True myopia of 75 degrees cannot be adjusted back. Myopia is categorized into true myopia and pseudomyopia. Pseudomyopia is reversible and can be restored to normal vision after active and effective intervention, but true myopia cannot. When myopia develops into true myopia, the eye has already developed organic lesions, so no matter what the degree of true myopia is, it cannot be restored, but the deepening of the degree can be slowed down through appropriate intervention. When true myopia occurs, if the change in vision affects your daily life, you should go to a regular eye hospital for optometry and wear appropriate glasses to correct your vision. You can also choose surgery to correct your vision after adulthood. After myopia, you should develop good eye habits to avoid eye fatigue, which will eventually lead to deepening of myopia.
