Myopia
Conditions
Interventions
Low level red light group:The enrolled children were randomly divided into three low-intensity red light groups with different powers (650nm, 0.37mw ± 0.02mw
650nm, 0.6mW ± 0.2mw
650nm, 1.2MW), irradiating their eyes twice a day for 3 minutes each time, with an interval of = 4 hours
Maintenance treatment for 6 months.
Single focus glasses group:Only wear single focus glasses and observe for 6 months
