I was wondering this when I touched my bare eye (my eye was open) and since I'm not blind I was wondering if an eye is blind, can it still feel pain?

Blindness can be due to a damage of the lens, retina, optic nerve or the visual area at the occipital lobe of the brain, for example.

Sensitivity of the eye cornea is enabled by a different nerve - the ophthalmic nerve, which is a branch of the trigeminal nerve (Yale Journal of Biology and Medicine). As long as this nerve, somatosensory cortex at the parietal lobe of the brain and other neural structures involved in pain sensation are intact, you should be able to feel pain when touching the cornea of the blind eye.

Eye Care Warning Signs You Don't Want To Ignore

Perhaps the most beautiful of all the senses is the gift of vision. Being able to see the face of one's children, spouse, family members, and friends is simply amazing. Enjoying the views of Mother Nature's trees, waterfalls, and even majestic mountains are all delightful. What would a world of darkness be like a world where one had to feel their way around and couldn't see anything but blackness? Too many individuals have lost their vision because they didn't realize the warning signs and get help.

Here are common symptoms and conditions that occur in the eyes that warrant an eye examination. None of them should be ignored!

Pressure Or Pain In The Eyes

One of the most common reasons why individuals may experience pressure or pain in the eyes is to do with their sinuses. The eyes are surrounded by sinus cavities, and when the sinuses fill they will put pressure on the eyes, which may also cause the eyes to run or get a little red. Another issue involved with the eyes that may result in pain or pressure is glaucoma, a condition that occurs when pressure builds up inside the eye. The result is damage to the eye's optic nerve and eventually blindness. Most eye doctors test for this in a routine examination, though it is important for patients to remember to ask, especially if their family has a history of it, as glaucoma is quite serious.

Pain in the eyes can also be caused by headaches. Migraines are especially notorious for causing the eyes to ache. Some individuals even say they can feel a migraine beginning because it starts in the eyes first. Any severe pressure or pain that feels like a stabbing knife or causes vision to be distorted needs to be evaluated right away.

The eye is about eighty percent full of a gel-like substance called the vitreous. This gel helps the eye maintain its nice round shape. However over time, the gel begins to slowly shrink, and as this substance begins to shrink, it will make strings and dots (floaters) that will cast a shadow onto the retina. They are completely harmless if they are caused by the vitreous, but only a doctor can determine if it is a benign floater or other problem.

While floaters caused by gel-like substances are not a sight-threatening condition, a retinal tear, which can cause a similar effect, is. Consequently, many with floaters caused by retina tears warn of increased floaters in a short period, or even some darkness in their vision, which is why floaters need to be evaluated. They can be serious and not a floater at all but rather a tear. The spots and strings seen may also be caused by a bleed in the eye. Blood can get into the vitreous and cause the strings and dots thought to be floaters. However, it can be blood vessels leaking down into the eyes. This is equally a dangerous problem and needs to be addressed.

Keep reading to learn more about what warning signs related to the eyes everyone should pay attention to now.

Flashing Lights

Flashing lights sometimes accompany floaters in the eyes. It can be as simple as some light reflecting off the vitreous, which has begun to break down. Some individuals who have seizure disorders often see flashes of light before a seizure occurs. This is called an aura, a phenomenon that happens to give the patient a warning something is about to happen. Those who have epilepsy may see this each time before a seizure, or they may not experience them at all. If there is trauma to the brain in any way, it is not uncommon to see these flashing lights too.

Another problem often behind flashes of light is a stroke. Many stroke patients state that they see flashing or zigzag lines in their vision field before the stroke. Again, it is a warning sign something is not right. It is hard to determine if the flashes of light are harmless or cause for concern. The best thing to do is to contact a doctor and have them evaluate the flashes.

Blurry Vision

There are quite a lot of reasons why an individual's vision might be blurry. However, the most common form of blurry vision is what comes with the need for corrective lenses. When someone experiences blurry vision, along with conditions like nearsightedness or farsightedness, they will often need to have their eyes examined and fitted with a prescription for contacts or glasses so their vision can be appropriately corrected. Diabetes can also cause an individual's vision to blur if they have high blood sugar. Unfortunately, diabetes quite commonly causes blindness. If an individual has diabetes and their vision is blurred, this is a good indication their blood sugar is not being controlled properly. It is also a sign an individual with prediabetes is now a full diabetes patient, though only a doctor can make this determination. Migraines and a stroke can also result in blurry vision, so it's important to get sudden, intense, and painful blurry vision checked out as soon as possible.

