What is Blurring of vision?

Blurred vision refers to a lack of clarity of vision that results in an inability to see fine details. Blurred vision can result from abnormalities such as myopia, hyperopia, presbyopia, or astigmatism that can be improved with corrective lenses or signal the presence of an eye condition. Blurry vision can be felt in one eye or both eyes, depending on the cause. Blurry vision can also be a symptom of many conditions that do not directly affect the eye, such as migraine or stroke. Several medications can also cause temporary blurring of vision as a side effect. Sometimes the blurred vision is associated with other symptoms, depending on its cause, including headache, sensitivity to light, or redness and irritation of the eyes.

Causes:

Conditions requiring immediate assessment and treatment:

Detached retina:

A detached retina is when your retina pulls away from the back of your eye and loses blood and nerves.
When this happens, you see flashing lights and black spots followed by an area of blurry or no vision. Without emergency treatment, vision in this area can be permanently lost.

Stroke:

Blurred or lost vision in both eyes can occur when you experience a stroke affecting the part of the brain that controls vision. A stroke affecting your eye causes blurry or lost vision in one eye.
You may have other symptoms of a stroke, such as weakness on one side of your body or an inability to speak.

Transient ischemic attack:

Transient ischemia (TIA) is a stroke of fewer than 24 hours. One of its symptoms may be a blurred vision in one or both eyes.

Wet macular degeneration:

The center of your retina is referred to as the macula. Abnormal vessels can develop, causing blood and other fluids to leak into the macula. This is called wet macular degeneration.
This causes blurring and loss of vision in the central part of your visual field. Unlike dry macular degeneration, this type can start suddenly and progress quickly.

Angle-closure glaucoma:

Closed-angle glaucoma occurs when the drainage system in the eye is blocked. In this situation, the pressure inside the eye can build up very quickly, causing redness, pain, and nausea.
This is a medical emergency and requires treatment with eye drops to open the angle, decrease pressure, and decrease inflammation. In many cases, a laser procedure, known as laser iridotomy, is also required.

Other causes of sudden blurred vision:

Eye fatigue:

Eye strain can occur after looking and focusing on something for a long time without interruption.
When it comes to focusing on an electronic device like a computer or cell phone, it is sometimes referred to as digital eye strain. Other causes include reading and driving, especially at night and in bad weather.

Conjunctivitis:

Also called pink eye, conjunctivitis is an infection of the outer wall of the eye. It is usually caused by a virus, but can also be caused by bacteria or allergies.

Corneal abrasion:

Your cornea is the clear coating in the front of your eye. When scratched or injured, you can develop corneal abrasion. In addition to blurred vision, you may feel like there is something in your eyes.

High blood sugar:

Very high blood sugar causes swelling of the lens which leads to blurred vision.

Hyphema:

The dark red blood that collects in the front of your eyeball is called hyphema. It is caused by bleeding that occurs after an eye injury. This may cause pain if it increases the pressure inside the eye.

Iritis:

Iris is a colored part of your eye. Iris occurs when an autoimmune reaction or infection causes inflammation of the iris.
It can occur on its own or as part of an autoimmune disease, such as rheumatoid arthritis or sarcoidosis. It can also be caused by infections like herpes.
It may cause pain and sensitivity to light, also known as photophobia.

Keratitis:

Inflammation of the cornea is called keratitis. It is usually caused by an infection. Using a pair of contacts for too long or reusing dirty contacts increases your risk for it.

Macular hole:

The macula is the center of your retina, which is responsible for your central vision. It can develop a tear or break that causes blurred vision. It usually only affects one eye.

Migraine with aura:

Migraine attacks are often preceded by an aura which can cause blurred vision. You can also see wavy lines or flickering lights and have other sensory disturbances. Sometimes you can have an aura without pain in your head.

Optic neuritis:

The optical nerve connects your eye with your brain. Optic nerve inflammation is also known as optical neuritis.
It is usually caused by an autoimmune reaction or early multiple sclerosis. Other causes are autoimmune diseases, such as lupus or infection. It usually only affects one eye.

Temporal arteritis:

Inflammation of medium-sized arteries is called temporal arteritis. The vessels around your temples can be involved, causing a throbbing headache in your forehead, but it can also make your vision blurry or go away.

Uveitis:

The uvea is a group of pigmented structures within the eye, including the iris. An infection or autoimmune reaction can cause inflammation and pain, which is called uveitis.

Diagnosis:

Your doctor will diagnose the cause of your blurred vision by first taking a look at your signs. Examples of questions they can ask:

When did you first notice the blurred vision?
What makes blurred vision worse or better?

The physician may also ask about your personal medical history as well as a family history of eye conditions.

Eye tests:

Your physician may then want to examine your eyes. They can test your vision by asking you to read an eye chart. They may also perform other eye tests, such as:

ophthalmoscopy
refraction test
slit-lamp examination
tonometry, which measures intraocular pressure

Blood tests:

Your doctor may also perform blood tests. Blood tests can be used to help them determine if bacteria are present in the blood. They may also use tests to get your white blood cell count (WBC) if they suspect there might be an infection.

Treatment:

The treatment will depend on the condition of your sight.

