Common Causes of Blurry Vision in One Eye

Blurry vision in one eye can be a concerning symptom, but it’s often not a sign of a serious condition. However, understanding the potential causes is crucial for proper diagnosis and treatment. Let’s explore some of the most common reasons for this issue:

Refractive Errors

The Centers for Disease Control and Prevention (CDC) report that refractive errors are the most prevalent cause of eye problems in the United States. These include:

• Myopia (nearsightedness)
• Hyperopia (farsightedness)
• Astigmatism (distorted vision at all distances)
• Presbyopia (difficulty seeing objects up close)

Refractive errors can cause blurry vision, hazy sight, double vision, halos around bright lights, eye strain, and headaches. Fortunately, these issues are typically correctable with eyeglasses, contact lenses, or in some cases, surgery.

Eye Infections

Various pathogens, including bacteria, fungi, and viruses, can cause eye infections affecting one or both eyes. Symptoms may include:

• Redness or bloodshot appearance
• Itching and swelling
• Pain and discomfort
• Discharge or crust around the eyes
• Vision problems, including blurriness

Conjunctivitis, commonly known as pinkeye, is a frequent type of eye infection. However, more severe infections like cellulitis require prompt medical attention. Treatment options range from eye drops and topical medications to oral antibiotics, depending on the underlying cause.

Migraine with Aura

Migraine is a neurological condition characterized by moderate to severe headaches, often accompanied by sensory disturbances called auras. These auras can cause:

• Blurry vision
• Temporary vision loss
• Visual phenomena like shapes or zig-zag lines
• Tingling sensations
• Weakness
• Speech difficulties

The American Migraine Foundation notes that aura symptoms typically last 20-60 minutes. Some individuals may experience silent migraines, which involve aura symptoms without the associated headache pain. Treatment usually involves pain relievers, ranging from over-the-counter options to prescription medications like triptans for frequent episodes.

Age-Related Eye Conditions Affecting Vision

As we age, our eyes become more susceptible to certain conditions that can cause blurry vision in one or both eyes. Two common age-related eye problems are cataracts and age-related macular degeneration (AMD).

Cataracts

Cataracts develop when the lens of the eye becomes cloudy, leading to blurry vision. This condition can affect one or both eyes and is particularly common in older adults. Symptoms of cataracts include:

• Blurry or hazy vision
• Reduced color perception
• Difficulty seeing at night
• Trouble with reading
• Double vision
• Halos around lights

The only effective treatment for cataracts is surgery, during which a surgeon replaces the clouded lens with an artificial one. This procedure is generally safe and can significantly improve vision quality.

Age-Related Macular Degeneration (AMD)

AMD affects the macula, the part of the eye responsible for sharp, central vision. It can begin in one eye and progress to the other, causing a loss of central vision. There are two types of AMD:

1. Wet AMD: Caused by abnormal blood vessel growth behind the retina, leading to bleeding and scarring. An early symptom is straight lines appearing wavy.
2. Dry AMD: More common, accounting for 70-90% of cases. It occurs as the macula thins with age, resulting in blurry vision. Tiny yellow or white deposits called drusen under the retina are an early sign.

While there’s no cure for AMD, various strategies can help slow its progression:

• Quitting smoking
• Maintaining a balanced diet
• Regular exercise
• Managing blood pressure and cholesterol levels

When to Seek Emergency Medical Attention

While many causes of blurry vision in one eye are not life-threatening, certain symptoms warrant immediate medical attention. Seek emergency care if you experience blurry vision along with:

• A sudden, severe headache
• Headache following a head injury
• Difficulty staying awake or loss of consciousness
• Facial drooping or numbness on one side
• Inability to raise one or both arms
• Slurred speech

For individuals with diabetes, the following symptoms require urgent medical evaluation:

• Sudden vision changes, such as flashes of light
• A significant increase in eye floaters
• Vision resembling a curtain being pulled over the eye

Diagnostic Approaches for Blurry Vision

When experiencing blurry vision in one eye, a comprehensive eye examination is crucial for accurate diagnosis. Eye care professionals may employ various diagnostic techniques to identify the underlying cause:

Visual Acuity Test

This standard eye chart test measures how well you can see at various distances. It helps detect refractive errors and other vision problems.

Refraction Assessment

Using a phoropter, the optometrist or ophthalmologist determines the exact lens prescription needed to correct your vision.

Slit-Lamp Examination

This microscope allows for a detailed view of the eye’s structures, helping to identify infections, cataracts, or other abnormalities.