Sensitivity To Light

Light sensitivity, also called photophobia, can occur by itself or a part of a series of symptoms. Some of the most common reasons for light sensitivity are pink eye, sinus issues, and even headaches. However, several diseases carry light sensitivity as a symptom. Autoimmune conditions such as rheumatoid arthritis and Sjogren's syndrome are known for making the eyes very sensitive. Other conditions to be concerned about are mononucleosis, sarcoidosis, and encephalitis, as they also cause light sensitivity fairly often. A subarachnoid hemorrhage (SAH) is a bleed that takes place in the subarachnoid space, which is where the cerebrospinal fluid circulates. An injury to this area can cause a coma, light sensitivity, paralysis, and even death.

Issues Seeing At Night

An individual may notice they have more trouble than usual with being able to see clearly at night or in poor lighting conditions. Often referred to as nyctalopia, this problem is the result of an individual's eyes having an inability to adjust to low-light conditions properly. Several different problems with an individual's eyes can cause them to have issues seeing at night. Cataracts can cause the light an individual is looking at to become distorted and create halos. An individual who is having issues with seeing at night may have a deficiency of vitamin A or zinc. Vitamin A helps keep an individual's retina in good health but is unable to be utilized by their body for this purpose without enough zinc. An individual who experiences difficulty seeing clearly at night who is under thirty years old may be affected by retinal damage due to a serious genetic disorder referred to as retinitis pigmentosa. A diabetes patient who experiences issues with seeing at night may be affected by diabetic retinopathy and should seek immediate treatment.

Red Eyes

Red eye describes when the white of an individual's eye appears red or looks bloodshot. The manifestation of red eyes in an individual that is short-lived and resolves on its own is not concerning. However, an individual who experiences red eyes that do not resolve after a week or occur along with other symptoms may have a more serious underlying eye condition. Infections in different parts of the eye are known to produce persistent red eyes and require medical treatment to avoid permanent damage to the affected structures. Red eyes that do not resolve following any kind of injury or trauma to an affected individual's eye require urgent medical treatment to ensure there is not a bleed in the eye. Acute glaucoma or the rapid increase of internal pressure of the eye can also produce red eyes in an individual. This is often accompanied by pain and needs emergency treatment to prevent further vision loss. Other causes of red eyes can include bleeding disorders, rheumatoid arthritis, scleritis, and contact lens overuse.

Unusually Teary Eyes

A healthy individual experiences teary eyes or watery eyes in response to environmental factors and irritants because it is a mechanism used to keep foreign particles out of the eyes and keep the eyes healthy. However, teary or watery eyes that are disruptive to everyday activities and constant are not a normal response. Unusually teary eyes can be the result of an overproduction of tears by the ducts in the eyes because of an injury or structural abnormality. Ectropion is a term used to describe when an individual's lower eyelid turns outward and produces abnormally teary eyes. An individual who has abnormally watery eyes may be affected by trichiasis, a condition where the eyelashes grow inward toward the eye instead of out and away from the eye. Other serious causes of unusually teary eyes include keratitis, corneal ulcers, Bell's palsy, and Meibomian glands. It is important to seek treatment for conditions that cause abnormally teary eyes because many of them have the potential to produce permanent vision damage when left untreated.

Faded Colors

An individual who is affected by certain eye conditions may experience the manifestation of faded colors in their vision. Faded color in the visual field refers to when an individual has a decreased ability to distinguish one color from another. Faded colors are often a sign of cataracts, which is the development of a cloudy film in the lens of the eye. Cataracts develop when an injury or the natural process of aging causes alterations in the tissue that makes up the lens of an individual's eye. Faded colors in the vision should not be ignored when caused by cataracts because of the danger declining vision poses when an individual is driving a vehicle, operating machinery, and performing other tasks. Other serious but rare causes of faded colors in an individual's vision that may not be isolated to the eye include sickle cell anemia, macular degeneration, multiple sclerosis, Parkinson's disease, leukemia, diabetes, Alzheimer's disease, and glaucoma.

