Study shows superior vision among deaf people

12th November 2010

New scientific research has revealed that deaf adults may have advantages in terms of vision compared to those with normal hearing ability.

The University of Sheffield has conducted a study, sponsored by the Royal National Institute for Deaf People (RNID), showing that adults born deaf are able to react more quickly to objects in their peripheral vision than hearing people.

A computer game-style visual field test showed that this trait tends to be gained over time, as deaf children showed a slower reaction time to light stimuli at the edge of their visual field than hearing children of the same age.

Dr Charlotte Codina, leader of the study, said this was because deaf youngsters do not learn the ability to focus on items in their peripheral vision until their eyesight matures at age 11 or 12.

She added: "As research in this area continues, it will be interesting to identify factors which can help deaf children to make this visual improvement earlier."

According to RNID statistics, 840 children with significant deafness are born in the UK each year.ADNFCR-8000103-ID-800233140-ADNFCR
