10 Reasons Why Your Vision Is Blurry

Blurry vision and decreased perception of detail can have many causes. Some conditions that cause blurry eyesight are fairly harmless, while others are life-threatening.

Here are 10 possible causes of blurry vision.

1. Eye Strain

Eye strain is the least serious cause of blurry vision. Activities that may tire your eyes out include prolonged viewing of an electronic screen such as a laptop, smartphone, TV, or tablet. Other causes such as reading for a long time, and driving, especially in dim lighting.

The cure for eye strain is simply to take more breaks to allow your eyes to rest if you often look at a screen or regularly perform detailed tasks.

2. Conjunctivitis

Conjunctivitis (pink eye) is an inflammatory response to allergens, viruses, bad bacteria, or any other irritating substance. If you have redness in one or both eyes as well as blurry vision, you may be suffering from conjunctivitis.

3. Migraines

Migraines are painful headaches that sometimes follow the presence of an aura. Auras are visual distortions that include colors and blurry vision. Sometimes auras appear with minimal to no accompanying headache.

Migraines have many possible causes, so it can be difficult to determine whether they are serious or benign without a professional medical examination.

4. Diabetes

Blurred vision is a symptom that can accompany diabetes due to high blood sugar. In extreme cases, blurriness that results from diabetes can eventually turn into blindness. While some forms of diabetes are hereditary, the most common variation, type 2 diabetes, typically develops as a consequence of eating too much sugar and refined carbohydrates.

5. Glasses

If you wear glasses and have begun to experience blurry vision, your prescription could be outdated or an unsuitable match. Glasses that do not align with your visual needs can make your vision blurry and strain your eyes.

To see if your glasses are the issue, visit an eye specialist to examine you and see if you need a new prescription.
