    Yes, the astigmatism will affect your night vision because people will have weaker vision at night than that at day. Since you have found that your vision is getting serious in night, you could go to have the eye exam to find the real prescription to have the eyeglasses to help you have the right vision. You'd better drive less at night.

    I am also having the symptom of astigmatism, the mean of this eye disease is refer to the inconsistent of refractive power of the eyes in different longitudes, or the diopter range different in the same longitudes. Under such circumstance, the parallel light get into the eyes, it can not form the focus points on the retina but form a line. It is one kind of myopia; it would be corrected by eyeglasses as myopia. If your prescription of astigmatism is below 50, it is no necessary to rectify by glasses; the affect will be so tiny to your vision in your daily life, no matter in daytime or at night. If the prescription is strong than 50, the doctor will suggest you to wearing a glass, thus there has no affect to your right vision the same.

    Yes, astigmatism surely makes your night vision worse. Astigmatism is a very common eye problem which affects many people all over the world. It is caused by distorted cornea, which causes different focal lengths. Because this slight different curvature of cornea or lens, the light passes through different focal length, so the vision is distorted. In day time, our pupil contracts, so pupil working as camera aperture provides more space for light to passing, which makes the blurry vision less noticeable. But in night, dilated pupil has less depth of space which makes vision problem more apparent. So while driving in night, I feel very bad, because of all these glare and halos of light. Usually I think it is better not to drive in night for people who have astigmatism. And you can do something to correct your vision. Have eyes examined by ophthalmologist and get a new pair of glasses or contact lenses, which can help solve your problem. As to glasses, you can require to add anti-reflective coating to your new glasses. This kind of coating could effectively prevent or reduce glare and halos of light. See your oculist at least once in a year, so that he/she could prescribe proper glasses according to your eyes, because the degree of astigmatism can change and improper glasses make your astigmatism just worse. Proper glasses are importance device for people with astigmatism, so remember to visit your oculist regularly on time.
