INTERVENTION: Intervention 1: In the CAM procedure, five discs with different spatial frequencies (SF) (2, 6, 15, 20, 30 cycle/degree) will be presented to the patient (30 minutes, twice a week). Plates with SF equal to the two lines better than the measured baseline CDVA will be chosen. Total period of treatment is 3 months. Intervention 2: According to the guidelines of Amblyopia Treatment Studies (ATS), the standard occlusion therapy protocols, in the control group, will be as follows: In patients with severe amblyopia (CDVA worse than 20/100 or 0.8 logMAR) will be instructed to patch the non‐amblyopic eye 6 hours a day, and patients with moderate amblyopia (CDVA between 20/80‐20/40 or 0.3‐0.8 logMAR) and mild amblyopia (CDVA between 20/40‐20/25 or 0.2‐0.3 logMAR) will be instructed to patch the non‐amblyopic eye 2 hours a day without any extra visual training. Total period of treatment is 3 months. CONDITION: H53.02 Refractive amblyopia. ; Refractive amblyopia PRIMARY OUTCOME: The amount of uncorrected and best‐corrected distance visual acuity. Timepoint: 1, 2 and 3 months after amblyopia treatment. Method of measurement: Using E Snellen visual acuity chart. INCLUSION CRITERIA: Children between 4‐10‐year‐old Patients with unilateral functional amblyopia (due to anisometropia and/or strabismus) Patients who will be newly diagnosed with amblyopia and will be received their first management strategy Patients with CDVA worse than 0.8 (20/25)