Blank Spots In Central Vision

An individual who has blank spots in their central vision or what is commonly referred to as floaters should seek care from their ophthalmologist. Floaters are spots or shadows that appear in an individual's field of vision. Blank spots in the central vision can be a variety of different shapes and sizes. The blank spots in an affected individual's vision can be very bright, very dark, flickering, or blurry. Floaters in the central vision may make it difficult for the affected individual to make out certain colors. Some individuals affected by blank spots require a bright source of light to see clearly. It is normal for an individual to see floaters in their vision every once in a while, but a sudden increase in the frequency of floaters can indicate a serious underlying condition. Blank spots in an individual's vision can indicate damage has occurred in the retina, they are bleeding inside of the eye, the onset of a stroke, the presence of a tumor, glaucoma, optic nerve damage, or vitreous inflammation.

What can cause sharp pain in the eye?

Sharp eye pain can stem from many causes. Without treatment, some of these issues can lead to vision loss and other serious complications.

Intense or sharp pain often results from debris entering the eye.

This type of pain can also occur with migraine or cluster headaches. In some cases, inflammation or fluid buildup in the eye can also lead to severe pain, as well as tissue damage and vision problems.

In this article, we discuss seven causes of sharp eye pain and when to see a doctor.

Share on Pinterest If debris becomes lodged in the eye, it may cause a sharp pain.

1. Debris in the eye

Many people experience sharp pain when debris, such as dirt or dust, becomes lodged in an eye.

The pain usually subsides once a person flushes the debris from their eye. They can do this by splashing water or saline solution on the affected eye.

If a person continues to experience eye pain, they may have a corneal abrasion, which is a small scratch on the eye. In this case, it is best to contact an optometrist or ophthalmologist for further evaluation.

2. Uveitis

Uveitis is inflammation of the eye’s middle layer — the uvea.

This inflammation can also affect the eye’s lens, retina, optic nerve, and vitreous fluid. It can occur in one or both eyes.

Uveitis can cause the following symptoms:

  • eye pain and redness
  • dark spots in the vision
  • blurred vision
  • sensitivity to light

Uveitis can damage tissue in the eye, which may result in reduced vision or vision loss.

Medical professionals who specialize in eye health can use chart exams and evaluate the pressure inside the affected eye to diagnose uveitis. They may also dilate the pupil to inspect the back of the eye.

Treatments for uveitis focus on reducing inflammation and pain, preventing tissue damage, and counteracting vision loss. A doctor may recommend:

  • corticosteroid injections or drops
  • oral immunosuppressive medication
  • anti-inflammatory eye drops or oral medication

3. Scleritis

Scleritis is severe inflammation of the sclera — the outermost membrane of the eye.

People can develop scleritis as a result of an infection or autoimmune disease, or as a side effect of medication. In some cases, doctors cannot identify the cause.

A person with scleritis may experience mild-to-severe eye pain that gets worse at night or with eye movement. Other symptoms include:

Doctors may perform multiple tests to diagnose scleritis. These include:

  • imaging tests, such as X-rays, MRI scans, and CT scans
  • antibody tests
  • a complete blood count
  • tests for Lyme disease or rheumatoid arthritis

The right treatment will depend on the underlying cause of scleritis, as well as the type and severity of symptoms.

  • corticosteroid eye drops, oral tablets, or injections
  • nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen
  • immunosuppressive medications
  • biologics, including infliximab and rituximab

4. Cluster headaches

Cluster headaches can cause severe pain. People often describe the pain as searing, burning, or stabbing, and it tends to occur above the eye or near the temple.

In this context, a “cluster” refers to a group of headaches. They usually occur during the day, and one cluster commonly lasts from 15 minutes to 2 hours.

Clusters may occur frequently for several days or weeks, with pain-free periods in between.

  • intense pain on one side of the head
  • red or watery eyes
  • a runny or stuffy nose
  • pupil constriction
  • drooping eyelids
  • sweating
  • restlessness or agitation

5. Migraine

Migraine is a common neurological disease that can cause headaches and episodes of other symptoms. It affects about 29.5 million people in the United States .

A migraine headache can cause severe, throbbing pain behind one or both eyes, and a person may also experience:

  • sensitivity to light and sound
  • vision changes, such as seeing flashing lights or partial vision loss
  • dizziness
  • loss of coordination
  • weakness
  • nausea and vomiting
  • mood changes
  • confusion
  • difficulty concentrating

Symptoms of a migraine headache or episode typically last for 4–72 hours.

