Abstract: Myopia, as the most common disease in ophthalmology, has developed into a serious international public health burden, the development situation is not optimistic. It is necessary to put forward new and effective intervention measures to curb the prevalence of myopia. In recent years, red light intervention to delay the progress of myopia has become a new research hotspot. Starting with the epidemic situation and inducement of myopia, this paper briefly introduces the commonly used clinical treatment methods, summarizes the research status of red light intervention in myopia, and discusses the possible mechanism of red light intervention in improving myopia. Some potential laser safety problems are put forward, hoping to provide reference for related research in the future.

Key words: myopia; red light; photobiological regulation; security; adolescence
