Orthokeratology lens is a kind of contact lens that is worn overnight at night. It is worn when sleeping every day and taken off after waking up in the morning, which can temporarily reduce myopia and obtain normal and good naked eye vision during the day. However, because it is worn in the eyes, there is a certain risk, and it still needs to be fitted in a regular and qualified medical institution. Clinical research shows that the infection is mainly related to the wearer's lack of training and education, incorrect wearing methods, improper nursing and untimely follow-up. In fact, parents now think it is not good to wear glasses and are unwilling to let their children wear glasses. In fact, reasonable glasses can improve vision, improve visual quality, promote binocular coordination, obtain good binocular vision and improve the quality of life. Whether to wear glasses depends on the child's actual eye needs and optometry results. Therefore, it is recommended that children find regular institutions to wear glasses.
