Will it suddenly recover on its own?

Myopia is rare, but not impossible.

Usually, myopia is caused by a change in the shape of the eye, resulting in a loss of vision. However, in some cases, such as pseudomyopia or mild myopia, vision may be restored to some extent by improving eye habits, performing appropriate eye exercises, and reducing prolonged close eye use. Please note that this does not mean that myopia has been completely cured, as the shape of the eye may still differ from normal. Therefore, if myopia suddenly recovers on its own, it is recommended to seek medical attention in time for a detailed examination to determine whether it is a true vision recovery and to rule out the possibility of other potential eye diseases.
