Causes and diagnosis of myopia
Myopia is a common vision problem, and many people are facing this problem. The main reason for myopia is that the long axis of the eye is too long or the curvature of the lens is too large. Factors leading to myopia include heredity, long term close eye use, high eye use, etc. When diagnosing myopia, doctors usually check their eyesight, and use ophthalmic instruments to detect the axial length of the eye, lens diopter and other indicators to determine the degree of myopia.
The degree of myopia is usually divided according to the diopter. Mild myopia is generally between - 0.5 and - 3.0 diopters, moderate myopia is between - 3.0 and - 6.0 diopters, and severe myopia is above - 6.0 diopters.
Correction of myopia with glasses
Glasses are one of the most common and convenient methods to correct myopia. Myopic glasses focus light on the retina of the eye through the use of concave lenses, thus improving the vision of myopic patients. It is very important to select the appropriate glasses degree. Only under the guidance of a doctor can the accurate degree be obtained to ensure the effect of vision correction.
For children and adolescents, glasses are the most common method of myopia correction. According to the doctor's advice, it is very important to check your eyesight regularly and update the appropriate glasses for keeping your eyesight healthy.

However, ReLEx SMILE surgery is not applicable to all myopic patients and requires detailed preoperative examination and evaluation.
