Why does the child wear glasses, but the degree of myopia is still deepening?

Abstract: wearing glasses also helps to prevent strabismus. People with myopia have less adjustment when looking close, and the collection function of both eyes is weakened accordingly, which is easy to make their eyes deviate outward and produce strabismus.

if the eyesight of patients with myopia can reach a normal level through eye exercise, they can decide whether to wear glasses according to their personal needs for study and work, as well as their eye conditions and habits. However, it is generally recommended that they should wear glasses when they are tired.
