Astigmatism is a type of refractive error. If the astigmatism is mild, for example, up to 100 degrees, it does not cause vision loss and does not affect normal life, and driving is perfectly fine. However, if the degree of astigmatism is relatively large, for example, more than 200 degrees of astigmatism, it will cause a very obvious loss of vision, especially in the evening to see things very blurred, all the lights are scattered, will seriously affect the driving. Therefore, for astigmatism with a relatively large degree, it is recommended to wear glasses early, especially when driving a motor vehicle, to ensure clear visual quality, but also to ensure the safety of driving a motor vehicle. If there is astigmatism in the eyes, you need to go to the hospital as soon as possible to improve the visual acuity examination and optometry examination, to clarify whether you need to wear glasses.
