myopia

Myopia is a symptom in which the eye cannot see the distant object, but sees the near object clearly. Under the premise of refractive refraction, distant objects cannot converge on the retina, but form a focus in front of the retina, resulting in visual distortion and blurring of distant objects. Myopia is divided into two types: refractive and axial. Among them, refractive myopia is the most serious. Refractive myopia can reach more than 600 degrees, that is, high myopia.
