People with amblyopia can slowly stop blocking once their vision reaches normal levels, but the process must be gradual. Amblyopia is a condition in which the best-corrected visual acuity in one or both eyes is lower than that of the corresponding age, but there is no organic pathology in the eye examination. It is necessary to cover the affected eye during the treatment process, and when the vision slowly recovers, it is not possible to stop covering immediately after the vision has returned to the normal level, and slowly reduce the time of covering until it is no longer necessary to cover. If the masking is stopped too soon, it may cause the recurrence of amblyopia, so it is important not to remove the masking quickly after the vision is restored, but to follow the doctor’s instructions and gradually remove the masking.
