Monocular amblyopia can be cured with active and reasonable treatment. In contrast, monocular amblyopia is more difficult to treat than binocular amblyopia because of the imbalance in vision between the two eyes, so the impact on the eye is greater. Once monocular amblyopia appears, treatment needs to begin immediately, and the earlier the age of treatment, the greater the chance of recovery. If amblyopia is detected in the eye before the age of 8, it has a better chance of being cured after active treatment. However, if you miss this age, for example, if amblyopia is detected after the age of 12, recovery will be more difficult. If the amblyopia is found in an adult, the chances of recovery are further reduced. Amblyopia in one eye can cause vision loss and may even lead to strabismus after a long period of time.
