Common Causes of Blurry Vision

Sudden Blurry Vision

Blurry vision in one eye or both can be a temporary annoyance or it can be a sign of an underlying issues. This comprehensive guide looks at common eye conditions and the best practices to relieve them fast.

Pinpointing the exact cause of blurry vision is the first step toward formulating an effective solution.

Refractive Errors

Refractive errors, including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, occur when the shape of the eye prevents light from focusing directly on the retina, leading to blurred vision. These vision problems are common and can be easily corrected with glasses, contact lenses, or LASIK laser surgery.

Thus, if blurry vision is what you’re dealing with, a refractive error could be the source of the problem.


Another common cause of blurry vision is cataracts, which occur when the lens of the eye becomes cloudy, impairing vision. Symptoms may include glare, difficulty seeing in low light, and faded colors.

Cataract surgery, which may involve laser treatment, is the recommended treatment, involving the removal of the cloudy lens and its replacement with an artificial one. This procedure can help restore clear vision.

Dry Eyes

Dry eyes can also lead to blurry vision as the disruption of the tear film affects the eye’s ability to focus light on the retina. Symptoms of dry eye include:

  • irritation

  • burning

  • blurred vision

  • increased sensitivity to light

Treatment options for dry eyes include artificial tears, eye drops, which can help alleviate symptoms and improve vision.

Uveitis is A Cause Of Blurry Vision in One Eye or Both Eyes

Halo Effect or Long Tails Off Lights

Uveitis is an inflammation of the uvea, the middle layer of the eye, which can lead to vision issues, pain, and redness in one or both eyes. The condition may be triggered by the body’s response to an infection or associated with certain conditions such as psoriatic arthritis or lupus.

Uveitis, causing significant discomfort and blurry vision, necessitates appropriate treatment to ease symptoms and ward off complications.

Uveitis Symptoms

Symptoms of uveitis can include:

  • Redness

  • Pain

  • Sensitivity to light

  • Blurry vision

  • Pinpoint pupil

  • Pupil is not round

  • Halo Effect around lights at night

The condition can affect one or both eyes, making it essential to identify and address the root cause to prevent vision loss.

Treatment for Uveitis typically involves the use of steroid eye drops or injections to reduce inflammation. Depending on the underlying cause, other treatments may include eyedrops, injections, and medications to dilate the pupil.

However, an awareness of the potential risks tied to steroid treatment, as discussed below, is of great importance. Educate yourself around the newer and safer alternate treatments available.

Risks of Steroid Treatment

Think twice before accepting this 70-year-old treatment option. While steroid treatment can be effective in reducing inflammation and alleviating uveitis symptoms, it can also pose potential risks. These include increased eye pressure, which may lead to glaucoma, cataract formation, and a heightened risk of infection.

Close monitoring of patients undergoing steroid treatment for uveitis is vital to managing these risks effectively.

Should blurry vision occur as a result of diabetes, contacting your healthcare provider for appropriate management and treatment is crucial.

Multiple Sclerosis

Multiple sclerosis (MS) is an autoimmune disorder where the body’s immune system attacks the optic nerve, resulting in blurry vision, pain, and color vision changes. Treatment options for MS include medications to reduce inflammation, slow the progression of the disease, and manage symptoms.

Additionally, physical therapy, occupational therapy, and lifestyle changes can help manage the visual symptoms associated with MS.

High Blood Pressure

High blood pressure can damage blood vessels in the retina, leading to vision problems and blurry vision. Proper management of high blood pressure, such as maintaining a healthy diet, exercising regularly, and taking prescribed medications, can help prevent vision issues related to high blood pressure.

If you’re experiencing blurry vision due to high blood pressure, consult your healthcare provider for proper management and treatment.

Eye Infections and Inflammation

Eye Infecions and Inflammation

Eye infections and inflammations, such as conjunctivitis, keratitis, and uveitis, can cause blurry vision and discomfort. These conditions often result from bacterial, viral, or fungal infections or allergic reactions and may require medical intervention to prevent further complications.

In this section, we’ll explore these eye infections and inflammations and their impact on vision.


Conjunctivitis, or pink eye, is an infection of the outer conjunctival membrane of the eye, causing blurry vision, redness, and discharge. Treatment for conjunctivitis depends on the cause, with antibiotics prescribed for bacterial infections, antihistamines for allergic reactions, and supportive care for viral infections.

If you suspect you have conjunctivitis, it is important to seek medical attention to prevent the spread of infection and ensure proper treatment.


Keratitis is an inflammation or infection of the cornea, causing blurry vision, pain, and light sensitivity. Treatment for keratitis depends on the underlying cause and may include antibiotic, antiviral, or antifungal medications to address the infection.

If you suspect you have keratitis, it is essential to seek medical attention to prevent further complications and ensure proper treatment.

Ocusolve Eye Wash is a reliable option for Infection control, and will require use every hour in order to eradicate the infection quickly.
