Age-related Macular Degeneration (AMD) affects the macula, the part of the eye that allows a person to see fine detail and gradually destroys the sharp, central vision, which is needed for seeing objects clearly, and for common daily tasks such as reading and driving.

Although it rarely results in complete blindness, it robs the individual of all but the outermost, peripheral vision, leaving only dim images or black holes at the centre of vision and often stripping those with the condition of their confidence and independence.

With many of us valuing sight over any other sense, it is essential that we maintain our eye health, this can helped by ensuring you are receiving key nutrients such as Omega-3 fatty acids, Vitamins C, E and A and Carotenoids.

  • Omega-3 fatty acids: Our bodies are unable to produce Omega-3 fatty acids, so we must obtain them through our diet. DHA (Docosahexaenoic acid) is one such Omega-3. The highest concentration of DHA in our body is found within the retina, where it plays an essential role in regulating its function. Omega-3 fats are also thought to protect the arteries that supply blood to the retina. Omega-3 fatty acids can be found in: Oily fish, such as salmon, herring, mackerel, anchovies and sardines.
  • Vitamins C, E and A:  Are essential for eye health as they have antioxidant properties and therefore help protect against free radical molecules. Produced by the interaction of light and oxygen, free radical molecules can cause chemical damage to the retina. Studies have shown that people who eat adequate levels of antioxidants, which counteract free radical damage, tend to preserve their eyesight for longer than those who don’t. Vitamins C, E and A can be found in leafy greens = Kale / spinach / cress / parsley / leafy cabbage.
  • Carotenoids: Are natural fat-soluble pigments found in certain plants and provide the bright red, orange, or yellow colour of many vegetables.  Lutein and zeaxanthin are two carotenoids that accumulate in our retina, and are most concentrated in the macula and also occur in the lens of the eye. They act as antioxidants, protecting the tissue of the eyes by absorbing harmful blue light and neutralising harmful free radicals. As the body can’t produce lutein by itself, it has to be absorbed from food. Peppers, Carrots and Tomatoes are all a great source of carotenoids.

In an ideal world, our diet would provide us with all the vitamins and minerals we need - but evidence from the National Diet and Nutrition Survey shows that a significant proportion of the UK population simply doesn’t achieve nutritional sufficiency through diet alone. 

Ian Grierson, Professor of Ophthalmology at the University of Liverpool notes: “While research suggests that vitamins A, C, E and zinc can help keep the eye healthy, it is carotenoids, the pigments that occur naturally in plants and algae, which offer the most precise way of targeting the damage that causes sight loss. In particular, the carotenoids lutein and zeaxanthin act directly to absorb the damaging blue and near-ultraviolet light, in order to protect the macula. Any yellow or orange plants or vegetables contain them. They are also abundant in green vegetables such as kale and spinach.

“We should be eating 6mg of lutein a day, but the average consumption is only 2mg, which is way too low. In the Second World War, our average intake was 4-5mg and we weren’t even trying. But you cannot just eat vegetables alone, as lutein needs fat to be absorbed.  Egg yolk is one of the UKs main sources of lutein – there is not much there, but the little there is absorbed efficiently. That is why eggs Florentine is such an effective meal – the spinach is a high source of lutein and the egg yolk maximises absorption In fact, a 2005 study at the Ohio State University, Columbus, found that carotenoids absorption was enhanced by the consumption of avocado oil and fruit.”

So, what to do is you aren’t gaining all the nutrients you need from your diet?

“The advantage of nutritional carotenoid supplements is that the levels are much higher than those found in food, so supplementation is a much more reliable way of ensuring consistent levels of essential micronutrients are absorbed by the body. A supplement providing the right balance of lutein, zeaxanthin and Omega-3s is not only safe, but could protect eyes against future age related changes when diet alone fails to deliver,” note professor Grierson.
