Lutein and zeaxanthin supplements are known for their benefits to eye health, particularly in reducing the risk of age-related macular degeneration (AMD). But what exactly are these supplements, and how can they help you maintain good vision?
What is lutein and zeaxanthin?
Lutein and zeaxanthin are naturally occurring carotenoids, pigments found in high concentrations in green leafy vegetables, as well as in some fruits and other foods.
These carotenoids are highly concentrated in the macula, the part of your eye responsible for central vision, and they play a critical role in protecting your eyes from harmful light and oxidative stress.
Unlike other parts of your body, your eyes cannot naturally produce lutein and zeaxanthin, so you must obtain them through diet or supplements.
In the UK, macular degeneration is a growing concern. According to Vision Matters, approximately 1 in 5 people over the age of 75 will experience some degree of AMD, and lutein and zeaxanthin supplements have become part of a proactive approach to maintaining eye health.
The benefits of lutein and zeaxanthin supplements
Protection against macular degeneration
Macular degeneration is one of the leading causes of vision loss in older adults. AMD, particularly, can severely impair your central vision, making it hard to read, recognise faces, or drive.
One of the most significant benefits of lutein and zeaxanthin supplements is their ability to protect your eyes from this condition. Research has shown that taking lutein and zeaxanthin may reduce the risk of macular degeneration and, for those already affected by it, help slow the progression.
Around 700,000 people in the UK are affected by AMD. Many UK residents now turn to the best lutein and zeaxanthin supplements for support, especially following findings from the AREDS2 (Age-Related Eye Disease Study 2), which highlighted the role of these nutrients in reducing the progression of AMD.
Protection from blue light
The modern world is dominated by digital devices – smartphones, tablets, computers, and TVs – all emitting high-energy blue light. This blue light exposure can contribute to eye strain and potentially harm the delicate tissues of the eyes over time. Lutein and zeaxanthin act as natural filters for this blue light, protecting your eyes from damage.
For those who spend long hours in front of screens or under artificial lighting, taking lutein and zeaxanthin supplements can offer additional protection, making them especially beneficial for today’s digital lifestyle.
Support for overall eye health
Lutein and zeaxanthin are powerful antioxidants. By neutralising free radicals, they help protect your eyes from oxidative stress, which can damage the tissues of the eyes and lead to various vision problems. This is particularly important for older adults, whose eyes become more susceptible to oxidative damage as they age.
The supplements also enhance visual function by improving the sharpness of vision and increasing contrast sensitivity, making it easier to see in low-light conditions or glare-heavy environments.
The importance of dosage and supplement quality
Choosing the right supplement means looking at the dosage. Most studies suggest taking at least 10 mg of lutein and 2 mg of zeaxanthin daily for maximum benefits.

Higher doses, such as 20 mg lutein and 4 mg zeaxanthin, are often used for those with higher risk factors for AMD or who experience significant eye strain.
Also, make sure to select a supplement with high bioavailability. This means the lutein and zeaxanthin are easily absorbed and used by your body. Supplements that are sourced from marigold flowers, for example, tend to offer higher bioavailability.
How lutein and zeaxanthin work in your body
Once you take lutein and zeaxanthin supplements, these carotenoids are transported to the retina, where they accumulate in the macula. Their role is to filter harmful blue light and neutralise free radicals, which are particularly damaging to the delicate cells of the eye.

Unlike other antioxidants, lutein and zeaxanthin specifically target the eyes, where they provide direct protection to the macula. This can prevent or slow the progression of AMD and improve overall eye function.
Who should consider taking lutein and zeaxanthin supplements?
While lutein and zeaxanthin are beneficial for anyone who wants to protect their eyes, certain groups can benefit even more:
- Older adults: People over the age of 50 are at a higher risk of developing macular degeneration. Lutein and zeaxanthin supplements can help slow this process.
- People who spend long hours on screens: If you spend a significant portion of your day in front of a screen, lutein and zeaxanthin can help protect your eyes from the harmful effects of blue light.
- Those with poor diets: If you don’t consume enough green leafy vegetables or other foods rich in these carotenoids, supplements can help you meet your daily requirements.
Protect your eyes and preserve your vision
Taking lutein and zeaxanthin supplements is a smart way to protect your eyes and preserve your vision, particularly as you age. Whether you’re worried about macular degeneration, eye strain from digital devices, or simply want to maintain good eye health, adding these supplements to your daily routine can make a big difference.
Incorporating Pure Optical’s Eyesight Plus, which contains lutein and zeaxanthin, is a smart choice for protecting your eyes and preserving vision as you age.
Be sure to choose high-quality products, follow the recommended dosages, and consult with your healthcare provider to ensure you’re making the best choice for your vision.
Frequently asked questions about lutein and zeaxanthin supplements
Can lutein and zeaxanthin help with digital eye strain?
Yes! These carotenoids filter blue light from screens, reducing eye fatigue, dryness, and discomfort. If you spend long hours in front of a computer or phone, supplementing with lutein and zeaxanthin may help ease strain.
Are lutein and zeaxanthin supplements beneficial for younger people?
Absolutely. While they are often associated with age-related eye conditions, younger individuals can also benefit—especially those exposed to excessive screen time or UV light. Starting early can help maintain long-term eye health.
How do lutein and zeaxanthin support brain function?
Research suggests these carotenoids contribute to cognitive health, improving memory and processing speed. Since they are present in the brain, their antioxidant properties help reduce oxidative stress, potentially benefiting mental clarity and focus.
Can lutein and zeaxanthin supplements improve night vision?
Lutein and zeaxanthin primarily support central vision and contrast sensitivity, which may indirectly help with night vision. While they don’t act as a direct cure for night blindness, they can enhance overall visual performance in low-light conditions.
Do lutein and zeaxanthin supplements have benefits for skin health?
Yes! These antioxidants help protect the skin from UV damage, reducing the effects of premature ageing and supporting skin elasticity. Some studies suggest they may also help improve hydration and overall skin tone.
