In our modern world, our eyes are working harder than ever. Between smartphones, computer screens, and harsh LED lighting, we are constantly bombarded with high-energy blue light. So, what can we do to protect our vision as we age?

While a diet rich in leafy greens is a great start, sometimes we need a more concentrated boost. That is where Lutein steps in. Let’s dive into what this nutrient is and why the specific blend in Woods Health’s Lutein & Zeaxanthin may be a game-changer for your eye health.

What Does Lutein Do?

If you want the short answer: Lutein is a carotenoid (a plant pigment) that concentrates in the macula and lens of the eye. It helps to build macular pigment, acting as the eye’s natural filter for high-energy blue light.

Think of Lutein as internal sunglasses. Just as you wear shades to protect your eyes from the sun's UV rays, Lutein accumulates in the back of your eye (the macula) to absorb a large portion of excess blue light before it can damage the sensitive photoreceptor cells.

The Benefits of Lutein Include:

• Blue Light Filtering: provides support for digital eye strain.
• Antioxidant Protection: helps protect Lipid Membranes against oxidative damage.
• Visual Contrast: Can help improve visual sharpness and contrast sensitivity.

The "Power Trio": Why Lutein Needs Friends

While Lutein is the star of the show, it rarely works alone in nature. Other nutrients work in synergy with it, ingredients that work better together than they do apart.

The Woods Health formulation pairs 20mg of Lutein with two critical partners:

1. Zeaxanthin (2mg): Lutein and Zeaxanthin are almost always found together. While Lutein protects the outer edges of the macula, Zeaxanthin protects the very centre. They are the "dynamic duo" of eye health.
2. Astaxanthin (4mg): Often called the "King of Carotenoids," Astaxanthin is incredibly potent. Unlike some other antioxidants, it can cross the blood-retina barrier easily, helping to reduce eye fatigue and support blood flow to the fine capillaries in the eye.

Beyond the Basics: The Botanical Support System

What makes the Woods Health Lutein & Zeaxanthin supplement stand out is the inclusion of supporting botanicals and vitamins. You aren't just getting isolated Lutein; you are getting a comprehensive nutritional safety net for your eyes.

Here is a breakdown of the additional ingredients and why they are included:

Why Supplement? Can't I just eat carrots?

It is very important to eat a variety of healthy foods to support the body's various processes. To get these specific nutrients naturally, you should be eating plenty of:

• Kale and Spinach (Lutein)
• Orange peppers (Zeaxanthin)
• Salmon or Trout (Astaxanthin)

However, to get 20mg of Lutein daily, you would need to eat a huge bowl of raw spinach every single day. Supplements bridge the gap between a "good" diet and "therapeutic" levels of nutrition, ensuring your eyes have a constant reservoir of protection.

Frequently Asked Questions (FAQs)

Q: When is the best time to take Lutein?
A: Lutein, Zeaxanthin, and Astaxanthin are fat-soluble nutrients. This means they are better absorbed when taken with a meal that includes some healthy fats (like olive oil or avocado). You could take the tablet with your breakfast or lunch.

Q: How long does it take to see results?
A: Nutrition is a marathon, not a sprint. It takes time for Lutein to build up in the tissue of the eye (increasing your Macular Pigment Optical Density). Most studies suggest consistent use for a few months yields the best benefits for vision sharpness and protection.

Q: Is this suitable for older adults?
A: Absolutely. In fact, as we age, our natural levels of Lutein deplete. Supplementing becomes even more important for those over 50 to help maintain macular health.

Q: Why is Zinc often mentioned with eye health?
A: Zinc helps transport Vitamin A from the liver to the retina. While this specific formula focuses on the carotenoid profile, maintaining a healthy diet rich in nuts and seeds (which are high in Zinc) pairs perfectly with this supplement.

Macular pigment is a natural “filter” in the retina that contains lutein and zeaxanthin. It concentrates in the centre of vision, helping manage glare and high‑energy blue light. Studies have shown that diet and supplements may increase macular pigment levels over time.

If you’ve noticed headlights feeling harsher at night, screens seeming brighter than they used to, or that you squint more on sunny days, your macular pigment might be part of the story. Think of it as your eye’s built‑in blue light filter: a protective, yellow‑gold layer containing two plant pigments, lutein and zeaxanthin, that sit right where you need them most, at the centre of vision.

