Blurry Vision? Here Are the Possible Causes

Vision is our most dominant sense. It complements the other four senses and helps us interpret the world around us. So minutes before that decadent chocolate cake reaches our taste buds, our optic nerve has already sent a message to our brain that we’re about to taste an amazing treat. 

It’s no wonder, then, that when our eyesight is altered or damaged in some way, that our quality of life, as well as our sense of independence and well-being, can seem to take a hit. For many people, blurry vision is the first symptom that there’s something going on with their eyes. In this blog, the team of highly skilled doctors at Tayani Institute share their insights on the possible causes of blurry vision.

Refractive errors

One cause of blurry vision could be that refractive issues are preventing your eyes from properly focusing. Refractive issues include the following:


Nearsightedness is when you have problems seeing things that are far away. This condition occurs when your eyeball grows too long or the cornea is too steeply curved. 


Farsightedness is when you have trouble seeing things that are near you. This condition occurs if your eyeball is too short or the cornea is too flat.


Astigmatism occurs because the cornea is shaped oddly, thus causing distorted vision.

The good news is that prescription eyeglasses, contact lenses, or reading glasses can usually correct refractive errors and get your visual acuity back on track. 

Dry eyes

Another common cause of blurry vision is dry eyes. This condition occurs when there’s a tear-production issue or the quality of your tears isn’t sufficient enough to properly lubricate your eyes. Although you can suffer from dry eyes any time of the year, it’s particularly common during the winter months when the air is drier and lower in humidity. 

In fact, more than 16 million Americans suffer from dry eyes in the winter months. In most cases, the problem can be treated with a type of eye drops called artificial tears. Other treatment options, such as inflammation-reducing medications, may also help. Your doctor will create a personalized treatment plan to address the cause and severity of your dry eyes.

Digital eye strain

Another possible cause of blurry vision is digital eye strain. On average, Americans spend seven hours a day on a computer at the office or working from home. And then they spend yet more time texting, playing on tablets, or watching television.

Consider taking breaks every 20 minutes to rest your eyes. Wearing computer glasses may also help. Computer glasses can reduce glare and increase contrast. If you continue to experience blurry vision, make an appointment with your eye doctor to make sure there’s nothing more serious going on. 

Eye diseases

Blurry vision can also signal more serious conditions that, if left untreated, can cause blindness. You may be familiar with cataracts and glaucoma. An initial symptom of these two serious eye diseases is blurry vision. Unfortunately, both also share the dubious distinction of being leading causes of blindness. 

Other sight-threatening conditions that can cause blurry vision are diabetic retinopathy, diabetic macular edema, and age-related macular degeneration. In the case of macular degeneration, there’s no cure. However, there are ways to lessen vision loss and slow down the progression of the disease. Similarly, regular diabetic eye exams can help patients with diabetes better manage eye-related effects.
