Does 150-degree astigmatism require corrective glasses?

　　If astigmatism is present, optical correction can be used for treatment, primarily including eyeglasses and contact lenses. Corneal contact lens correction—also known as rigid gas-permeable (RGP) contact lens correction—may be recommended. For congenital high astigmatism or high astigmatism resulting from ocular surgery, surgical intervention is often required. So, does 150 degrees of astigmatism necessitate wearing corrective glasses?

　　Do I need glasses for 150 diopters of astigmatism?

　　Whether glasses are needed for 150-diopter astigmatism depends mainly on visual acuity and the degree of eye strain. In cases of regular astigmatism, visual acuity may remain unaffected. If no symptoms of visual fatigue are present, corrective intervention may not be necessary. However, if visual fatigue occurs—even with very mild astigmatism—appropriate corrective lenses should be prescribed following cycloplegic refraction. In principle, all degrees of astigmatism should be fully corrected; however, if high astigmatism causes discomfort or difficulty adapting, a lower correction may be prescribed initially to allow gradual adaptation before progressing to full correction.

　　Patients with astigmatism should avoid excessive eye strain. Daily habits should be adjusted accordingly—for instance, avoid reading or watching television while lying in bed. To prevent prolonged fixed gaze, frequent blinking is encouraged. Additionally, dietary modifications—such as increasing intake of eye-protective foods—can be beneficial. Patients should also adhere to regular ophthalmologic follow-up examinations.

　　Any concurrent ocular disease should be treated promptly. It is advisable to sit upright while reading, maintaining a distance of 30–40 cm between the eyes and the book. We hope this information proves helpful.
