Blurry vision is one of the most common reasons patients visit us at Lake Norman Eye Care—and for good reason. Changes in vision can be unsettling, especially when they happen suddenly or interfere with your daily life. Fortunately, in many cases, blurry vision can be treated or managed effectively once the cause is identified.
What Causes Blurry Vision?
There are many potential reasons for blurry vision, and they range from simple refractive issues to more serious medical conditions:
1. Refractive Errors (Nearsightedness, Farsightedness, Astigmatism, Presbyopia)
The most common cause of blurry vision is a refractive error—meaning your eyes don’t focus light properly. Whether you’re nearsighted (myopia), farsighted (hyperopia), have astigmatism, or are experiencing age-related changes (presbyopia), the solution is often as simple as updated glasses or contact lenses.
2. Dry Eye Syndrome
Chronic dryness can cause fluctuating vision, a gritty feeling, or even watering. Blurry vision that improves with blinking may be related to dry eye, especially if you spend a lot of time on digital devices.
3. Eye Strain and Digital Fatigue
Spending hours on screens without taking breaks can lead to digital eye strain. Symptoms include blurry vision, headaches, and eye discomfort. Following the 20-20-20 rule—looking 20 feet away every 20 minutes for 20 seconds—can help relieve strain.
4. Cataracts
If you’re over 60 and your vision is becoming cloudy or colors appear dull, cataracts might be the cause. Cataracts develop slowly over time and are highly treatable with surgery when appropriate.
5. Serious Conditions: Glaucoma, Macular Degeneration, Retinal Issues
Sudden or progressive blurry vision, especially if it’s accompanied by flashes of light, floaters, or pain, can signal something more serious. Conditions like glaucoma, diabetic retinopathy, or retinal detachment require immediate attention to prevent vision loss.