Doctors and researchers still do not fully understand what causes migraine. However, certain factors can trigger symptoms. Among them are:

  • emotional triggers, including stress or anxiety
  • physical stress, due to lack of sleep, poor posture, or overexertion
  • certain foods, such as chocolate, aged cheeses, and processed meats
  • beverages that contain alcohol or caffeine
  • hormonal changes, such as those that occur during menstruation or menopause
  • overuse of certain medications, such as over-the-counter pain relievers

6. Angle-closure glaucoma

Glaucoma is a group of diseases that damage the optic nerve. Without treatment, glaucoma can cause vision loss and blindness.

There are three types of glaucoma: open-angle, normal-tension, and angle-closure.

In the U.S., open-angle glaucoma is the most common form, and most people who have it do not experience symptoms right away.

Angle-closure glaucoma occurs when fluid quickly builds up in the front of the eye, causing a sudden increase in pressure and intense eye pain. Another name for this disease is narrow-angle glaucoma.

  • a sudden, severe headache
  • nausea
  • blurred vision
  • seeing halos around bright lights

The symptoms of angle-closure glaucoma develop rapidly.

This condition is a medical emergency that requires immediate treatment. A doctor can drain the excess fluid and prescribe medication that reduces the pressure in the eye.

7. Tolosa-Hunt syndrome

Tolosa-Hunt syndrome is a rare medical condition that causes sudden, severe eye pain.

It usually affects one eye, and moving the eye may be particularly painful. Some people also experience temporary paralysis in the eye.

The symptoms of Tolosa-Hunt syndrome often clear up without medical intervention and recur sporadically.

The exact cause of the syndrome remains unknown. However, some researchers believe that it arises from the inflammation of certain areas behind the eye and that this relates to an abnormal autoimmune response.

Severe or persistent eye pain can indicate an underlying medical condition, such as uveitis, scleritis, or angle-closure glaucoma.

A person should contact an ophthalmologist or their regular doctor if they have:

  • severe eye pain
  • eye pain that does not go away after a few hours
  • visual disturbances, such as blurred vision or dark spots
  • visible swelling of the eye or nearby tissues
  • nausea or vomiting

Sharp pain in the eye can cause significant discomfort. Depending on the cause, the pain may resolve without treatment, or the issue may require medical intervention.

A person should contact a doctor if they experience severe eye pain or any eye pain that lasts for more than a few hours, as these symptoms can indicate a more serious underlying condition.

Many causes of sharp eye pain are treatable. A doctor will often focus on reducing inflammation and pain, preventing tissue damage, and recovering any loss of vision.

If This Part of Your Body Hurts, You Could Have COVID

Experts say that the underreported symptom affects a significant number of COVID patients.


While some symptoms of COVID have been widely reported, like fever, a dry cough, and fatigue, they're far from the only signs you've contracted the virus. COVID can affect everything from your gastrointestinal tract to your taste buds, but according to new research, it can also cause pain in one specific part of your body that may surprise you.

According to a review of research published in the journal PLOS One recently, ocular symptoms affect 11.6 percent of COVID patients, with eye pain reported as the most common symptom, affecting 31.2 percent of patients with symptoms related to the eye. However, eye pain was just one of a long list of ocular symptoms related to COVID.

When Is Glaucoma Painful?

Angle-Closure Glaucoma

When patients have an acute angle-closure glaucoma attack, they experience pain.

The eye pain can be severe, and may cause headache, and even nausea or vomiting.

In an acute angle-closure glaucoma attack, the eye pressure rises rapidly, causing pain, and also causes the cornea to become cloudy, thus patients also notice their vision has decreased.

This is a medical emergency requiring immediate treatment. Otherwise, permanent damage and possibly blindness can result.

This acute angle-closure attack is relieved by lowering the eye pressure with medications and performing a laser iridotomy, which creates a microscopic hole in the iris using the light from a laser. The opening allows the reduction of fluid build-up and reduces eye pressure. Note that in some situations an ophthalmologist may recommend removing cataracts as part of the treatment of an angle-closure attack.

Once the attack is relieved the pain typically begins to resolve immediately, although it may still take some time for the eye to become completely pain-free.

“Secondary” Glaucomas

In addition to this type of acute angle-closure attack described above, there are also secondary forms of angle-closure glaucoma that can be painful. One of these forms is neovascular glaucoma, often related to diabetic retinopathy or retinal vessel occlusions (blockages).

