The causes of astigmatism and blurred vision are closely related to genetic factors, excessive use of electronic products, and staying up late for a long time. You need to actively cooperate with your doctor to receive treatment. Astigmatism is mainly caused by the unevenness of the cornea, resulting in the formation of different refractive errors on different trajectories. When parallel rays of light pass through the uneven cornea, the refraction of the refractive system is unable to make the object form a clear focal point on the retina, but rather, it is not a clear image, so eyes with astigmatism will be blurred and difficult to see things. When astigmatism occurs, it is recommended to receive timely treatment. Common treatments include corrective eyeglass treatment and refractive surgery, and you need to choose the most appropriate option according to your specific situation.
