Abstract:In China, the high incidence rate of myopia has become an important factor affecting children’s visual health. In the contemporary social environment, prolonged use of electronic products and reduced outdoor activities have become important causes of the development of myopia in children, which reflects the significant influence of light on myopia. This review was performed by searching PubMed data sets including research articles and reviews utilizing the terms “light”, “myopia”, and “hyperopia reserve”, and the review was concluded in October 2024. This article analyzes the impact of light on myopia, including light intensity, light wavelength, light frequency, light distribution, light rhythm, exposure time, and the impact of light exposure on hyperopia reserve, in order to provide new ideas for the prevention, control, and treatment of myopia, and to provide theoretical support for the development of more scientific and effective intervention measures.
