Research indicates that a significant portion of the Oxford population may be failing to obtain essential nutrients required for maintaining optimal eye function.
A newly published study found that 81 per cent of residents in the area expressed concerns that their daily diets might be deficient in the specific nutritional elements necessary for preserving healthy vision.
Just 19 per cent of those surveyed expressed confidence that their existing eating habits supplied everything required for good ocular health.
The findings emerge as National Eye Health Week gets underway from September 21 to 27, prompting fresh examination of public awareness around eye care nutrition.
Dr Nisa Aslam, a general practitioner with expertise in nutritional medicine, highlighted that three-quarters of Oxford residents surveyed accepted declining vision as an inevitable consequence of ageing rather than something that could potentially be mitigated through dietary choices.
She emphasised that adopting appropriate nutritional habits could contribute meaningfully to supporting long-term eye health and decreasing susceptibility to various ocular complaints, which appear to be impacting a substantial proportion of the population.
The research also uncovered that an overwhelming 94 per cent of participants expressed anxiety about how progressive vision loss might diminish their overall quality of life.
Observable changes were already evident among those questioned, with 44 per cent reporting that their sight had deteriorated as they had grown older, 86 per cent describing worsening visual acuity, 43 per cent citing physical discomfort, and 29 per cent experiencing either blurred vision or tired eyes.
Despite these widespread concerns, understanding of which foods actually promote eye health remained notably limited, with only 44 per cent of Oxford residents able to identify beneficial options.
Clinical nutritionist Suzie Sawyer observed that many individuals continued to hold outdated assumptions while remaining uninformed about specific nutrients that scientific research has connected to maintaining normal eye function.
She pointed out that over half of those surveyed, 56 per cent, mistakenly believed carrots represented the most effective dietary approach to protecting their vision, and when asked which food they would prioritise for improving their ocular health, 69 per cent immediately named carrots.
Sawyer explained that while carrots do provide certain beneficial compounds, they are not the only or necessarily the most important source of relevant nutrients.
She noted that carrots contain two of the three macular carotenoids essential for eye function, specifically lutein and zeaxanthin, which concentrate in the macula, the central region of the retina responsible for detailed central vision.
Numerous other food sources also provide these critical nutrients, including dark leafy greens, various orange and yellow produce, and oily fish species such as trout, salmon and sardines.
Despite this, only 19 per cent of Oxford residents demonstrated any awareness of macular carotenoids, and a mere 13 per cent recognised either zeaxanthin or lutein by name.
The study’s authors suggested that nutritional supplements could potentially bridge these dietary deficiencies, particularly for individuals who find it challenging to consume the recommended daily intake of five portions of fruit and vegetables.
With Oxford residents collectively rating their eye health at only 6.1 out of 10, both Dr Aslam and Ms Sawyer urged members of the public to give greater priority to eye-friendly nutrition and to explore supplementation where appropriate.
