There are several reasons why your vision may be blurry at night. One reason is the change in lighting conditions during the day and night. The eyes need more light to see clearly, and when the amount of light is less, it can be harder to see objects clearly.

Another cause of blurred vision at night may be a condition called myopia. This means that your eyes have a hard time focusing on objects that are far away, and can cause blurry vision at night when objects are farther away and dimly lit.

Other possible causes of blurred vision at night are astigmatism, cataracts, glaucoma or a condition called 'night blindness', which is a reduced ability to see in low light. If you have persistent blurred vision at night, it is important to speak with an eye doctor to determine the underlying cause and refer you for appropriate treatment.
