The various ways of shortening the eye axis that are currently available on the market are mostly unreliable, and there is currently no training method to shorten the eye axis. With the growth and development process from birth to adulthood, if the patient has high myopia, the length of the eye axis is in the process of continuous development without effective interventions. Currently, the more effective interventions are mainly surgical measures such as posterior scleral reinforcement, and there is currently no theoretical basis for trying to shorten the axial length of the eye through training. Patients can control the progression of myopia by increasing outdoor activities, reducing long-term close eye use and other adjustments in eye habits, thus controlling the continued lengthening of the eye axis. It is recommended that patients with abnormal eye axes should seek prompt medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
