The long eye axis is mainly caused by physiological factors or pathologic factors, and generally can not be retracted, that is, the eye axis can not be shortened. 1. Physiological factors: the length of the eye axis will become longer with age, due to individual differences, some people’s eye axis may become too long, as long as it does not affect vision, it is generally a normal physiological phenomenon, without special treatment, but once the eye axis becomes longer, it will not be retracted. 2. Pathological factors: patients do not pay attention to eye hygiene, long-term overuse of eyes caused by high myopia, can cause the patient’s eye axis longer, this organic lesion is not reversible, patients can wear glasses to correct vision, but will not make the eye axis shrink back. Patients should pay attention to eye hygiene and avoid excessive use of the eyes, so as not to lengthen the eye axis, which will damage the patient’s vision. It is recommended that patients with abnormal eye axes should consult a doctor in a timely manner to assess their condition and undergo standardized treatment under the guidance of a doctor.
