The difference between eyes with astigmatism and eyes without astigmatism lies in the impact on vision, difficulty of prescription and surgical correction. 1. Impact on vision: Patients with astigmatism may experience blurred vision, double vision and other discomforts, and patients with astigmatism are more prone to headaches, visual fatigue and blurred vision when using their eyes for a long period of time. 2. Difficulty of prescription: Patients with astigmatism are usually more difficult to prescribe glasses than those without astigmatism. When prescribing glasses, not only do you have to consider the effect of nearsightedness or farsightedness on your vision, but you also have to take into account the effect of astigmatism on your vision. 3. Surgical correction: Patients without astigmatism can easily undergo surgical correction, whereas patients with astigmatism have various restrictions, such as some corrective surgeries require patients to have astigmatism of less than 600 degrees. It is recommended that patients with astigmatism consult a doctor to evaluate their condition and follow the doctor’s instructions for treatment.
