Blurry eyes at night
Reasons why your eyes may go blurry at night can include:
- You are tired so your visual system is fatigued.
- You have a refractive error such as long-sightedness or astigmatism. During the day, you may be able to compensate for these, but when your eyes are tired, your vision can go blurry.
- You could be mildly short-sighted. This may not bother you in normal light, but you notice it at lower light levels.
- The tears on the front of your eyes may be drying out if you have been around heaters and air conditioners all day. This may cause your eyes to go a little blurry, but should clear when you blink.
I only get it sometimes in the evening.
