina itself adapts to provide more visual input. These findings may offer clues in further improving deaf people’s vision.
