What is Blue Light?
People are aware of the damaging effects of sunlight. But most people don’t know about the high energy blue light emitted from electronic devices. We spend more than 10 hours every day in front of digital screens. High-energy blue light penetrates deep into the eye and is an emerging risk factor for eye health, fatigue and strains.
Blue light is part of the visible light spectrum. Throughout our lifetime our eyes are exposed to a variety of visible and invisible light, not just from natural sunlight where most blue light exposure comes from, but from the perpetual presence of electric lights in our homes, fluorescent and LED lights in offices, our flat screen television and computer screens, mobile phones and other digital devices as well.
How Blue Light Affect Our Eyes
Blue light is the closest to invisible, ultraviolet light on the colour spectrum. Almost all visible blue light passes through the cornea and lens and reaches the retina. Early research shows that too much exposure to blue light could lead to:
Digital eye strain
Blue light from computer screens and digital devices can decrease contrast leading to digital eyestrain. Fatigue, dry eyes, bad lighting, or how you sit in front of the computer can cause eyestrain. Symptoms of eyestrain include sore or irritated eyes and difficulty focusing.
Retina damage
Studies suggest that continued exposure to blue light over time could lead to damaged retinal cells. This can cause vision problems like age-related macular degeneration.
How Lutein and Zeaxanthin Protect against Blue Light
Lutein and zeaxanthin are two carotenoids in the same family of nutrients as beta-carotene, but they are specifically referred to as macular carotenoids because they are deposited in the retina when consumed. Lutein and zeaxanthin also have potent antioxidant benefits and play a role in protecting your retina from the cumulative damage and oxidative stress that leads to age-related eye concerns.
Supporting eye health isn’t just for older people anymore as high-energy blue light effects every agr group.
Lutein and zeaxanthin filter harmful high-energy blue wavelengths of light and help protect and maintain healthy cells in the eyes. The amount of lutein and zeaxanthin in the macular region of the retina is measured as macular pigment optical density (MPOD). Recently, MPOD has become a useful biomarker for predicting disease and visual function.
In short, the macular acts as a blue light filter and and gets depleted by blue light over time. Lutein and Zeaxanthin supplement (in 5:1 ratio) is essential to replenish the deplete macular.
Award-winning Lutemax 2020 provides all 3 of the macular carotenoids – Lutein, RR-zeaxantin and RS(meso)-zeaxantin. Lutemax 2020 has clinically demonstrated benefits including visual health and performance, sleep quality, eye strains and fatigue in people with long duration exposure to digital screens and other sources of high-energy blue light. Lutemax 2020 can help support eye health for a lifetime.
