The Impact of Blue Light Exposure on Public Health and Protective Strategies

Abstract

This review offers an in-depth analysis of the implications of blue light exposure on public health, encompassing ocular diseases, such as ocular surface inflammation and retinal damage, alongside its potential impact on circadian rhythms, mood, and skin health. Amidst technological advancements and lifestyle changes, particularly during the COVID-19 pandemic, there has been a significant surge in indoor activities and the utilization of visual display terminals, thus highlighting the mounting concern over blue light exposure. The current study delineates the fundamental concepts, sources, and pathways of blue light exposure, and delves into the mechanisms underlying its health effects. Furthermore, it proposes a comprehensive array of protective strategies, encompassing adjustments in personal habits, dietary interventions, and medical safeguards. Future research endeavors should further elucidate the mechanisms of action of blue light to facilitate the development of more effective protective measures.
