Ultra-high myopia can be protected by rational eye use, avoiding excessive eye rubbing and avoiding strenuous exercise. 1. Reasonable eye use: patients with hypermetropia need to pay attention to eye hygiene in daily life, avoid playing with cell phones, computers, TV and other electronic products for a long time, and develop the habit of reasonable eye use, which can control the continued growth of myopia, and it is more favorable to the protection of the eyes as well as the relief of eye fatigue. 2. Avoid rubbing the eyes with excessive force: Since the vitreous body of patients with ultra-high myopia has a certain degree of detachment and liquefaction, if the eyes are rubbed excessively for a long time, it may lead to deformation of the retina, cracks and detachment, so we should avoid external impact or rubbing the eyes with excessive force to protect the eyes. 3. Avoid strenuous exercise: As the eye axis of patients with hyperopic myopia is prolonged and the retina becomes thin, if they often exercise strenuously, the pressure on the fundus of the eye may increase, which may easily cause retinal detachment, so they need to avoid strenuous exercise. Patients with hyperopic myopia also need to have their fundus examined regularly so that problems can be detected early and early intervention can be made to minimize the occurrence of adverse consequences.
