True myopia of 175 degrees can be corrected by wearing glasses and refractive surgery. 1. Wearing glasses: Through refraction examination, such as computerized optometry, comprehensive optometry, etc., we can get the accurate refraction and choose to wear frames or corneal contact lenses of corresponding prescription to correct the vision. 2. Refractive Surgery: Adult patients may consider refractive surgery for correction, but they need to do some examinations to assess the condition of their eyes before surgery.
