According to eye experts, blurred vision can affect both eyes although it’s very much possible for only one eye to be affected. Commonly, the problem is due to refractive errors that can be corrected with the use of the right prescription glasses or contact lenses. Sadly, there are cases of blurring of vision that are due to eye problems that can cost you your vision.

Keep on reading to know some of the most common causes of blurred vision that you need to know about.

Refractive Errors

Astigmatism, nearsightedness (myopia), farsightedness (hyperopia) — all of these are refractive errors. Basically, they come into being when the curvature of the eyes is keeping light from focusing properly on the retina. Wearing prescription glasses or contact lenses can help in correcting refractive errors. Undergoing LASIK or laser eye surgery is also an option.


The unstoppable process of aging can cause unnecessary increase in the pressure inside the eyes, thus causing damage to the optic nerve. Eye experts say that it’s of utmost importance to deal with glaucoma as soon as possible in order for it to be kept from worsening, which is something that can easily lead to one’s loss of vision.

Another eye issue related to the aging process and can cause blurred vision called age-related macular degeneration. Simply put, it’s about the deterioration of the central portion of the retina called the macula. Age-related macular degeneration is considered as the leading cause of blindness in individuals who are 60 years old and above, say eye experts.

Older people are also at high risk of developing cataracts — the clouding of the lens situated in the front of the eyes. Cataracts can keep light from entering the eyes, thus causing blurred vision or even loss of sight if the clouding is severe. It’s a good thing that replacing the affected lenses with artificial ones can help in reinstating sharp vision.

Chronic Eye Dryness

Some people are suffering from what’s referred to as dry eye syndrome, and it’s something that can affect their vision in all kinds of ways, such as blurring. The administration of artificial tears is commonly recommended, although those who are suffering from severe dry eye syndrome may be recommended to take certain medications or use small devices called punctal plugs in order to keep their eyes lubricated.


Are you in the family way? Then don’t be surprised if it seems like your vision is blurry — hormonal changes taking place inside the body of a pregnant woman can change the shape or thickness of the cornea. Also, pregnancy can cause eye dryness which can affect your vision just like what’s discussed earlier.

Diabetic Retinopathy

Just like what the name says, diabetic retinopathy is seen in individuals who are battling diabetes. Having high blood sugar can cause damage to the blood vessels, including those that supply the retina with much-needed oxygen and nutrients. Poor blood circulation to the eyes can wreak havoc on the retina, leading to what’s called diabetic retinopathy that can cause blindness if diabetes is not put under control effectively.

Cardiovascular Issues

Someone who is suffering from high blood pressure or hypertension may end up with blurred vision or even loss of vision as a result of damage to the blood vessels in the eyes. An individual who is having a stroke may also experience blurring of vision. Needless to say, seeking immediate medical attention is warranted in order to keep serious complications at bay.
