Wouldn't it be a terrible mistake to take the health of your hard-working eyes for granted? Sun fatigue, eye strain, digital device light and lack of nutrients in the diet can lead to free-radical damage to your eyes—Swanson Synergistic Eye Health can help.Lutein and zeaxanthin are the only two carotenoids your body selects for protection in the eyes. One of the most important abilities of zeaxanthin and lutein is filtering out near-to-UV blue sunlight, potentially the most damaging wavelength of visible light, in the retina's light-sensitive macula cells. Sunlight is the largest source of blue light. Artificial sources of blue light include fluorescent light, LED TVs, computer monitors, smartphones and tablet screens. We are frequently exposed to blue light through the digital screens that have become ubiquitous in modern life. Lutein and zeaxanthin provide support for ocular health by absorbing blue light.
