Abstract

China has the highest incidence rate of myopia, and the number of teenagers with myopia accounts for more than half of the total number of myopia in the world. In recent years, With the increase of youth night home learning time, the impact of the night lighting environment in the home learning space on eye health has become increasingly obvious. This paper selects 112 home learning spaces of middle school students to carry out the actual measurement of lighting environment parameters and the satisfaction survey of the lighting environment, and through comparative experiments to explore the effects of illuminance, color temperature and lighting methods on eyestrain and visual efficacy. This Study found that under mixed lighting conditions, when the color temperature is 4500k, the illuminance in the range of 500lx-750lx is beneficial to relieve eyestrain and improve visual efficacy; When the illuminance is 500lx, a low color temperature (3500k) can help relieve eyestrain, and a high color temperature (6000k) can improve visual efficacy better. In addition, mixed lighting is better than local lighting for relieving eyestrain and improving visual efficacy. The results will help improve the night lighting environment in the home learning space of middle school students.

Highlights

2.2 billion people worldwide suffer from some form of visual impairment [1]
In 2018, the number of teenagers with myopia in China accounted for 53.6% of the total number of myopia in the world, while the proportion of teenager with myopia in other countries during the same period was much lower than that of China [4]
Due to the increase in the amount of homework for middle school students, the study time at home becomes longer, and the lighting environment of home night learning space is important for students' eye health

Summary

Introduction

2.2 billion people worldwide suffer from some form of visual impairment [1]. China is the country with the highest incidence rate of myopia [3], with 600 million patients with myopia. The increase in the incidence rate of myopia is a problem that deserves worldwide attention. This study found that eye health problems are related to age and habits with the eyes, and closely related to the amount of schoolwork and time with eyes. The lighting environment will bring the eye health threats, such as refractive error (myopia, hyperopia), retinal damage, etc., and harms the physiological functions of the central nervous system of the human body, and affects the circadian rhythm. The lighting environment will have a certain impact on people's learning ability, visual efficacy, and psychological emotions [6]
