Millions of people aged 50 or over in the UK have undiagnosed sight or hearing problems, according to new research that has prompted calls for regular checkups. The study found that one in four in this age group – approximately 6.7 million people – cannot see clearly out of one or both eyes, while three in four – an estimated 20.3 million – suffer from some form of hearing loss in one or both ears.
The findings, based on examinations of more than 500 people in Peterborough and Cambridgeshire, reveal what researchers describe as 'widespread hidden sensory loss'. Many of those affected were unaware of their condition, with some reporting their hearing was better than tests indicated.
Professor Rupert Bourne, the study's principal investigator, said the figures were 'deeply concerning', adding that sensory health was being overlooked even among high-risk groups. He noted that despite free NHS eye tests for over-60s, much of the vision impairment could have been prevented.
Dr Jameel Muzaffar, a co-author and ear, nose and throat consultant, highlighted that many people have hearing problems they are not aware of. The research underscores links between untreated sensory loss and increased risk of falls, mental ill-health, social isolation, and dementia.
Sight loss alone is estimated to cost the UK £58 billion annually in lost productivity and healthcare burdens. The study authors recommend wider use of mobile diagnostic tests in non-hospital settings such as clinics and care homes to identify and treat sensory impairments earlier.
