How to distinguish between high and low eye myopia standards?

Abstract: many children and adolescents have the possibility of pseudomyopia. Therefore, it can not be said that when they can’t see the distant target clearly, they must be myopia. Instead, they need to test their eyesight, including optometry.

usually takes 1.0 or 5.0 vision as normal vision, and those higher than these two standards are good vision. The degree of myopia does not mean that those lower than these two standards, but those lower than 4.8 are myopia. In the vision chart, the vision of 4.8 corresponds to 150 degrees, which can be converted to 150 degrees of myopia.

however, this number is not absolute. Many factors will affect it. When the degree is more than 300 degrees, it is really true myopia.

many children and adolescents have the possibility of pseudomyopia. Therefore, it can not be said that when they can’t see the distant target clearly, they must be myopia. Instead, they need to test their eyesight, including optometry. The adjustment ability of young children is relatively strong, so the possibility of pseudomyopia is also relatively large.

and

can restore vision when the monocular naked vision is less than or equal to 4.9. For many children and adolescents, they have strong adjustment ability, and their eyes are also in a developmental state. It is also possible for myopia to return to normal vision.