In neovascular glaucoma, the drainage angle gradually closes because of new blood vessels that grow on the iris and in the drainage angle. Eventually, the entire drainage angle is blocked off and the eye pressure becomes very high, thus leading to eye pain.

In this situation, the treatment is often surgical, because medications alone cannot lower the eye pressure enough. Another important component is to treat the underlying disease leading to the growth of new vessels, such as diabetic retinopathy. Once treated, neovascular glaucoma is not usually painful in the long term.

Another form of glaucoma that can be painful is uveitic glaucoma, which is a secondary form of glaucoma related to uveitis, or inflammation of the eye. Often times the uveitis itself causes a red, painful eye even if the eye pressure is not elevated. In addition, the inflammation in the eye can lead to debris clogging the drainage angle and a rise in eye pressure, leading to pain. Over time, the uveitis can also cause scarring in the angle that can also result in increasing eye pressure. Once the uveitis and glaucoma are treated, the pain resolves.

Light Sensitivity Treatment

For mild cases of light sensitivity, you can reduce discomfort by staying out of sunlight or wearing protective (polarized) eyewear. You can also keep inside lights dimmed as necessary.

Severe or uncontrollable light sensitivity needs to be treated by your doctor. They will perform an eye exam as well as a physical exam to identify the cause. The treatment will depend on the underlying cause, and can include:

&diams Medicated eye drops for inflammatory-related causes
&diams Medications for migraines
&diams Antibiotics for infections
&diams Eye drops for corneal abrasions
&diams Artificial tears for dry eyes
&diams Surgery for brain hemorrhage to remove excess blood and pressure

Natural Treatment for Light Sensitivity

In addition to the above treatment options, you can boost eye health naturally. There are several important nutrients that protect the eyes and reduce the risk of diseases. In doing so, you can prevent light sensitivity.

Some eye conditions cannot be cured, but these natural options can protect your eyes from further damage. They can reduce symptoms like light sensitivity and pain.

To reduce inflammation that causes dry eyes, pain, and light sensitivity, consider the following natural treatments.

&diams Lyc-O-Mato®: This has been proven to reduce blood pressure and inflammation in the eye. This reduces swelling and pain, which can trigger light sensitivity. The antioxidant protection of this ingredient also reduces the risk of macular degeneration or can slow its progression.

&diams Mixed carotenes: The combined antioxidant protection of carotenes gives your eyes full coverage. Each has its own benefits, and together, this mixture can reduce the severity of symptoms associated with cataracts and glaucoma.

Cataracts are the most common eye condition in the United States. To reduce the severity of symptoms like light sensitivity, include these compounds as part of a regular eye health routine.

&diams Tocopherols are an optimized form of vitamin E. It&rsquos easily absorbed and used directly in the eye, which helps to stimulate the production of natural eye enzymes. As a result, the eye is protected from oxidative stress that can cause light sensitivity.

&diams Lutein is one of the most important eye nutrients. It protects against cataracts, glaucoma, and macular degeneration.

&diams Zeaxanthin works together with lutein. Both are found naturally in the retina of the eye. The protect this area from oxidative stress. As a result, the risk of eye disease is reduced, and light sensitivity can be treated.

Blurred Vision in One Eye

Blurred vision in one eye is a loss of vision that affects a single eye. Blurred vision can occur due to several different conditions ranging from minor to severe.

Depending on the cause, blurry vision in one eye may affect a person’s ability to make out objects at a specific distance or any distance.

Common Causes of Blurred Vision In One Eye

There are many common causes of blurry vision in one eye. Blurred vision in one eye may indicate disorders in the brain or central nervous systems, like headaches or optic neuritis.

Some common causes of blurred vision in one eye include:

Refractive errors

Refractive errors include astigmatism, nearsightedness (myopia) and farsightedness (hyperopia). These are some of the most common eye problems that cause blurred vision in one eye.

Corneal abrasion

Corneal abrasion refers to trauma to the eye. This can occur through injury from a foreign object.

Retinal detachment

If your retina tears from the back of your eye it will lose its nerve and blood supply. You'll see black flecks (floaters) followed by blurred or absent vision.


Some medicines can lead to blurred vision in one eye. However, they would usually affect both eyes.

Diabetes (diabetic retinopathy)

Diabetes can lead to cataract or retinal conditions that result in blurred vision.

