Myopia can be harmful to the health of the eye, for example, it may cause scleral staphyloma, macular degeneration, peripheral retinal degeneration areas, and even dry eye cracks with retinal detachment. Myopia is a common ophthalmic disease, a type of refractive error, usually occurs and develops along with the lengthening of the eye axis, the higher the myopia, the more the eye axis lengthening, which may eventually lead to limited scleral protrusion, forming scleral staphyloma. During the process of eye axis lengthening, the retina, being less resilient, may become damaged, resulting in the formation of macular degeneration. The retina in the periphery may also form areas of degeneration or even dry fissures, which may eventually develop into foramen ovale retinal detachment if left untreated. The likelihood of any of the above hazards or complications is low, and patients are advised to consult an ophthalmologist as soon as possible if they experience any discomfort.