Meet your macular pigment: The eye’s natural blue light filter

• What it is: Macular pigment is a concentrated layer of carotenoids—including lutein and zeaxanthin—nestled in the macula, the part of the retina responsible for sharp, detailed vision. These pigments also occur in the lens.
• What it does: It absorbs high‑energy blue light and acts as an antioxidant, helping to manage glare, support contrast sensitivity, and keep visual tasks comfortable in bright or backlit environments.
• Where it comes from: Your body can’t make lutein and zeaxanthin. You get them from colourful foods and, if needed, supplements.

Why macular pigment matters more after 45

Our visual system changes gradually with age. Pupils don’t open as widely in low light, the lens can scatter more light, and recovery from glare can feel slower. Building and maintaining healthy macular pigment can help with:

• Glare comfort: Bright headlights, reflective roads, or a winter sun low on the horizon become easier to handle when macular pigment is robust.
• Contrast and clarity: Many people report sharper, more comfortable vision for everyday tasks - reading labels, recognising faces, or driving at dusk—when visual noise is reduced.
• Screen resilience: The pigment filters a portion of blue light, complementing sensible screen and lighting habits.

Lutein and zeaxanthin 101

• Lutein and zeaxanthin are antioxidant carotenoids found in foods such as dark leafy greens, peas, broccoli, sweetcorn, and egg yolks.
• Higher macular pigment levels are linked with better glare handling and contrast sensitivity. The effect builds gradually as the pigments accumulate.

Food-first ways to boost your macular pigment

Aim to include lutein and zeaxanthin on most days. Simple UK-friendly swaps work well:

• Leafy greens: Kale, spinach, spring greens, rocket.
• Green vegetables: Garden peas, broccoli, Brussels sprouts.
• Other sources: Sweetcorn, orange peppers, kiwi, and especially egg yolks, where the natural fats help absorption.
• Examples of how to cook for absorbability, as dietary fat helps your body absorb these pigments:
  • You could lightly sauté greens in olive oil,
  • add avocado or olive oil to salads,
  • or have poached egg on cooked spinach.

When supplements make sense

Even with good intentions, many of us fall short on greens. A simple lutein and zeaxanthin supplement can help you maintain a steady daily intake.

• Typical daily amounts: 10–20 mg lutein is commonly used in studies; many products also include zeaxanthin (often around 2 mg). Woods Health Lutein and Zeaxanthin is an easy add if your diet is light on leafy veg.
• How to take: With your main meal, ideally one that contains healthy fats (think olive oil, eggs, salmon, nuts).
• Timeline: It usually takes 8–12 weeks of consistent intake before improvements are noticeable; review how your eyes feel across a full season.

Everyday habits that complement your blue light filter

• Use daylight wisely: Read and work in good natural light when possible; avoid harsh overhead glare.
• Follow the 20‑20‑20 rule: Every 20 minutes, look 20 feet away for 20 seconds, and remember to blink.
• Regular eye tests: Book an eye examination every two years (or as advised) to keep tabs on overall eye health.

Safety and smart use

• Lutein and zeaxanthin are generally well‑tolerated. If you’re pregnant or breastfeeding, on long‑term medication, or under the care of an optometrist/ophthalmologist, check with your GP or pharmacist before starting a new supplement.
• Supplements support, but don’t replace, a colourful, healthy diet and routine eye checks.

Quick takeaways

• Macular pigment is your eye’s inbuilt blue light filter, which contains lutein and zeaxanthin.
• After 45, supporting this pigment may help with glare comfort and contrast for everyday visual tasks.
• Build it with leafy greens, eggs, and consistent supplementation if needed—taken with a meal and some healthy fat.
• Give it time: expect 8–12 weeks before judging the difference.

FAQ

What exactly is macular pigment?

It’s a concentrated layer of lutein and zeaxanthin in the retina’s centre that filters high‑energy blue light and supports visual comfort.

Can food alone provide enough lutein and zeaxanthin?

Yes, for some, especially if you eat foods that contain this on most days. If your intake is patchy, a daily lutein supplement can help maintain steady levels.

How much lutein should I look for?

Many people choose 10–20 mg lutein daily, often paired with a small amount of zeaxanthin, taken with food.

Will screen blue‑light settings replace the need for lutein and zeaxanthin?

