Among the nutrients recognised for their potential to support eye health, bilberry and lutein are particularly noteworthy. These compounds, often combined in supplement form, have been studied for their beneficial effects on vision and eye function.
What are bilberry and lutein?
Bilberry
Bilberry is a small, dark blue fruit related to the blueberry. Known for its high concentration of anthocyanins—potent antioxidants—bilberry has a long history in traditional medicine, where it has been used to support both vision and vascular health. These antioxidants help combat oxidative stress, which can damage delicate eye tissues, especially in the retina, where free radicals can accumulate.
Lutein
Lutein is a carotenoid, a natural pigment found in various fruits and vegetables, especially dark leafy greens like spinach and kale. In the human eye, lutein is concentrated in the macula, the central part of the retina responsible for detailed, central vision.
Lutein acts as a natural filter, shielding the eye from high-energy light, including harmful blue and ultraviolet (UV) rays, thus helping to maintain eye health and protect against long-term damage.
How bilberry and lutein support eye health
Caring for your eyes involves more than just regular check-ups; it’s also about nourishing them with the right nutrients. Bilberry and lutein for eyes have become well-known allies in supporting and preserving vision, especially as we face challenges from screen exposure and age-related eye conditions. Here’s how these two powerful ingredients work to protect and enhance eye health.
The benefits of bilberry for vision
Bilberries are particularly valued for their rich anthocyanin content. These antioxidants play a significant role in supporting eye health by neutralising free radicals, thus reducing oxidative stress, which is a primary factor in many eye conditions.
- Night vision support: Some historical accounts suggest that bilberries were consumed by Royal Air Force pilots during World War II to enhance their night vision. While more clinical studies are needed to validate this claim, bilberry’s role in promoting better adaptation to darkness has been explored in scientific research.
- Anti-fatigue properties: In today’s world, where many of us spend hours in front of screens, digital eye strain is becoming increasingly common. Bilberry’s antioxidant properties may help alleviate some of the symptoms associated with prolonged screen time, such as dry eyes and visual fatigue.
The importance of lutein in eye health
Lutein is an essential nutrient for eye health, primarily due to its protective role in the macula. Known as the eye vitamin, lutein accumulates the retina, particularly in the macular region. It acts as a natural blue light filter, protecting the retina from light-induced damage and oxidative stress.
- Protection against age-related macular degeneration (AMD): Age-related macular degeneration is one of the leading causes of vision loss among older adults. Lutein plays a crucial role in protecting the retina from oxidative damage, which is thought to contribute to the progression of AMD. The Age-Related Eye Disease Study 2 (AREDS2), conducted by the National Institutes of Health, found that supplementation with lutein reduced the risk of progression to advanced AMD by 25% in those at high risk.
- Cataract prevention: Studies also indicate that individuals with higher lutein intake have a lower risk of developing cataracts, a common eye condition that causes clouding of the eye lens. Lutein’s ability to reduce oxidative damage within the lens makes it an essential nutrient for long-term eye health.

How bilberry and lutein work together
While both bilberry and lutein offer individual benefits, combining them in one supplement may provide a more comprehensive approach to eye health.
The antioxidants in bilberry complement lutein’s light-filtering properties, creating a well-rounded defence system for your eyes. Many people turn to supplements that include both bilberry and lutein to protect their eyes against daily strains and age-related changes.
Supplementing with bilberry and lutein
Using lutein and bilberry supplements can be particularly beneficial for those who may not get enough of these nutrients through diet alone, especially if they’re at higher risk for age-related eye conditions. When selecting lutein and bilberry supplements, focusing on quality is crucial, as not all products offer the same effectiveness.
What to look for in a quality supplement
- Adequate dosage: Look for supplements that contain sufficient levels of bilberry extract and lutein. The specific dosage should be guided by healthcare advice or based on clinical recommendations for eye health.
- Reputable brands: Select supplements from trusted brands that adhere to good manufacturing practices and have positive reviews or endorsements.
- Combination products: If you’re looking to target eye health specifically, a supplement that combines bilberry with lutein may provide a more balanced formula.
