Why Does Your Vision Get Blurrier At Night?
Do you find that you have trouble seeing clearly in the evening? Maybe your vision is relatively clear throughout the day, but once the evening hours set in, things start to look blurry. This symptom can be alarming, but the good news is, it usually has a rather simple, treatable explanation. Here's a look at the most likely causes.
Tired Eyes
These days, most people spend quite a bit of time staring at screens, from their phones to their work computers. This is not easy on your eyes. You have to really concentrate to see the detail on smaller screens, and the constant exposure to light can tire out the muscles that control your iris. By the end of the day, your eyes may simply be tired -- and your vision gets a bit blurry.
To keep your eyes feeling fresher for longer, take steps to minimize your screen time. Go down the hall and talk to a coworker in person rather than sending an email. Take a walk at lunchtime rather than spending it watching videos on your phone. Also, turn the brightness down on your screens, as this is easier on your eyes.
Dry Eyes
When your eyes are dry, your vision tends to get blurry. Eye dryness is also a result of hours of screen time. Environmental contaminants, like dust in the air or paint fumes, can also perpetuate eye dryness. Try keeping eye drops with you and using them every hour or two throughout the day. This way, you're fending off dryness before it gets to the point of making your vision blurry.
If eye drops alone don't solve your dryness issues, talk to your eye doctor. Dryness can be a symptom of various autoimmune diseases, and your eye doctor may recommend a prescription medication to increase your tear production.
Vitamin A Deficiencies
You probably remember your parents telling you that vitamin A, found in carrots, is good for your eyes. This is actually true, and a deficiency of vitamin A can lead to night blindness -- vision that gets worse at night. You could be in the beginning stages of night blindness. Try eating more fruits and veggies that are high in vitamin A. Carrots, oranges, sweet potatoes, squash, and spinach are all good choices. You may also want to take a multivitamin.
If you have ongoing issues with blurry vision in the evening, contact your eye doctor for diagnosis and treatment. To learn more, contact a company like Jo Johnson, M.D.
