Blurry vision causes: Have you ever opened your eyes and noticed things look fuzzy or out of focus? Blurry vision can be scary, especially if it comes on suddenly. It may be nothing, but it could also indicate a problem with your eyes or health.
Here are 8 common causes of blurry vision:
You need glasses: One of the most common reasons for blurry vision is simply needing glasses. In case you already have them, it’s time for an update. If you have trouble seeing far away or up close, you might feel things are blurry. Scheduling an eye test and getting a properly fitted pair of glasses or contact lenses can clear things up fast.
Dry eyes: Your eyes need moisture to stay comfortable and see clearly. If your eyes don’t produce enough tears or if the tears evaporate too quickly, your vision can become blurry. It’s common if you work long hours on the screen or live in a dry or windy place. You can use lubricating eye drops or take screen breaks and blink more often.

Eye infections or allergies: A pink eye infection or seasonal allergies can make your eyes red, swollen, or bloody. You might notice that your eyes have watery or sticky discharge, or they may feel itchy or painful. If it’s an allergy, over-the-counter drops might help you. For infections, especially if you see yellow or green discharge, it is best to see a doctor.
Eye strain: Have you been staring at your phone or computer for hours? Eye strain is becoming common due to prolonged screen time. Your eyes, like any other part of your body, wear out when they work too hard or for too long. You might get blurry vision or headaches. Switch to dim lighting and keep your screen at eye level. Furthermore, spend some time away from the screen.
Migraine: At times, blurry vision may appear before or during a migraine, a phenomenon known as a visual aura. You might notice flashes of light, zigzag patterns, or temporary blind spots. Resting in a dark, quiet room can help ease the discomfort. If migraines are frequent, consult your doctor to discuss possible treatment options.
High blood sugar: In people with diabetes, high blood sugar can affect the eye’s lens, leading to episodes of blurry vision that may come and go. Vision often improves once blood sugar levels are brought under control. However, over time, consistently high blood sugar can damage the small blood vessels in the eyes, increasing the risk of long-term vision problems.
High blood pressure: Blurry vision can also be caused by high blood pressure. When your blood pressure is too high, it can damage the blood vessels in your eyes, leading to vision changes. In extreme cases, it can cause sudden vision loss or a medical emergency.
Serious eye conditions: Sometimes blurry vision is a warning sign of more severe eye problems, like cataracts, glaucoma, or retinal detachment. Visit a doctor immediately.
