Blue Light Exposure: Ocular Hazards and Prevention—A Narrative Review
Solar radiation of daylight consists of 24-30% blue light on average, according to the standards ASTM G173-03 and D65 [ 1 ]. The luminance of the sun at noon is 1.6 × 10 9 cd/m 2. The luminance of a clear blue sky is around 5000 cd/m 2 (compared with 300 for a TV display and 150-250 cd/m 2 for a computer screen).
The influence of blue light on sleep, performance and wellbeing in
Blue light might also have negative effects such as the decrease in sleep quality and sleep duration, which might worsen an athlete's physical and cognitive performance and recovery. Further research should explore if blue light can improve sleep, performance and wellbeing to significantly benefit athletic performance.
Research progress about the effect and prevention of blue light on eyes
INTRODUCTION. The refractive medium of the human eye's different tissue characteristics have different permeation effects on light when the wavelength is <300 nm. A wavelength between 300 and 400 nm can penetrate the cornea and be absorbed by the iris or the pupil. High energy short wave blue light between 415 and 455 nm is the most harmful.

Excessive exposure of the eye to blue light tends to cause a series of alterations, such as oxidative stress, mitochondrial apoptosis, inflammatory ...
Blue Light Protection, Part I-Effects of blue light on the skin
Lighting*. Necrosis. Sunlight. Low-energy and low exposure times to high-energy blue light can help prevent skin diseases, while studies have revealed that longer exposure to high-energy blue light can increase the amount of DNA damage, cell and tissue death, and injury, eye damage, skin barrier damage, and photoaging.
A review of the current state of research on artificial blue light
1. Introduction. Artificial light is pervasive in modern society, illuminating the places where we spend a large part of our time. We spend around 90% of our day indoors, and much of our exposure to artificial light is from the lamps we use to light these spaces [1, 2].Compared to natural outdoor light, artificial light is often much dimmer and has a different spectral distribution than sunlight.
