The widespread use of light-emitting diodes (LEDs) has increased blue light (BL) exposure, raising concerns about its potential adverse effects on ocular health. Prolonged exposure to BL has been implicated in the pathogenesis of various retinal disorders, including age-related macular degeneration (AMD), primarily through mechanisms involving oxidative stress and inflammation mediated by the overproduction of reactive oxygen species (ROS). This review synthesizes current evidence on the photoprotective properties of dietary bioactive compounds, (e.g., anthocyanins, curcumin, quercetin, myricetin, and resveratrol), with a focus on their potential to mitigate BL-induced retinal damage. Accumulating research suggests that dietary antioxidants, particularly polyphenols, may offer photoprotective benefits. These phytochemicals act by neutralizing ROS and enhancing the retina’s endogenous antioxidant capacity. Based on these findings, this review advocates for a food-first approach in future investigations, emphasizing the development of evidence-based dietary recommendations to bolster retinal health and mitigate the risk of BL-related ocular diseases. Considering the current lack of empirical clinical studies examining the impact of BL on human ocular health, future research in the field of BL hazard should prioritize two key approaches: conducting large-scale epidemiological dietary surveys and implementing clinical trials on functional ingredients that have demonstrated beneficial effects against photodamage in preclinical animal studies.

The increasing prevalence of blue light (BL) exposure from modern light-emitting diodes (LEDs) has raised significant concerns regarding its potential adverse effects on ocular health. Prolonged exposure to BL has been implicated in the pathogenesis of various retinal disorders, including age-related macular degeneration (AMD), primarily through mechanisms involving oxidative stress and inflammation mediated by the overproduction of reactive oxygen species (ROS). This review synthesizes current evidence on the photoprotective properties of plant extracts and di-etary bioactive compounds, with a focus on their potential to mitigate BL-induced retinal damage. Accumulating research suggests that dietary antioxidants, particularly carotenoids and poly-phenols, may offer photoprotective benefits. These phytochemicals act by neutralizing ROS and enhancing the retina's endogenous antioxidant capacity. Based on these findings, this review advocates for a food-first approach in future investigations, emphasizing the development of evidence-based dietary recommendations to bolster retinal health and mitigate the risk of BL-related ocular diseases.
