Sudden blurred vision can cause anyone quite a shock. One second you’re walking down the street and then you blink and suddenly you can’t quite make out the street signs in front of you.
Sudden blurred vision can sometimes affect both or just one eye. Either way, this can be a scary occurrence, especially if you are unsure what caused it. It will affect everyone differently and it can happen for a number of reasons.
It’s important to know the causes and treatments for sudden blurred vision. Experiencing it may seem like a cause for concern, but we can help you through the process with some all natural treatments.
What Causes Sudden Blurred Vision?
Truth be told, a lot can cause sudden blurred vision. It can be caused by pre-existing health conditions, gradual worsening of your eyesight over time, or a birth defect. Causes will vary from person to person. That’s why if you experience sudden blurred vision, you should speak to your eye doctor immediately to pinpoint the cause.
Here are some of the most common causes of sudden blurred vision:
- Floaters in the eye: Floaters are those little clear strands we sometimes see in the corner of our eye, but move away every time we try to look at them. As we get older, floaters become more common and denser, thus blurring your vision.
- Excessive wearing of contact lenses: Wearing your contact lenses for too long and too frequently can have some damaging effects on the eyes. We all know that wearing contact lenses overnight will dry out the eyes. Well, wearing your contacts for too long or too often will have the same effect. Dry eyes equals blurry vision.
- Chronic dry eyes: Which leads us to our next point – chronic dry eyes can cause blurred vision. When our eyes don’t get the lubrication they need, our corneas get blurred and produce a blurry image.
- Headaches and migraines: Ever had a headache after a long day at work and suddenly notice that your eyesight is blurry? Well your eyes aren’t just tired. Migraines and headaches can affect the area of the brain that controls vision. This can distort and blur the images being sent to the brain by the eyes.
- Astigmatism: Astigmatism is a refractive error in which the cornea is oddly shaped and reflects light into the eye unevenly. Unlike myopia or hyperopia, where things in the distance or things near the eye are always blurry, you never know what’s going to be blurry when you have astigmatism.
These are only a few of the main causes of sudden blurred vision. Several other conditions, such as myopia, hyperopia and presbyopia, can cause blurred vision. However, these refractive errors do not occur suddenly. They often develop over time as your eyesight gradually ages.
The symptoms of sudden blurred vision are easy to spot. Did you used to have good vision but now it has become inexplicably blurred? Then you probably have sudden blurred vision.
As mentioned, this can affect either one eye or both, depending on the cause. For example, when caused by a migraine or a headache, it may only affect one eye. It will usually affect the eye on the side of the head that is in pain. If your migraine seems to be really settling into the left side, chances are your left eye will be affected.
However, for cases caused by astigmatism, since both corneas are oddly shaped, the light will be distorted no matter what, even if each cornea is shaped differently from the other.
If the fuzzy and blurred vision isn’t enough to convince you that you have blurred vision, some other symptoms include poor night vision, eye pain (usually when accompanied by a headache or migraine), dry and itchy eyes.
Treatments for blurred vision can sometimes be a little tricky since the condition can be caused by so many different factors. If you experience sudden blurred vision that persists for longer than a few hours, you should talk to your eye doctor.
The first step in finding the right treatment for you is to find the exact cause. Your eye doctor may need to perform a slit lamp test and use eye drops to dilate your pupils to see what’s happening inside of the eye.
Here are the treatments available for the most common causes of sudden blurred vision:
- Astigmatism: The quick way to treat this cause is to have your eye doctor prescribe bifocals. The bifocals will fill in for your cornea in the spots that it is oddly shaped and help your eyes refract light better. However, the symptoms of astigmatism can also be alleviate by simply eating well. A balanced diet full of protein, beta carotene, omega-3 fatty acid and, of course, vitamin A can all help to treat astigmatism.
- Migraines and headaches: Blurred vision caused by headaches and migraines will often go away once the headache does, no treatment needed! However, if it persists, talk to your doctor immediately.
- Excessive contact wearing: This one has the simplest treatment. Lay off the contact lenses! Give your eyes a break. Try doing eye exercises that can help treat your refractive errors. You may find that you won’t even need your contacts again!
- Dry eyes: Omega-3s, omega-3s, omega-3s! That’s it! You want to be rid of dry eyes that cause blurred vision? Than make sure your eyes stay lubricated with upping your omega-3 fatty acid intake. This can be found in a lot of fish, fish oil, flax seeds and eggs!
- Floaters: The important thing to know about floaters is that they can be harmless if they’re small and appear sporadically. In this case, they can be treated by just relaxing and giving yourself a nice eye massage. Try limiting your exposure to screens such as your smartphone, tablet, computer or TV. Floaters that don’t go away easily and persist for long periods of time can be a sign of a more severe eye disorder. Talk to your doctor.
Sudden blurred vision can seem scary at first, but once you understand the cause, you can easily treat it at home. In fact, most of the time blurred vision is caused by stress. Just try to relax and take time to recenter yourself on those especially hectic days. Your health should come above all!
