If it is pseudomyopia, you can restore your vision to a certain extent through proper rest and correct eye exercises to avoid excessive use of your eyes.
If it is true myopia, proper rest and correct eye exercises can relieve eye fatigue and prevent myopia from deepening, but it can't restore vision. True myopia can be corrected by high-speed all-laser surgery, but not everyone can do laser surgery. Patients need to be over 18 years old, with no eye diseases and inflammation and sufficient corneal thickness. Before the operation, regular eye hospitals will give patients a very detailed examination to ensure the effect of the operation and the safety of patients.
If you don't want to have surgery, you can consider wearing orthokeratology glasses, which can not only correct your vision, but also control the deepening of myopia. And the orthokeratology mirror is very convenient. You only need to wear it when you rest at night, and you can see clearly without glasses when you work and study during the day.
The optometry in most optical shops is a simple computer optometry, which can detect the degree, but the optometry is not accurate and comprehensive, and it is not sure whether it is true myopia. At the same time, wearing glasses with inaccurate degrees will hurt the eyes and deepen myopia.
I suggest you go to the hospital for mydriatic optometry (using mydriatic optometry in the patient's static refraction state) to determine whether it is true myopia or pseudomyopia, and then determine the plan to restore vision.
