Blurred vision, as the term would suggest, typically is characterized by degrading or loss of sharp vision. But blurry vision can also be a sign of another underlying health problem. Blurry vision or double vision can affect one eye or both eyes at once and can occur at varying frequency.
Those with nearsightedness or farsightedness commonly experience blurry vision without proper corrective lenses. Blurry vision can also be a result of other concerns, ranging from dry eyes or glaucoma to migraines or retinal detachments. If you notice your vision has suddenly become blurry should contact their eye doctor immediately.
What Causes Blurred Vision?
There are many causes for blurred vision, such as:
- Nearsightedness, farsightedness or other refractive eye conditions may need corrective lenses or an updated lens prescription
- Ocular stress such as heavy computer use
- Eye conditions such as glaucoma, cataracts, presbyopia, cataracts or macular degeneration or dry eyes syndrome
- Physical head trauma such as a concussion
- Medications such as anticholinergics, antihypertensives, asychotropic drugs, cortisone, oral contraceptives, antidepressants and heart medications
Can Blurred Vision Cause Headaches, Nausea or Dizziness?
In many situations, blurred vision can be accompanied by headaches, nausea or dizziness. Some of the most common causes of blurred vision with headaches, nausea, and dizziness are the onset of migraines or the flu. But blurred vision can also signify a problem with optical nerves that trigger symptoms like headaches or dizziness.
Blurred vision can be the result of many underlying issues. You should have your situation diagnosed by your optometrist.
Can Blurred Vision Go Away?
It depends on the cause of the blurred vision. Often sudden blurred vision can be brought on by intense reading or too much computer use at work. Stress can also bring about sudden blurred vision. In these cases, blurred vision is usually temporary and can subside within a few hours.
In other cases, such as blurred vision caused by underlying eye conditions or other health concerns like diabetes, disrupted perception may persist longer and requires the attention of your optometrist.
Can Blurred Vision Be Corrected or Reversed? Does Blurred Vision Mean I Need Glasses?
Blurred vision can be caused by a wide variety of factors, some of which may be able to be treated or corrected with prescription glasses. Anyone experiencing sudden blurred vision that persists for more than 2-3 hours should talk to his or her trusted eye doctor.
Your eye doctor can perform tests to determine the cause of your blurred vision and prescribe the proper treatment. For more information about blurred vision, call for an eye exam today!
