Is 150-degree astigmatism severe?

　　Astigmatism not only impairs visual acuity but also causes considerable inconvenience in daily life. If left untreated, the condition may progressively worsen—increasing treatment complexity and raising the risk of developing other ocular diseases, potentially even leading to blindness. So, is 150-degree astigmatism considered severe?

　　Is 150-Degree Astigmatism Severe?

　　A 150-degree astigmatism falls within the moderate range. Clinically, patients often experience pronounced symptoms, including blurred vision at both near and far distances. Typically, such patients require relatively greater accommodative effort. Individuals with 150-degree astigmatism commonly suffer from significant visual fatigue. In the past, adolescent patients with this degree of astigmatism could achieve improved visual acuity and enhanced visual quality by wearing properly fitted eyeglasses equipped with precisely aligned cylindrical lenses. Today, for adult patients with astigmatism, corneal refractive surgery is generally recommended.

　　Mild cases of 150-degree astigmatism may improve through lifestyle modifications—such as correcting poor eye posture and maintaining proper ocular hygiene. Many individuals develop astigmatism due to habitual misuse of the eyes. Therefore, promoting ocular recovery necessitates correcting improper eye habits. When reading or writing, ensure lighting is soft and adequately bright; maintain correct posture—avoid reading while lying down. Keep a distance of 30–40 cm between your eyes and the reading material. Similarly, pay attention to posture when watching television or using digital devices: screen height should be slightly below eye level, which helps prevent and manage astigmatism.

　　When reading, pay attention to appropriate lighting—avoid excessively bright or dim illumination. Insufficient lighting not only reduces visibility but also increases ocular strain, thereby elevating the risk of astigmatism progression. We hope this information proves helpful.