Age-Related Macular Degeneration

Age-related macular degeneration (AMD) is an eye disease that causes a loss of vision in the macula. This is the part of the retina responsible for noticing detail in the central vision.


Cataracts is the loss of transparency or clouding in the lens of the eye.

Dry eyes

Dry eyes can lead to blurry sight issues.


Conditions that occur in the brain, like migraines, can lead to the blurriness of the eyes.


Presbyopia is age-related farsightedness. Typically, presbyopia causes blurred vision up close in both eyes, but may be more pronounced in one eye if you have different refractive errors in each eye.


Otherwise known as pink eye, conjunctivitis is an eye infection that causes inflammation of the conjunctiva. This is the thin and transparent membrane that is the white part of the eye.

Eye strain

Eye strain occurs when eyes become tired from excessive use. This includes driving a car for long periods, working on the computer for a while, or reading for an extended time.


Preeclampsia refers to the high blood pressure and symptoms of liver or kidney damage that women experience after the 20th week of pregnancy. In rare cases, women can experience preeclampsia after giving birth. This is usually within 48 hours.

Giant cell (Temporal) arteritis

Giant cell arteritis is a type of vasculitis. This is the inflammation of the blood vessels. In giant cell arteritis, the blood vessels found near the temples are swollen and constricted. This condition typically affects people over the age of 50.


Keratitis is an inflammatory condition that affects your cornea. Keratitis is usually the result of eye injury, disease, infection, or wearing contact lenses for too long.


Psoriasis is an immune system health issue. Triggers include stress, infections, and a cold. The most common sign of psoriasis is a scaly rash on the skin.


Uveitis is the inflammation of the middle layer of the eye. It is found between the sclera and retina. It affects the iris, ciliary body, the pars plana, and the choroid. It can sometimes also affect the retina.

Serious or Life-Threatening Causes of Blurred Vision In One Eye

In severe cases, blurry vision in one eye may indicate a severe or life-threatening condition that must be immediately evaluated in an emergency medical setting.

  • Brain tumor. A brain tumor located in the temporal lobe, occipital lobe, or brain stem can cause vision problems. The most common is blurred or double vision.
  • Stroke. A stroke involving your eye causes blurry or loss of vision in only one eye. Other symptoms of a stroke may also occur. These include weakness on one side of your body or the inability to speak.
  • Detached retina. This is the detachment of the light-sensing layer inside the eyeball from the blood vessels transporting its oxygen and nutrients.
  • Transient Ischemic Attack. A transient ischemic attack leads to temporary stroke-like symptoms. This may indicate an impending stroke.
  • Optic neuritis. Optic neuritis is the inflammation of the optic nerve.
  • Eye injury. An eye injury must be assessed immediately by emergency medical help.
  • Glaucoma. Glaucoma damages the optic nerve of the eye. This is often caused by increased pressure in the eye.

Life-Threatening Symptoms of Blurry Vision

In some cases, blurred vision in one eye can be a sign of a medical emergency. Other severe symptoms that may coincide with blurry vision include:

  • A sudden change in vision
  • Loss of vision
  • Severe eye pain
  • A change in the level of alertness or consciousness
  • Sudden numbness or weakness on one side of the body

Seek immediate medical attention by calling 911 if you or anyone else experiences these blurry vision symptoms.

Risks & Complications of Blurry Vision In One Eye

In most cases, blurred vision in one eye isn’t caused by severe conditions or illnesses. However, in rare circumstances, blurry vision may link with a systemic disease or condition. If left untreated, this can lead to vision-threatening or life-threatening complications.

  • Vision loss and blindness
  • Brain damage
  • Spread of cancer
  • Spread of infection
  • Unconsciousness

If you have blurry vision in one eye, contact your eye doctor to assess your condition's underlying cause. You may have to take an eye exam to determine the problems of your vision problems. If necessary, your doctor will prescribe you treatment to help.

Blurry Vision FAQs

What can cause sudden blurry vision in one eye?

Sudden blurred vision in one eye can be the result of many ocular or medical conditions including a detached retina, stroke, eye strain, conjunctivitis (pink eye), corneal abrasion, high blood sugar levels, eye trauma, keratitis, migraine, and other conditions. If your blurred vision remains persistent, recurring, or causes you concern, contact a healthcare professional for medical advice.

