The incidence rate of myopia in children is increasing year by year in China, which is seriously endangering the health of children. The myopia rate among Chinese children was relatively low in the mid-1970s, accounting for approximately 15% to 20%. But there is a gradual upward trend from small towns, medium-sized cities to large cities, and there is a clear shift from the elderly group of children to the younger group.
The myopia rate of preschool children has increased significantly by two to three times compared to ten years ago. Among them, the myopia rate of kindergarten children aged six to seven has increased significantly from 7% ten years ago to 18%, with almost one in five children experiencing myopia. It can be seen that in recent years, the age of myopia in young children has shown a straight downward trend. In addition to the urgent issue of visual health care, it also shows the trend of the children's glasses market being highly valued and with unlimited business opportunities.
