What Causes Blurred Vision in Eyes?

Blurred Vision?

What causes blurred vision in eyes? Blurred vision isn’t something that should be ignored. Whilst tiredness or a common cold could be an occasional cause, regular episodes of blurred vision could be caused by something else, and could lead to more serious problems. We take a look at some of the most common causes of blurred vision and what can be done about them.

Refractive Eye Conditions

Refractive eye conditions are a common cause of blurred vision and include myopia (short sightedness), hyperopia (long sightedness) and astigmatism (where both distances cause a problem). This is easily identified by an eye test and corrected by prescription glasses or contact lenses.


You may not have heard the term very often but you will certainly be familiar with the condition. Presbyopia is an age related condition typically experienced in your mid 40’s onwards which impairs the eye’s ability to focus on close objects and like the conditions mentioned above, can be helped with glasses or contact lenses.

Dry Eyes

Dry eyes affects many people, and is caused by the eyes inability to produce sufficient moisture for the eye which is essential to protect it. This can be a result of occasional irritations such as the weather, allergies or blocked ducts. Many dry eye problems can be helped with the use of eye drops which can help to keep the eye moisturised and encourage tear production.

Ill Health

Blurred vision can happen as a result of common health problems such as cold and flu, migraines and hayfever. If blurred vision has come on at the same time as other symptoms associated with these conditions, the blurred vision should improve as the other symptoms are treated.


One of the most serious sources of blurred vision is a cataract, which unfortunately, like many other eye conditions, develop as we age. A cataract is essentially the clouding of the lens, which causes blurred vision and an inability to focus. Cataracts can be treated with surgery and many people are able to regain their sight following a successful procedure.

There are of course more serious causes of blurred vision and you should be extra cautious if you develop sudden blurred vision without an obvious cause or other symptoms.
