SE: all myopic values were reported as absolute values; BCVA: best corrected visual acuity; LogMAR: logarithm of the minimum angle of resolution; mild myopia: SE >-3.00 D and ≤-0.50 D; moderate myopia: SE >-6.00 D and ≤-3.00 D; high myopia: SE ≤-6.00 D; PEP_Hori_Big: horizontal PEP (target 3°); PEP_Vect_Big: vertical PEP (target 3°); PEP_Hori_Small: horizontal PEP (target 1°); PEP_Vect_Small: vertical PEP (target 1°); SNR: signal-to-noise ratio; RDS0.8: stereopsis measured via random dot stereograms at 0.8 m from the screen