Dilated Eye Exam

By dilating the pupils, the doctor can examine the retina and optic nerve for signs of disease or damage.

Optical Coherence Tomography (OCT)

This non-invasive imaging test provides detailed cross-sectional images of the retina, useful for diagnosing conditions like AMD.

Treatment Options for Blurry Vision

The treatment for blurry vision in one eye depends on its underlying cause. Here are some common approaches:

Corrective Lenses

For refractive errors, prescription eyeglasses or contact lenses can significantly improve vision clarity.

Medications

Eye drops or oral medications may be prescribed for infections, inflammations, or certain eye diseases.

Lifestyle Changes

In some cases, modifying diet, exercise habits, or quitting smoking can help manage eye health and improve vision.

Surgery

Procedures like LASIK for refractive errors or cataract surgery may be recommended in appropriate cases.

Vision Therapy

This form of physical therapy for the eyes and brain can be effective for certain vision problems, particularly in children.

Preventing Eye Health Issues

While not all causes of blurry vision are preventable, there are steps you can take to maintain good eye health:

• Regular eye exams: Annual check-ups can catch problems early.
• Protect your eyes: Wear sunglasses and protective eyewear when necessary.
• Healthy lifestyle: A balanced diet, regular exercise, and avoiding smoking benefit eye health.
• Digital eye strain prevention: Follow the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds) when using digital devices.
• Proper lighting: Ensure adequate lighting when reading or working to reduce eye strain.

Living with Chronic Eye Conditions

For individuals diagnosed with chronic eye conditions that cause blurry vision, adapting to life with vision changes can be challenging. Here are some strategies to cope:

Assistive Technologies

Various devices and software can help those with vision impairments, including:

• Magnifying glasses and electronic magnifiers
• Text-to-speech software
• Large-print books and devices
• Specialized lighting solutions

Support Groups

Connecting with others who have similar experiences can provide emotional support and practical tips for managing vision problems.

Occupational Therapy

An occupational therapist can teach strategies to perform daily tasks more easily with impaired vision.

Regular Monitoring

Consistent follow-ups with eye care professionals are crucial for managing chronic conditions and preventing further vision loss.

Understanding the causes of blurry vision in one eye and knowing when to seek medical attention are crucial for maintaining eye health. While many causes are benign and easily treatable, some may indicate more serious underlying conditions. Regular eye check-ups, a healthy lifestyle, and prompt attention to vision changes can help ensure optimal eye health and clear vision for years to come.

Remember, your eyes are invaluable assets, and taking proactive steps to care for them is an investment in your overall well-being and quality of life. If you experience persistent or concerning vision changes, don’t hesitate to consult with an eye care professional for proper evaluation and treatment.

Causes, treatments, and what to do

Common causes of blurry vision in one eye include refractive errors, infections, migraine, and cataracts.

Most causes of blurry vision are not serious. However, it is important to consult a doctor about sudden or persistent blurry vision, as it could be a symptom of a condition that requires treatment.

This article will look at some of the causes of blurry vision in one eye, along with the symptoms and treatments.

In many cases, blurry vision is not a sign of a life threatening condition. However, sudden vision changes can sometimes mean a person needs emergency treatment. Being aware of the signs of these conditions can help with deciding when to seek help.

Anyone who experiences blurry vision along with any of the following symptoms should seek emergency medical attention:

• a sudden, severe headache
• a headache following a knock to the head
• difficulty staying awake
• loss of consciousness
• drooping or numbness on one side of the face
• inability to raise one or both arms
• slurred speech

People with diabetes should also seek help right away if they experience:

• sudden vision changes, such as flashes of light
• many more eye floaters than usual
• vision that resembles a curtain being pulled over the eyes

Read on to find out about some of the more common causes of blurry vision in one eye.

The Centers for Disease Control and Prevention (CDC) state that refractive errors are the most common cause of eye problems in the United States.

Refractive errors include:

• nearsightedness, or myopia
• farsightedness, or hyperopia
• astigmatism, or distorted vision at all distances
• presbyopia, or difficulty seeing objects up close

The most common symptom of a refractive error is blurry vision, but it can also cause:

• hazy vision
• double vision
• seeing halos around bright lights
• eye strain
• headaches

Eyeglasses or contact lenses can help people with refractive errors see more clearly. However, some people may need surgery.

