What Causes Sudden Blurred Vision?

Blurred vision can signify serious eye injuries, such as a penetrating object or chemical burn. Deep scrapes or a painful incident can also lead to blurred vision. While some causes of blurred vision are treatable, many are not. Treatment depends on the cause of the blurred vision and the severity of the condition. Read on to learn more about common eye injury causes and the proper treatment.


Iritis is an inflammation of the colored part of the eye. It can lead to a variety of complications, including cataracts and glaucoma. In addition, the inflammation may lead to changes in the cornea and secondary inflammation of the retina. Treatment for iritis depends on the underlying cause. Your healthcare provider will determine the proper medication for your particular case and work with you to find a treatment plan.

The most common treatment for iritis involves steroid eye drops, tablets, or injections. However, steroid eye drops can increase eye pressure and permanently impair vision. Over time, the use of drops can lead to cataracts. Iritis is also a risk factor for macular edema, which causes swelling in the central retina. In some cases, it can be life-threatening if untreated. The key to successful treatment is identifying the condition early and starting treatment early.


The treatment for conjunctivitis, also known as pink eye, varies according to the cause. If the cause is a viral infection, antibiotics are often prescribed to help the affected eye recover faster. If an allergy causes the problem, steroid eye drops are also used to minimize the spread of the infection. Other treatments may include vision therapy, or saline eye drops to reduce the amount of eye swelling.

The sudden blurry vision can be caused by various factors, including a prolonged focus on an object, excessive screen time, and driving in poor visibility. It is essential to seek medical care as blurred vision Halifax can indicate severe eye conditions such as retinal detachment, corneal abrasion, or stroke. Fortunately, most eye conditions are treatable with an eye exam by a trustworthy optometrist. In addition, some people experience sudden blurry vision due to a virus, bacteria, or allergies.


Glaucoma causes many different causes, including blunt eye injury, chemical exposure, and severe eye infections. It can also be caused by blocked blood vessels in the eye and eye surgery to treat another condition. This disease usually affects both eyes and can even affect infants. African Americans and Hispanics are at higher risk of glaucoma than other races, and people with thin corneas are more likely to develop the disease. Another risk factor is chronic eye inflammation, which can increase pressure in the eye.

If your parent is experiencing sudden, recurring blurry vision, you should get screened for this condition, as early detection and treatment are crucial to keeping their sight. Your parent will need to take eye drops as prescribed by their doctor. Eye drops can be difficult for elderly or physically impaired people to remember to put them in. If your parent struggles to remember to take these drops, ask a family member to remind them or call them. In addition, be sure to keep in touch with your parent’s doctor and follow the recommended treatment plan.

Age-related macular degeneration

Macular degeneration affects the macula, the part of the retina responsible for detecting detail. When this area becomes damaged, abnormal blood vessels form on it and interfere with the macula’s function. These abnormal blood vessels grow in people over the age of 50. This condition is often characterized by sudden, hazy, or blurry vision. Sometimes it causes localized spots of blurred vision. Unlike dry AMD, it can progress quickly.

The best way to tell if you have age-related macular degeneration is to undergo a thorough eye exam with a neurologist. Your doctor will perform a visual acuity test to see how you can see at various distances. They may also perform pupil dilation, which widens the pupil so that the retina can be examined closely. Another test to diagnose age-related macular degeneration is fluorescein angiography. Fluorescein angiography involves injecting a dye into your arm to take pictures of the blood vessels in your retina. Fluorescein angiography can also diagnose wet age-related macular degeneration.


Many people with chronic fatigue syndrome (CFS) experience symptoms such as blurry vision. This is due to a malfunction in the brain. Because the brain is not functioning correctly, signals from the eyes may not reach the eye. As a result, patients with CFS often experience periods of foggy or blurred vision that are particularly noticeable when standing up. Peter Rowe, director of the Chronic Fatigue Clinic at the Johns Hopkins Children’s Center in Baltimore, says that this condition can also cause vision problems such as headaches, sensitivity to light, and dizziness.

Many of these symptoms are startling. Some people experience dizziness or lightheadedness, which can indicate a severe problem. For those who share sudden blurry vision, seeking medical attention is imperative. If left untreated, it could be a symptom of multiple sclerosis. However, if the symptoms occur slowly and are not severe, they’re usually easily treatable.