Is blurred vision in one eye a sign of a stroke?

Blurred vision in one eye is one symptom of a stroke. It is usually accompanied by at least one other symptom including severe headache, slurred speech, loss of muscle control, and numbness or paralysis in your face, arm, or leg.

Is blurred vision a sign of heart problems?

Blurred vision may be a sign of stroke if accompanied by other stroke symptoms. Blurred vision is a symptom of several medical conditions.

Is sudden blurred vision an emergency?

Sudden blurred vision should be considered an emergency if it is accompanied by other symptoms such as: severe headache, difficulty speaking, loss of muscle control on one side of your body, facial drooping, or other vision changes.

When should I go to the ER for blurred vision?

If your blurred vision is caused by eye injury or trauma, you should go to the ER. You should also seek prompt medical attention if blurred vision is accompanied by a severe headache, difficulty speaking, loss of muscle control on one side of your body, numbness or paralysis in your face, arm or leg that develops suddenly, or facial drooping.

How do you get rid of blurry vision?

Blurry vision treatment depends on the cause. Eyeglasses or contact lenses can treat refractive errors, and eye drops can treat dry eyes. Medical conditions such as stroke need to be treated by a doctor. Some conditions may require eye surgery such as LASIK to get rid of blurry vision. Contact your optometrist or opthalmologist for more information.

If you experience vision changes as well as a tingling in your face, it is most definitely an emergency. As Schreiber says, these are two signs of a stroke, which is clearly a reason to seek immediate medical help.

Black spots in your vision, as well as blurriness, may be a sign of an eye condition known as macular degeneration. So these are two symptoms you don't want to keep to yourself. "A diagnosis of macular degeneration early on can help patients prevent the advancement of the disease," Dr. Jean Keamy, board-certified ophthalmologist, tells Bustle. "Treatment options for macular degeneration include vitamin therapy, lifestyle changes, and sometimes injections into the eye."

The Causes of Eye Pain

The easiest way to tell if a pain or feeling is a symptom of anxiety is to determine whether or not it appears to get worse during times of stress. Still, for some that can be tricky - those with generalized anxiety disorder, for example, are often feeling stress, and this can make it difficult to tell when their eye pain is or is not connected to their stress. For some it may feel like the eye pain is what's causing the increase in stress - and this is entirely possible as well.

There are several potential reasons for eye pain. They include:

  • Pupil Dilation Anxiety disorders are linked to the activation of your fight or flight system - an evolutionary reflex designed to keep you safe in times of danger. One of the things that happens during the fight or flight response is pupil dilation, which is believed to help your eyes draw in more light in case you need better vision to fight or flee. Unfortunately, this can also cause your eyes to experience more pain from the over-abundance of lighting, similar to looking at the sun.
  • Eye Strain For similar reasons, anxiety can make your eyes a bit more blurry and make it harder to focus. So when you do focus, this may be causing you to experience some eye strain. Eye strain can be quite painful, and in some cases is made worse if you already have slightly affected vision.
  • Migraines Stress also causes migraines, and migraines can cause both eye pain and vision problems. Furthermore, some people may experience "silent migraines" which can cause many of the same symptoms of migraines but without the associated headache.
  • Muscle Tension Anxiety may also lead to tension spreading throughout the muscles in your body, and in some cases this can lead to severe muscle tension around your eyes and face. That muscle tension can occasionally lead to very intense pain that may radiate around any single eye or both eyes, depending on where the tension occurs.

Some of the causes of eye pain from anxiety are not entirely clear, but there are so many things that happen to people's bodies during stress that the idea that anxiety might be linked to eye pain is not implausible.

Some people may also become over sensitive to their eye pain, because anxiety does have the effect of making people pay more attention to the way they feel, especially if it's something that causes them stress.

What are eye migraines?

They're commonly called eye migraines, but they're actually a group of different types of migraine. Often these migraines are called ocular migraines (or occular), ophthalmic migraines, silent migraine, acephalgic migraine, and even ophthalmoplegic 'migraines'. Confused? With good reason! Most of these terms are out dated, and sometimes defined in very different ways!

First, you need to remember that pain is only one possible symptom of migraine (see the article on symptoms). Other symptoms include nausea, congestion, and visual symptoms. Silent migraine or acephalgic migraine is migraine without the headache.

