Development in online learning and entertainment implies that young children are spending more time using electronic devices such as tablets and phones than ever before. Unfortunately, many of these electronic devices emit "blue light," which can potentially harm the eyes and disrupt sleep-wake cycles. While both children and adults have reasons to be concerned about exposure to blue light, children have a lower lens density than adults, and increased exposure to blue light can reach the retina, causing tension and oxidative damage.
Moreover, this issue is further complicated by the fact that many children do not receive sufficient essential nutrients for optimal visual and developmental health, putting them at greater risk.
Fortunately, research indicates that consuming docosahexaenoic acid omega-3 (DHA) and plant nutrients such as lutein and zeaxanthin can protect against blue light while providing essential nutritional support for the developing eyes and brain, promoting healthy cognitive and visual function.
Components:
Lutein and Zeaxanthin:
Lutein and zeaxanthin belong to a group of plant nutrients called carotenoids, which occur naturally and are synthesized by plants, algae, and bacteria. Beyond providing vibrant colors to various plants, carotenoids play a crucial role in antioxidation, including neutralizing free radicals and filtering harmful blue light that can lead to oxidative stress. They are further classified as xanthophyll, a subcategory of carotenoids containing oxygen. Lutein and zeaxanthin work together to form a protective layer in the retina called the macular pigment, offering crucial protection against short-wavelength light and other sources of oxidative stress. Importantly, the human body cannot synthesize lutein and zeaxanthin, necessitating their intake through food sources or supplements.
DHA (Docosahexaenoic Acid):
DHA is a long-chain polyunsaturated omega-3 fatty acid that plays structural and functional roles in cells throughout the body. Its significant presence in the brain's cortex and macular phospholipids underscores its vital role in brain and visual development. With over half the brain's weight composed of lipids, DHA constitutes the largest proportion of any fatty acid in the brain. In the eyes, DHA contributes to 50-70% of the fatty acids in photoreceptor cells in the retina, aiding in the containment of visual pigments and playing a crucial role in visual quality. Deeper evidence and the importance of DHA for visual and cognitive health are reflected in studies showing that lower DHA levels are associated with suboptimal visual and cognitive development in early-life, resulting in poorer cognitive and visual function throughout life.