Warm screen tints can feel more comfortable at night, but they don’t replace good lighting, regular breaks, and nutrition that supports macular pigment.

A gentle note on products

If your plate isn’t reliably leafy, a daily capsule such as Woods Health Lutein and Zeaxanthin can help maintain your intake of these key macular pigment nutrients. Pair it with sensible lighting and regular eye tests for a simple, eye‑kind routine.

Have you noticed your eyesight has worsened as you get older? Do you have problems reading or seeing the tv clearly? Do you have trouble seeing well enough to do everyday tasks? Or are you younger but constantly in front of a screen?

If you answered yes to any of these then you are not alone in your worries about your eye health.  A recent poll by Fight for Sight found that 38% of people in the UK who have been using screens more during lockdown, believe their eyesight has been negatively affected leading to difficulty reading, increased headaches & migraines and poorer night vision.

It is believed that 50% of the population over 75 years have age-related eye problems such as cataracts, macular degeneration, or glaucoma with 1 in 5 suffering from loss of sight.

However, the good news is that researchers and clinicians have found that the majority of these can be prevented, and the rate of deterioration slowed, through specific dietary and lifestyle changes.

Research indicates that someone is more likely to develop age-related eye problems when their body is repeatedly exposed to high levels of free radicals - the damaging chemicals created during periods of stress and exposure to smoke, ultraviolet light, and environmental toxins - and when their own supply of antioxidants – the dietary substances that help to neutralise free radicals – are low. This imbalance, along with genetic considerations is at the heart of most chronic disease and age-related eye problems.

So, what can you do to try and keep your eyes in the best health possible?

Visit an Eye Specialist

If you are noticing a change in your sight or having problems with your vision, you need to know what may be causing this and what the treatment options available to you are. The most likely conditions that you will be diagnosed with are: -

Age-Related Macular Degeneration (AMD) – is the slow breakdown and deterioration of the macula cells, a small yellowish area in the central part of the retina which is responsible for visual sharpness and central vision.

Cataract – is a clouding of the lens, the part of the eye that allows light to come in. It affects more than 50% of people over the age of 65 and is a common cause of a deteriorating vision.

Diabetic retinopathy - is a potentially blinding complication of diabetes that damages the eye's retina that affects up to half of all British people diagnosed with diabetes.  It occurs when diabetes damages the tiny blood vessels in the retina.

Glaucoma - is a group of diseases that can lead to damage of the eye's optic nerve, resulting in blindness. Typical symptoms include progressive loss of vision, headaches, difficulty focusing on close work.

Lifestyle – too much screentime.  Fight for Sight is encouraging those who have found their screen time has increased in the last year to adopt the 20-20-20 rule to help prevent eye strain. The rule recommends that for every 20 minutes spent using a screen, you should try to look away at something that is 20 feet away from you for a total of 20 seconds.

Eat a Healthy Diet

You need to eat a healthy diet that helps protect the eyes from free radicals. These antioxidants found naturally in foods called carotenes, particularly lutein and zeaxanthin are key for eye health.  Lutein is found in dark leafy vegetables such as broccoli, courgettes, spinach, kale and cabbage and Zeaxanthin in yellow and orange fruits and vegetables such as carrots, sweet potatoes, apricots, and peaches. Bilberries, blueberries, cranberries, cherries, and blackcurrants are all high in antioxidants and good for eye health.  Other foods to eat include oily fish such as mackerel, garlic, onions, tomatoes, brown basmati rice, almonds, walnuts, and pumpkin/sesame seeds.

Supplements

Many of us are unable to fully get the nutrients we need for optimum health from diet alone. Supplements therefore are not only of value in making up for what we are unable to get in the food we eat, some have been found by researchers to help prevent and slow the rate of deterioration of eye health by mopping up and neutralising excess free radicals. Look out for supplements that contain: -

Lutein – a powerful antioxidant which improves visual health by supporting healthy eye function and protecting against macular degeneration.

Bilberries - For decades bilberries have been associated with eye health and good vision.  The most effective use for bilberry extract appears to be strengthening and protecting veins and arteries, including those in the eye, thereby improving night vision and short-sightedness.

 Antioxidants such as vitamin A, beta-carotene, vitamin E and vitamin C can reduce the damage caused by free radicals thereby preventing or slowing the progression of eye disease. While these vitamins individually impact eye health, they become increasingly effective when used together.