(Note: many of these migraine types are also diagnosed as complicated migraine. Read more about the complicated migraine diagnosis here)

Eye migraines – silent migraine:

If this is you, you may be getting strange visual disturbances, usually lasting less than an hour, but no headache. You likely have a type of migraine, which needs to be treated in basically the same way as any other type of migraine. However, you do need to make sure you see a good doctor so that she can rule out other problems that can do permanent damage. Normally today silent migraine is referred to as migraine aura without headache.

Eye migraines – Occular migraines:

The term ocular migraine (sometimes spelled occular migriane) is another one that is no longer generally used. Most often in the past it has referred to retinal migraine, a rare type of migraine that has severe visual disturbances or blindness in one eye during an attack. Sometimes the term has also been used to describe other types of migraine that have visual auras, such as the much more common migraine with aura.

If you are diagnosed with ocular migraine, it would be helpful to ask your doctor for a more specific diagnosis from the International Headache Society's classifications. The other important thing is to rule out other eye problems, which could be quite serious.

Once again, it's a good idea to see a doctor or ophthalmologist to make sure there isn't something else going on. It's especially important to see a doctor if your symptoms are accompanied by headache.

Eye migraines - Ophthalmic migraine:

Ophthalmic migraine ( also called opthalmic migraine) has the same symptoms as the occular migraines mentioned above, but occur at the height of the migraine, and most often occur in young men. Sometimes as time progresses the migraine sufferer will lose the headache and end up with a ophthalmic migraine which is a silent migraine (are you getting the hang of this now?). These are much more common eye migraines.

The International Headache Society doesn't use this classification. That's why you may read a variety of descriptions with the same name. But many of these are now outdated.

Eye migraines – ophthalmoplegic migraine:

These have been called a rare type of migraine, though researchers now believe it's not technically a migraine at all. The headache is usually severe, and is accompanied by weakness in one or more of the eye muscles. Because of the decreased eye movement, you may experience temporary (less than 2 hours) double vision, drooping eyelid, or dilated pupil. Most often this problem is diagnosed in children.

It is very important to have a thorough examination if you suspect you may have ophthalmoplegic migraine. Dr. Seymour Diamond writes in Conquering Your Migraine,"Double vision and muscle weakness may be caused by an aneurysm or it may have another organic origin. the individual should undergo a thorough examination and appropriate testing to rule out conditions other than ophthalmoplegic migraine."

Eye migraines - Basilar migraines

Basilar migraines are not strictly just “eye migraines”, but the eye symptoms are often quite obvious and severe. These symptoms include a visual aura but also eye twitching, a graying out visually or even temporary partial blindness, vertigo, dizziness and more. This type of migraine is rare, but has some concerns of its own, so we have another article with all the details. Read here about basilar migraines and the unique problems that come with them.

Warning signs of a serious eye problem

Eyes aren't exempt from the wear and tear of aging. Some of the age-related changes in the eyes are annoying but not serious — for example, it can become difficult to focus on near objects, and eyelashes may thin out a bit. But other changes can be serious eye problems that threaten vision.
With age, the eyes' ability to stay lubricated starts to wane. This can leave eyes feeling irritated, sticky, dry, or gritty. The lens of the eye can become less elastic. Night vision may also start to suffer, which can pose problems when driving at night. In contrast, cataracts, macular degeneration, and diabetic retinopathy can rob you of your sight.
How do you know if an eye problem is a nuisance or the start of something serious? The following signs and symptoms warrant a call to your doctor. Catching serious eye problems early can help preserve your vision. Even non-vision-threatening eye problems can be treated to keep your eyes comfortable and your eyesight as sharp as possible.

Call your doctor if you experience any of the following:

  • Change in iris color
  • Crossed eyes
  • Dark spot in the center of your field of vision
  • Difficulty focusing on near or distant objects
  • Double vision
  • Dry eyes with itching or burning
  • Episodes of cloudy vision
  • Excess discharge or tearing
  • Eye pain
  • Floaters or flashers
  • Growing bump on the eyelid
  • Halos (colored circles around lights) or glare
  • Hazy or blurred vision
  • Inability to close an eyelid
  • Loss of peripheral vision
  • Redness around the eye
  • Spots in your field of vision
  • Sudden loss of vision
  • Trouble adjusting to dark rooms
  • Unusual sensitivity to light or glare
  • Veil obstructing vision
  • Wavy or crooked appearance to straight lines
