Farsightedness and astigmatism are both in refractive error and need to be examined in a hospital for targeted treatment. Farsightedness refers only to external parallel light rays focused behind the retina and is usually associated with genetic factors, corneal diseases (congenital flat corneas, corneal trauma, etc.), lens diseases (age-related cataracts, posterior lens dislocation, etc.), and ocular tumors. Patients may experience vision loss, visual fatigue, and ocular changes, including smaller eyes and shallow anterior chamber. It can be corrected by optical prescription lenses or, depending on their condition, they can opt for surgical treatment. Astigmatism is a refractive irregularity of the eye that is related to the curvature of the cornea. Astigmatism is a refractive error of the eye and is mostly caused by congenital factors, such as heredity. In addition, astigmatism can be caused by disease, trauma, surgery, etc. Poor eye habits, lack of outdoor exercise and other triggers can promote the formation of astigmatism. Patients may experience blurred vision, visual fatigue and other symptoms. For patients with mild astigmatism, no special treatment is usually needed. In case of moderate or high astigmatism, it can cause amblyopia and requires refractive correction. In daily life, it is necessary to pay attention to eye hygiene and avoid staying indoors or using electronic products for a long time to avoid aggravating the symptoms of farsightedness or astigmatism in the eyes.
