Do you notice that once the day starts to wind down and the sun sets, your vision becomes less clear? You may wonder if this change in vision is all in your head or if there's something seriously wrong with you. Chances are, neither of these worries are true. Blurry vision at night is quite common, and luckily, it is almost always caused by rather minor issues. Read on to discover the most common causes of blurry night vision and what you can do about them.
Vitamin A Deficiency
Blurry night vision, often called night blindness, is a side effect of vitamin A deficiency. You're most likely to be deficient in this vitamin if you suffer from celiac disease, cirrhosis, or another digestive system ailment that would reduce your ability to absorb vitamin A. Other symptoms of vitamin A deficiency include scaly skin and frequent respiratory infections. If you think you may be deficient in vitamin A, schedule a blood test with your doctor. Oral supplements or injections can correct the problem quite quickly, restoring your vision.
Too Much Screen Exposure
If you spend a good portion of the day sitting in front of a computer screen, this may explain why your vision is blurry at night. The brightness of the screen can strain your eyes, leaving them tired and less able to function at night, when seeing clearly is harder. Try turning down the brightness of your screen and taking breaks from looking at it every 30 minutes. If this does not work, talk to your eye doctor to ensure there is no underlying issue, such as nearsightedness, that is making your eyes work harder than normal during the daytime.
Cataracts
If you're an older adult, there is a good chance that your blurry night vision is being caused by cataracts. This is a condition in which the lens of the eye slowly becomes opaque. At first, vision seems blurry just at night, but as the disease progresses, it becomes blurry in the daytime, too. While cataracts are a bit harder to treat than the other problems mentioned in this article, cataract surgery has become quite common and routine. Visit an eye doctor if you think you may be developing cataracts; there are medications that can slow their progression so you don't need to have the surgery as soon.
If your vision is getting blurry at night, you should not ignore the issue. Chances are, the underlying cause is rather easy to treat, and if you treat it properly, you'll be back to seeing clearly in no time. Contact a facility like Wear Eyewear for an eye exam to discover the cause of your concerns.

Hello, I am Joseph Markets. I vividly remember my first pair of glasses, despite being only three when I started wearing them. The glasses had round lenses, flexible arms and straps that went around the back of my head. The glasses never broke despite me jumping, climbing and running around like crazy as I grew up. I always looked forward to receiving a new pair of glasses each year. I will use this site to talk about the various types of glasses available for children. I will also discuss ways parents can make wearing glasses fun. I hope you will use the information on my site to help your child embrace vision correction devices.
