Optometrist says eat 19p item now to help avoid sight loss later
The specialist said our eyes are something many people overlook when it comes to looking after their health
We're told every day that diet impacts the heart, skin, and weight. But what's often forgotten is the eyes.
While young people may prioritise their skin, it could hinder them in the long run if they overlook their vision. However, an eye expert says there are things we can do to help us have strong vision well into our adult life - for as little as 19p.
Neil Laird, specialist optometrist at Pure Optical, said: 'If you care about your future eyesight, prevention really needs to start earlier - ideally, with your weekly shop. Age-related macular degeneration (AMD) gets talked about as an older person's disease, but by the time symptoms show up, a lot of the damage is already done."
He said large-scale studies suggest certain nutrients may help protect against the oxidative stress and inflammation that gradually damage the retina over time. But he said it's not all just down to eating leafy greens and salmon. In fact, some of the most effective nutrients for eye health come from places you might not expect.
What foods help make my vision better?
1. Lutein and zeaxanthin
The expert suggests picking up eggs, sweetcorn and some meats to help with this - and you can pick up individual eggs in most supermarkets now for around 19p. They explain that plant-based antioxidants such as lutein and zeaxanthin play a key role in filtering harmful blue light and protecting the central area of the retina.
2. Omega-3 fatty acids
These vital fats help maintain the structure of retinal cells and combat inflammation. Commonly found in oily fish such as salmon, sardines, and mackerel, they're particularly beneficial for young adults looking to establish lasting eye-health habits. For those who avoid fish, flaxseeds and walnuts provide a modest amount of omega-3s in the form of ALA.
3. Zinc and vitamin C
Zinc and vitamin C work together to strengthen immune defenses and reduce oxidative stress in eye tissues - a major factor in the progression of AMD. You can find these nutrients in foods like shellfish, citrus fruits, seeds, and red peppers. Oysters, in particular, offer a rich source and are ideal for those who want to try something on the fancier side.
Never do this
While a healthy diet supports eye health, certain habits can speed up the progression of macular degeneration. Smoking is a significant risk factor, as it restricts blood flow to the eyes and heightens oxidative damage.
Diets high in sugar, refined carbs, and trans fats are also associated with increased inflammation and added stress on the retina.
'We often blame screen time for eye strain, but what's really damaging vision in the long term is invisible - it's what's happening inside the retina,' Laird explained. 'Dietary inflammation and oxidative stress quietly build up for years. The good news is, this is one area where we really do have control, because what we eat can have a genuine, lasting impact on the health of our eyes.'
Vision-friendly diet - breakfast, lunch, snack and dinner ideas
• Breakfast: Boiled eggs with wholegrain toast and a citrus fruit• Lunch: Spinach and salmon salad with pumpkin seeds and olive oil• Snack: A handful of walnuts or sunflower seeds• Dinner: Grilled mackerel with steamed kale and roasted sweet potato'You don't need to cut everything out,' Laird added. 'You just need to work vision-friendly ingredients into your routine, most of which you're probably eating already.
"If you want to keep reading, driving, working, and simply seeing well into old age, start now. Your eyes will thank you later.'

Warning to instant coffee drinkers amid 'significant' link to eye disease
Chinese reserachers have said they discovered a statistically significant correlation between consumption of instant coffee and common degenerative disorder AMD Instant coffee drinkers have been handed a new warning by researchers who have discovered the beverage could be linked to a condition that robs people of their sight. Scientists from the Chinese Hubei University of Medicine have warned that people at high risk of age-related macular degeneration (AMD) should avoid slugging down the popular beverage, which accounts for roughly 13 percent of worldwide coffee consumption. An increasing number of people are living with the eye condition, which affects around 200 million people around the world at present, with 88 million more expected to be diagnosed with the disease in the next 15 years. While it mostly impacts the sharpness of people's eyesight when they reach their 50s, Hubei researchers have found that instant coffee is a potential exacerbating influence. Scientists found a significant statistical link between dry AMD disorder and the drink after studying the genetic data of more than 500,000 people. Corresponding author Siwei Liu, from the the university's Department of Ophthalmology at the Shiyan Taihe Hospital, said the results showed a "genetic correlation" not seen in decaffeinated or non-instant coffee. She said: "Our results revealed a genetic correlation between instant coffee consumption and dry AMD. Instant coffee may increase the risk of AMD, and reducing its intake could help prevent dry AMD." The scientist added that people deemed "at high risk for AMD" should "avoid instant coffee". Researchers believe that AMD is caused by a combination of factors, including diet, smoking habits and genes, with people likely to be more at risk of the disease if they have family members who suffer from it. People are also more at risk later in life, if they are white, obese, or if they suffer from cardiovascular disease, which affects the heart and blood vessels. Symptoms of AMD usually include noticeable loss of sight but not total blindness, with signs of the disease typically including: Visual disturbances like distorted lines and other features Shrinking central vision in one or both eyes Requiring brighter light when reading or working up close Difficulty adapting to dimming lights - such as in a cinemas or dimly lit restaurants Printed words seem increasingly blurry Impaired ability to recognise faces A blurry or blind spot within the field of vision that appears well-defined The Chinese researchers used data from diagnoses of AMD in the UK and additional statistics from the UK Biobank, which details how people consume coffee. Details included in the bank include whether the coffee was instant, ground or decaffeinated, and how much coffee people drank in total. While scientists found a correlation between AMD and instant coffee, they have stressed the results do not immediately indicate that coffee consumption can directly cause the disorder.
