Blurred Vision: What Are The Causes?

Blurred vision can be a frustrating and concerning vision problem that affects many individuals. It may occur in one or both eyes and can interfere with daily activities.

Let’s explore the various causes of blurred vision, as well as how to address and relieve this condition.

What is blurred vision?

Blurred vision refers to a loss of sharpness and clarity in one's sight. It can manifest as fuzzy or hazy eyesight, difficulty focusing, or a general reduction in visual acuity.

Blurred vision can affect people of all ages and may be temporary or chronic, depending on its underlying causes.

What are the common causes of blurred vision?

Refractive Errors

Refractive errors, such as nearsightedness, farsightedness, and astigmatism, are the most common causes of blurred vision.

Wearing corrective lenses, such as glasses or contact lenses, can effectively address refractive errors, and restore clear vision.

Eye Strain

Prolonged use of digital devices, reading for extended periods, or engaging in visually demanding tasks can lead to eye strain. This causes fatigue in the eye muscles and may result in blurred vision.

Dry Eyes

Insufficient tear production or poor tear quality can lead to dry eyes, causing discomfort and blurriness.


Infections, such as conjunctivitis (pink eye), or allergies can cause redness, itching, and blurred vision.

Systemic Health Conditions

Certain systemic health conditions, such as diabetes or hypertension, can impact vision and cause blurred vision.

Managing these conditions through proper medical care and lifestyle changes can help improve eye health and reduce visual disturbances.

Can dehydration cause blurred vision?

Yes, dehydration can cause temporary blurred vision. When your body lacks sufficient fluids, including in the eyes, it can affect the normal functioning of the eyes and lead to blurred vision.

Staying hydrated by drinking an adequate amount of water throughout the day can help alleviate this issue.

Does high blood pressure cause blurry vision?

Sometimes, high blood pressure can cause blurry vision, especially if it leads to damage to the blood vessels in the eyes.

If you experience persistent or sudden blurry vision along with other symptoms like headaches, dizziness, or nosebleeds, it's important to consult a healthcare professional to assess and manage your blood pressure levels.

When should you worry about blurry vision?

You should be concerned about blurry vision if it persists for an extended period, and worsens over time. Additionally, see a professional when blurred vision is accompanied by other concerning symptoms such as severe eye pain, headaches, or eye redness.

Seeking prompt medical attention is advisable to identify and address any underlying causes.

How do I know if my blurred vision is serious?

If you're unsure whether your blurred vision is serious, it's best to consult an eye care professional.

What causes sudden blurry vision?

Blurred vision that occurs suddenly can have various causes, including migraines, eye infections, injury to the eye, or even certain medications.

If you experience sudden and persistent blurry vision without an apparent cause, seek immediate medical attention to rule out any serious underlying conditions.
