Book Appointment

They say eyes are the windows to your soul, but with a blurry and unclear vision, the world seems to fade away. So, before your world fades away, let us focus on the causes behind a blurry vision. Blurred vision is the loss of sharpness of eyes, which automatically makes every object look out of focus and hazy. Now let’s focus on the causes of blurry/unclear vision.

Refractive Error

This error is also recognized as a refraction error. It happens when light does not focus properly on the retina due to the structure of your eye. The most common types of refractive error are far-sightedness short-sightedness, presbyopia and astigmatism.

Blurred vision is the major symptom for refractive error and minor symptoms include eye-fatigue, sore head, and dual/cloudy vision.

Treatment for Refractive Error

We are here to rescue you if your vision is blurred because of refractive error. Firstly, wearing eye-glasses is a painless and manageable way to cure refractive error. Secondly, contact lenses can help as they become the initial layer where the light rays can refract while entering your eye, which causes accurate or error-free refraction.

In most instances, contact lenses offer a broader range of vision and exceptional comfort. They are a secure and fruitful option if used correctly. Frequently cleaning your lenses and washing your hands can lower the risk of eye infections.

However, there are certain conditions, where you are not allowed or cannot apply lenses. In this case, the third treatment option is refractive surgery. Although it might be a little expensive, it’s a guaranteed treatment as it modifies the structure of your cornea forever.

This modification in the shape of eye promotes a clear vision as the structure now allows the light rays to focus on the retina for a crystal clear vision.

Sudden Stroke and Preeclampsia

Apart from refractive error, there are certain medical conditions where you can feel a temporary blurry vision. For example, if you are experiencing a stroke, it would lead to a blurry image. Beside sudden attacks, pregnancy can also cause women to have a cloudy vision. This condition is known as preeclampsia.

Preeclampsia occurs when pregnant women suffer from the presence of protein in their urine and higher blood pressure. Such condition might not show any symptoms, but unclear vision and seeing flashy spots can be a sign that you might be suffering from one.


This is another cause of blurry vision. When we talk about headaches, it’s impossible not to mention migraine as a cause of blurry vision. Migraine has to be the worst type of headache, and it gets worse with time so does the vision. Drastic modification to your eyesight during a migraine is known as an aura. It can include the absence of bits of your vision, seeing flashing lights and minor spots, thus leading to emulsified vision. To prevent or treat migraine, a monthly check-up is crucial.

Bottom Line

It can be hard to cope with the world and still take care of yourself as there is so much going on, but your health should always be a priority. You can overcome blurry vision through constant check-ups and treatment.
