Interventions
Experimental Group:After wearing 0.05-day interval total aberration personalized correction lenses and going through a two-week elution period, 0.05-day interval single vision lenses were worn
Control group:Single-vision lenses with 0.05D intervals were worn. After a two-week elution period, total aberration personalized correction lenses with 0.05D intervals were worn