Bacteria, fungi, and viruses can all cause an eye infection, and they can affect one or both eyes. Potential symptoms of an eye infection include:

• red or bloodshot eyes
• itchiness
• swelling
• pain
• discharge or crust around the eyes
• vision problems, including blurry vision

Conjunctivitis, or pinkeye, is a common type of eye infection. Other types, such as cellulitis, can be severe if a person does not receive treatment.

If a person has the symptoms of an eye infection, they should seek medical care. Depending on the cause, treatment could involve eye drops, topical medications, or oral antibiotics.

Learn about types of eye infection and their treatments here.

Migraine is a condition that causes moderate to severe headaches. Some people also experience auras, which are sensory disturbances that occur before or during a headache.

Aura symptoms can include:

• blurry vision
• short-term vision loss
• seeing shapes or zig-zag lines
• tingling
• weakness
• difficulty speaking

According to the American Migraine Foundation, these symptoms will usually last 20–60 minutes for those who experience aura. People can also have silent migraine, which is a migraine with aura but no pain.

Treatment for migraine usually involves pain relievers. Over-the-counter medications may be sufficient for those with an occasional migraine. However, those with frequent episodes may require prescription options, such as triptans, to manage the condition.

Cataracts develop when the lens of the eye clouds over, causing blurry vision. This can happen in one or both eyes. Cataracts tend to be age-related and are common in older adults.

The symptoms of cataracts can come on over time. They include:

• blurry vision
• hazy vision
• less colorful vision
• difficulty seeing at night
• difficulty reading
• seeing double
• seeing a halo around lights

The only way to treat cataracts is through surgery. During the operation, a surgeon will replace the clouded lens with an artificial one.

Learn about cataract surgery and recovery here.

Age-related macular degeneration (AMD) affects the macula, which is the part of the eye that enables people to see fine details. The condition can start in one eye and progress to the other, causing a loss of sharp or central vision.

There are two types of AMD:

Wet AMD

Wet AMD occurs when blood vessels form behind the retina and under the macula. These bleed and leak into the eye, scarring and damaging it.

Straight lines appearing wavy is an early symptom of wet AMD.

Dry AMD

As people get older, the macula gets thinner, leading to blurry vision. This is the most common form of AMD, accounting for 70–90% of cases. Drusen, or tiny yellow or white deposits under the retina, are the most common early sign of dry AMD.

There is no cure for either type of AMD. However, there are things people can do to slow its progression, including:

• stopping smoking
• eating a balanced diet
• exercising regularly
• maintaining healthy blood pressure and cholesterol levels

In people with wet AMD, doctors may also recommend anti-vascular endothelial growth factor drugs or laser treatment.

For people living with diabetes, blurry vision may be a sign of diabetic eye disease. This occurs when high blood glucose levels damage the blood vessels in the eye, causing conditions such as:

• diabetic retinopathy
• diabetic macular edema
• cataracts
• glaucoma

There are often no early symptoms of diabetic eye disease, but a person may experience:

• blurry vision
• vision that changes from day to day
• areas of darkness or vision loss
• a loss of color vision
• dark strings or floaters
• flashes of light

It is important for people with diabetes to get annual dilated eye exams, as these can help doctors detect early signs of damage.

People can lower the risk of these complications by managing their blood glucose levels, blood pressure, and cholesterol levels.

Treatment for existing diabetic eye disease may involve medications, laser procedures, surgery, or a combination of all three.

Sometimes, blurry vision is a sign of stroke. A stroke happens when something stops blood from getting to part of the brain. This might be a blood vessel blockage or rupture.

People can remember the symptoms of a stroke by acting F.A.S.T. This acronym stands for:

• face drooping
• arm weakness
• speech difficulty
• time to call 911

Sudden trouble seeing or walking or a severe headache can also be symptoms of stroke. Treatment may include medications to break up blood clots, procedures to repair blood vessels, or surgery.

If a person has these symptoms, do not hesitate to call for an ambulance. Paramedics can begin treatment on the way to the hospital.

Some people with COVID-19 experience conjunctivitis, which can cause blurry vision, red or watery eyes, and a sensation that a foreign object is in the eye. As with other types of viral conjunctivitis, these symptoms will usually go away on their own.

However, it is important to stay indoors and seek testing if COVID-19 is a possibility. Even with few or mild symptoms, it is possible to transmit the virus that causes COVID-19 to others.

