[0002] Long-term and continuous close-range eye use is an important cause of the development of myopia in children. To develop good and regular eye habits and ensure the quality of learning, parents need to use the latest eye protection technology to supervise their children's eyes. The light field display can project an imaging distance of 6m at a viewing distance of 30cm, and achieve a screen visual size of 200 inches, so that the viewer's eye adjustment is in a relaxed state, avoiding environmental factors that induce myopia. Children's eye use scenes, such as online teaching, cartoon animation, reading and writing paper homework, etc., can turn those close-range eye use times that are easy to increase the degree into "protection time" to relax the eyes and reduce children's visual fatigue.
