Why Does Your Vision Seem Worse At Night?

Does your vision seem rather clear during the day, but blurrier at night? Maybe you've just noticed a little annoying blurriness, or perhaps it's so bad that you're not comfortable driving at night. Here's a look at some of the most likely explanations for your symptoms.

Tired Eyes

Do you spend most of the day staring at a screen or completing intricate tasks that you really need to focus on? It's possible that your eyes are just getting tired by the end of the day. Blurriness caused by tired eyes is usually minor to moderate -- not severe enough to keep you from driving or partaking in other activities.

You can see whether tiredness is to blame by taking a day off from screens and other intricate activities. If your vision is not blurry that night, then you can blame the blurriness on tired eyes. To keep your eyes from getting so tired in the future, try:

  • Taking a break from your screen whenever you can

  • Only using your phone for necessary activities

  • Turning down the brightness on your screens

Lack of Vitamin A

A lack of vitamin A causes a condition called night blindness, which can result in anywhere from mild to serious visual blurriness at night. Do you eat a lot of red-orange fruits and veggies? If not, you may be deficient in vitamin A. Increase your intake by consuming more carrots, sweet potatoes, and other red-orange produce. You can also take a vitamin A supplement according to the instructions on the package. Your symptoms should ease up within a few weeks if vitamin A deficiency is, indeed, to blame for your blurry vision.


Cataracts occur when the lens of the eye starts to become cloudy, rather than clear. The cataract results in blurry vision, and the blurriness is often first noticed at night. Usually, if blurriness is caused by cataracts, you'll also see halos around lights at night. Your eye doctor can diagnose cataracts by looking at your eyes with a special microscope. If diagnosed, you may need to eventually undergo surgery to remove your cloudy lenses and replace them with artificial or donor lenses.

Don't just ignore visual blurriness that gets worse in the evening. Make an appointment with your eye doctor or Olympia Eye Clinic, Inc., P.S.. They can analyze your symptoms and give you a better idea of which of these conditions are to blame. It's never a good idea to leave any eye condition untreated, as it will just get worse.
