Dry eye is a multifactorial ocular surface disease characterized by tear film dyshomeostasis, producing eye discomfort and visual impairment that seriously affects people's quality of life and quality of work. In recent years, the incidence of dry eye in children has been increasing year by year with the changes of environment and lifestyle, which has caused many concerns. Both genetic and non-genetic factors can affect the development of dry eye. However, non-genetic factors, such as lifestyle factors, can be improved by human intervention. Lifestyle modification is economical, safe and effective. It has proven to be efficient for preventing dry eye, so it is important to investigate the association between lifestyle and dry eye in children. Related studies analyzed the relationships between lifestyles such as video terminal, contact lens, low concentration of atropine eye drops, sleep, diet and dry eye in children. In this review, the above findings were summarized and relevant preventive measures were proposed, providing a new theoretical basis for preventing dry eye in children and delaying disease progression.
