Children's vision 0.4 How much myopia

Children's vision 0.4 generally cannot calculate the degree of myopia.

0.4 is an expression of vision, which may be caused by hyperopia, myopia, amblyopia, etc. There is generally no direct conversion between myopia and vision. Children usually need to judge myopia degree by pupil dilation refraction, computer refraction, optometry, etc. under the operation of professional doctors.

If myopia is diagnosed, children can improve their vision by configuring glasses, orthokeratology, etc. according to their individual conditions. Bad eye habits should also be changed, such as rubbing eyes at will, using electronic products for a long time, lying down and watching TV.
