Advantages: Matching a pair of suitable glasses is the best way to prevent myopia from deepening.

Disadvantages: Frame glasses make people feel "heavy", and the fog on the lens often makes people have a headache, so glasses need to be replaced every two years, which is very troublesome. Contact lenses also have some disadvantages. Because contact lenses are directly worn on the cornea, it is easy to cause diseases such as corneal inflammation. And contact lenses can't be put on and taken off at any time like frame glasses. Long-term wearing will cause many complications, such as corneal vascular hyperplasia, which will seriously lead to blindness.

2. Eye drops

We often see all kinds of advertisements for "dropping medicine to cure myopia", the main component of which is atropine. Expert's opinion: Atropine eye drops can flatten the lens and reduce the diopter by relaxing the ciliary muscle, which can just treat the changes of lens convexity and diopter increase caused by the continuous spasm and contraction of the ciliary muscle, and correct pseudomyopia to look up, but has no effect on the treatment of true myopia. Moreover, it is best not to use it when the quality of the liquid medicine is uncertain.

3. Surgical treatment of myopia

Advantages: Suitable for further studies, joining the army, athletes, civil servants, and friends who demand high appearance. Can be said to be the best operation. Laser surgery for myopia directly treats the corneal surface, and the mechanical strength of cornea has no obvious change after surgery. It is safe, computer-controlled, high in accuracy and stable in postoperative effect.

Disadvantages: Not everyone is suitable for myopia laser surgery, which has strict contraindications and preoperative examination.

4. Corneal shaping

Advantages: wear it at night, take off the mirror during the day, and the activity is not affected; Beautiful; It can correct myopia less than 600 degrees and astigmatism less than 150 degrees; 10 -35 people can wear it, with less age restrictions.

Disadvantages: the difficulty of lens cleaning and loading and unloading is the same as that of soft contact lenses; Keratitis often occurs due to improper collocation.
