Pandemic of Childhood Myopia. Could New Indoor LED Lighting Be Part of the Solution?

Abstract

The existence of a growing myopia pandemic is an unquestionable fact for health authorities around the world. Different possible causes have been put forward over the years, such as a possible genetic origin, the current excess of children’s close-up work compared to previous stages in history, insufficient natural light, or a multifactorial cause. Scientists are looking for different possible solutions to alleviate it, such as a reduction of time or a greater distance for children’s work, the use of drugs, optometric correction methods, surgical procedures, and spending more time outdoors. There is a growing number of articles suggesting insufficient natural light as a possible cause of the increasing levels of childhood myopia around the globe. Technological progress in the world of lighting is making it possible to have more monochromatic LED emission peaks, and because of this, it is possible to create spectral distributions of visible light that increasingly resemble natural light in the visible range. The possibility of creating indoor luminaires that emit throughout the visible spectrum from purple to infrared can now be a reality that could offer a new avenue of research to fight this pandemic.

“…After the popularization of 3C electronic consumer products and the prevalence of mobile phones and tablets, excessive and improper behaviors and habits have led to a decrease in the age of myopia. The deterioration of myopia has accelerated, and the percentage of high myopia has also increased [1,2]. Han-Chih Cheng et al [3] investigated the risk factors for myopia and their influence on the progression of myopia in schoolchildren in Taiwan.…”