Detached or torn retina: This requires emergency surgical repair to prevent irreversible vision loss.
Stroke: Timely and appropriate treatment for the type of stroke you are having is essential to prevent the death of your brain cells.
Transient ischemic attack: Symptoms go away on their own within 24 hours. You may be given blood thinners to reduce the risk of stroke in the future.
Wet macular degeneration: Medicines injected into the eye can help improve vision. Laser photocoagulation treatment can slow vision loss but cannot restore your vision. Special vision enhancement devices are sometimes used to improve your vision.
Eye strain: If your eyes are tired, pause, and rest your eyes. One thing you can do to prevent it is to follow the 20-20-20 rule. To do this, focus on something 20 feet away for 20 seconds every 20 minutes when looking at a screen or something for a long time.
Conjunctivitis: Usually goes away on its own, but antibiotics or antiviral drugs can often speed healing and reduce the risk of spreading.
Corneal abrasion: This usually heals on its own within a few days. Antibiotics can treat or prevent infection.
High blood sugar: Lowering blood sugar will fix the problem.
Hyphema: When there are no other injuries and your eye pressure is not increased, bed rest and an eye patch should help. If it is more severe and the pressure is very high, your ophthalmologist may have the blood removed surgically.
Iritis: It generally cures completely on its own or with steroids. However, it recurs frequently. If it becomes chronic and resistant to treatment, you may lose your sight and immunomodulatory drugs may be needed to prevent this.
Keratitis: When caused by infection, keratitis is treated with antibiotic drops. For severe infection, oral antibiotics and steroid eye drops may be used.
Macular hole: If it does not heal on its own, surgical repair of the hole is usually done.
Migraine with aura: An aura does not need treatment, but it is a signal that you need to take your usual medicine for your migraine.
Optic neuritis: This is managed by treating the underlying disease, but steroids can be helpful even if there are no systemic signs.
Temporal arteritis: It is treated with long-term steroids. Treatment is important to prevent permanent vision issues.
Uveitis: Uveitis like iritis, resolves spontaneously or with steroids. Repeated recurrence can lead to resistance to treatment and, potentially, blindness.

When to visit a Doctor?

You should call or see the local emergency services and get immediate medical attention if your blurred vision suddenly appears and you experience any of these symptoms:
You should consult the physician as soon as possible if:

Severe headache
Difficulty speaking
Loss of muscular control on either side of the body
Falling face
Difficulty seeing

These signs are similar to those of stroke.
Other symptoms that may require immediate attention include severe eye pain or sudden vision loss.
Slow-onset vision or other blurred vision symptoms may require a visit with your primary care physician or eye care specialist.

Home Remedies:

Eye exercises:

In most cases, visual blurring occurs with aging. It is better to opt for eye exercises before the blur gets worse or leads to serious illness. Simple eye exercises can help you maintain optimal vision.
Warm your eyes regularly by rubbing your hands together and then placing them over your eyes for 5-10 seconds. Repeat this three times for each session.
Rolling the eyes is another way of calming the eyes. Roll the eyes 10 times, both clockwise and counterclockwise. It is recommended to do this exercise with the eyelids closed.
Focusing exercises such as pen push-ups can also help achieve a clearer vision and even naturally improve eye vision.

Rest, repair, and recovery:

Human eyes are sensitive, which is why they require more rest than any other external organ. Providing the eyes with sufficient rest for the day would improve your vision.
Getting decent sleep is one of the important things you need to remember. Getting deep sleep for about 8 hours a day would allow your eyes to rest, repair, and recover.
If you suffer from blurry eyesight, you should schedule an hourly eye break at your workplace. Or if you love to read or surf the computer, be sure to rest your eyes for 10 minutes every 50 minutes until you get tired of your eyes.
If you feel that your eyes are too tired, always remember a rule of thumb for eye relaxation. Place cold cucumber slices on your eyelids. It would soothe your eyes in the best possible way.

Avoid triggers:

When you suffer from temporary blurred vision, you need to identify triggers and avoid them. Anxiety, stress, migraines, and health issues are some common triggers for blurred vision.
Getting decent sleep is one of the important things you need to remember. Getting deep sleep for about 8 hours a day would allow your eyes to rest, repair, and recover.
Try to keep track of your pain and migraines. Sometimes migraines are accompanied by a blurring of vision, so identifying the triggers for your headaches can also help reduce visual disturbances.
To manage stress and reduce anxiety, you can do meditation or aromatherapy. Joining support groups or even talking to a psychotherapist or anxiety coach can also be helpful.

Frequently Asked Questions:

Why is my vision suddenly blurry?

Blurry vision is very common. A problem with any component of your eye, such as the cornea, retina, or optic nerve, can cause sudden blurred vision. Blurred vision is usually due to long-term medical problems. Sudden blurring is most often the result of a single event.

Can blurry vision go away?

If you have blurry vision, you may attribute it to age or need new glasses. But it may also be a sign of other medical conditions. Often, treating these conditions will clear up your blurry vision.

Why does my vision get blurry after looking at my phone?

Increased interaction with digital displays has resulted in Computer Vision Syndrome (CVS), which damages vision and causes vision problems. Some symptoms of this disorder are blurred vision, tired eyes, headache, neck pain, and dry eyes.

Why does my vision suddenly go white?

A grey-out is a transient vision loss characterized by the perceived attenuation of light and color, sometimes accompanied by peripheral vision loss. It is a precursor to fainting or a power outage and is caused by hypoxia (low oxygen levels in the brain), often due to a loss of blood pressure.

Is cloudy vision serious?

Blurry vision and blurred vision can sometimes be accompanied by symptoms such as headaches, eye pain, and halos around lights. Some conditions that cause blurry or cloudy vision can lead to vision loss if left untreated.
