Some vision problems are unavoidable as they could be the result of injury, illness or genetics. However, when it comes to keeping our eyes as healthy as possible, there are simple steps we can take to help this. According to experts at Specsavers, diet can play a major role in preventing certain eye problems.
“Numerous studies have identified lutein and zeaxanthin to be essential components for eye health,” the study explained.
“Their role in human health, in particular the health of the eye, is well established from epidemiological, clinical and interventional studies.
“They constitute the main pigments found in the yellow spot of the human retina which protect the macula from damage by blue light, improve visual acuity and scavenge harmful reactive oxygen species.
“They have also been linked with reduced risk of age-related macular degeneration (AMD) and cataracts.”

As part of the research, leeks were listed among other vegetables that could promote healthy eyes alongside spinach, pepper, carrots and kale.
The study concluded: “Global researchers have identified lack of lutein and zeaxanthin as dietary causes in cataract and AMD related blindness.
“More research looking into the development of high-xanthophyll [which lutein and zeaxanthin are a type of] functional foods is essential in order to develop dietary strategies for the management of cataract and AMD in particular for elderly people.”
A separate study, published in Nutrients journal in 2018, also supported the consumption of lutein-rich foods.
It said: “Lutein qualifies as a powerful antioxidant and many studies support its favourable effects on eye health.
“Also, lutein has beneficial effects on other tissues, especially the brain, where it was associated with improved cognitive performance.
“Thus, not only high lutein intake with a diet rich in fruit and vegetables, but also its supplementation might be encouraged, particularly in the elderly and in individuals at high risk of different clinical conditions.”
AMD most commonly develops in people aged in their 50s and 60s. It initially affects the centre of a person’s visual field but can lead to vision loss in extreme cases.
