Major Causes of Blurred Vision

Are you experiencing difficulties in seeing things clearly? Blurred vision is a common issue that many people deal with at one point or another. It may be benign and short-lived, or it could be indicative of something more chronic.

What do we refer to as Blurry Vision?

This refers to a lack of sharpness of vision, resulting in the ability to see fine details. However, it may result from abnormalities such as nearsightedness, farsightedness, presbyopia, or astigmatism. It can be improved with corrective lenses(eyeglasses) or it may signal the presence of eye disease.

If you notice any unusual or sudden change in your vision; it’s a sign that you should see an eye doctor as soon as possible.



Is an abnormality in the shape of the eye that prevents the eye from bending light properly?  People that are myopic can see things clearly up close but can’t see objects from far away. One of the major ways to notice this abnormality is when you experience difficulties in reading road signs. Myopia can affect one or both eyes and can be easily corrected with an eyeglass, contact lens, or refractive surgery.


This is the exact opposite of myopia. Hyperopia makes things like reading a book or working on a computer difficult without causing eye strain or fatigue. This abnormality can also be corrected with eyeglasses, contact lenses, or refractive surgery.


Is an age-related condition that typically affects people over the age of 40. It affects near vision, making close objects appear blurred. Treatment for presbyopia is not quite as straightforward as myopia or hyperopia, but there are a variety of options, such as bifocals or progressive lens (eyeglasses or contact) laser surgery, etc. Visit an ophthalmologist experienced in treating presbyopia.


Is a common vision problem caused by an error in the shape of the cornea. With astigmatism, the lens of the eye or the cornea, which is the front surface of the eye, has an irregular curve. This can change the way light passes, or refracts, to your retina. This causes blurry, fuzzy, or distorted vision.

5.Dry Eye

Is a condition in which a person doesn’t have enough quality tears to lubricate and nourish the eye. But the chronic dry eye can also cause distorted and blurred vision.


LASIK stands for laser in-situ keratomileusis, a popular surgery that can correct vision in people who are near-sightedness or far-sightedness, or who have astigmatism. Blurred vision can sometimes be a short-term side effect of LASIK and other types of refractive surgery. If you experience a blurred vision or any other issues after LASIK, contact your surgeon immediately for an evaluation.

7. Diabetic retinopathy

Is a condition marked by the abnormal accumulation of fluid causing retinal swelling, which in turn can impact the clarity of vision. Unchecked fluid build-up can progress to something far more serious than blurred vision. In the most serious cases, it can lead to retinal detachment and permanent blindness.

8. Eye Floaters

They appear as small spots that drift through your field of vision. They are often noticeable when staring at a computer monitor or a similarly bright, blank background. Chronic floaters or a sudden increase in the number of floaters in your vision could be a sign of something more serious like retinal detachment.

9. Pregnancy

There are multiple reasons as to why pregnant ladies experience a hazy vision. The most prominent reason is pregnancy hormones. They cause fluid retention which alters the cornea to make it thicker, along with an increase in the fluid pressure within the eyeball. This results in a blurred vision. If you are pregnant and experiencing any significant vision problems, consult with your doctor immediately.
