There are usually several cases of blurred vision at night: 1, when looking at things at night because of the darker light, the pupil will be larger, if people with astigmatism, the symptoms of astigmatism will be highlighted when looking at things at night, and seeing things will be blurred due to the presence of astigmatism; 2, there are people who may not have a large degree of astigmatism, but the aberration of the eye is larger, the aberration is the imaging gap caused by the irregularity of the eye, at night When the pupil is also large, the aberration will increase accordingly, thus affecting the seeing. If you see something blurry at night, you should first go to the hospital for an optometry to check for astigmatism. If you have astigmatism, you can try to wear astigmatic glasses to see if you can correct your vision at night. If the improvement is not obvious by wearing glasses, it may be a factor of aberration, and there is usually no good way to correct aberration, but only slowly adapt to it, or pay attention to the safety of walking or driving at night.
