Myopia of 500 degrees is mostly true myopia, which is currently irreversible, so patients cannot return to normal, but they may be able to correct their myopia with lenses or surgery to improve their vision. True myopia can lead to structural changes such as lengthening of the eye axis and myopic fundopathy, which generally cannot be reversed because myopia cannot be reversed. Myopia can lead to vision loss, which is generally more pronounced the higher the degree of myopia. Patients can improve their vision by wearing eyeglasses to correct their myopia. Adult myopia patients can also have surgery to correct myopia and improve their vision, such as corneal laser surgery and intraocular lens implantation. Myopia patients also need to develop good eye habits to avoid eye fatigue, which may lead to myopia progression and high myopia. Myopia patients are advised to seek timely medical consultation to assess their condition and follow the doctor’s instructions for treatment.