Other symptoms of COVID-19 include:

• fever or chills
• cough
• shortness of breath or difficulty breathing
• fatigue
• muscle or body aches
• headache
• loss of taste or smell
• sore throat
• stuffy or runny nose
• feeling or being sick
• diarrhea

Anyone who suspects they have COVID-19 can find out how to get tested by contacting their local health authority or visiting its website.

A number of things can cause blurry vision in one eye. Refractive errors are a common cause, as are age-related conditions, such as cataracts and AMD. Some people with migraine may experience blurry vision if they get aura or silent migraine.

A doctor can diagnose the cause of blurry vision and recommend the best options for treatment. However, if a person may have conjunctivitis as a result of COVID-19, it is important to call ahead before visiting a healthcare professional in person.

People with sudden vision changes or loss should seek immediate medical help, particularly if they also have underlying conditions, such as diabetes.

11 Causes of Blurry Vision in One Eye

Dr. Russel Lazarus, March 8, 2022

Are you experiencing blurry vision in just one eye? This could be a sign of a serious eye condition.

While blurry vision is often associated with a need for eyeglasses or a new optical prescription, monocular blurry vision can signal a more serious condition that requires immediate attention.

Blurry vision that comes on suddenly or appears only in one eye can be a sign of a medical emergency and should be evaluated immediately by an eye doctor or another medical professional.

Here are six emergencies that can cause blurry vision in one eye:

1. Stroke

Blurry vision in one or both eyes can occur when a stroke affects the visual areas of the brain. Seek immediate medical attention if you are experiencing any of the following symptoms along with blurry vision:

• Severe headache
• Disorientation
• Difficulty speaking or understanding speech
• Imbalance or walking issues
• Numbness or tingling in extremities, especially on one side

2. Retinal detachment

Retinal detachment is an eye emergency that occurs when the retina is pulled away from its normal position on the back wall of the eye.

This sight-threatening condition generally results in a sudden onset of blurred vision, along with:

• Flashes of light or eye floaters that move across your vision
• Decreased peripheral vision
• Appearance of a shadow or curtain in your visual field

3. Brain tumor

Brain tumors can put pressure on the visual processing areas of the brain and cause blurry vision, as well as other visual changes.

Other signs of a brain tumor include:

• Persistent headaches
• Confusion or difficulty concentrating
• Memory loss
• Trouble speaking
• Weakness of one side of the body
• Balance and coordination issues

4. Closed-angle glaucoma

Closed-angle glaucoma is an eye emergency that occurs when ocular fluid cannot drain properly, resulting in a sudden buildup of intraocular pressure. The elevated pressure presses on the optic nerve, causing permanent damage and vision loss, usually in one eye.

Other signs of closed-angle glaucoma include:

• Headache
• Severe eye pain
• Nausea and vomiting
• Seeing halos around lights

5. Wet macular degeneration

Macular degeneration (AMD) is a sight-threatening eye condition that affects the macula, the center of the retina, responsible for central vision and vision for fine details.

There are two forms of macular degeneration: dry and wet.

In the wet form, one eye may suddenly experience a bleed or leakage of fluid, resulting in an immediate loss of vision in that eye – this is an eye emergency.

One of the first signs of AMD is blurry vision in one or both eyes.

Other signs of AMD include:

• Appearance of dark or blind spots in your central vision
• Wavy vision or other visual distortions in your central vision
• Difficulty reading and driving
• Trouble with facial recognition
• Inability to see fine details

6. Diabetic retinopathy

Diabetic retinopathy is a serious eye condition that affects people with diabetes. It develops when elevated blood sugar levels remain high for long periods of time, damaging the tiny blood vessels throughout the body, including in the retina.

When the retinal blood vessels become damaged, they begin to leak fluid, resulting in retinal swelling and blurred vision.

Other signs of diabetic retinopathy include:

• Double vision
• Seeing floaters in your field of vision
• Increasing dark spots in your field of vision
• Poor night vision

5 less-urgent causes of blurry vision in one eye:

While the following causes don’t usually require an emergency trip to the eye doctor, treatment is still necessary to prevent any complications.

1. Conjunctivitis (pink eye)

Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva, the thin membrane that covers the white part of the eye and lines the inner eyelids. It can occur in one or both eyes, and while mild cases don’t usually impact vision, more serious cases can result in blurry vision.

Other symptoms of pink eye include:

• Whites of the eye appear red or pink
• Itching or burning in the eye
• Swollen eyelids
• Gritty sensation in the eye
• Excessive tearing
• Discharge from the eye

2. Other eye infections

Many different eye infections can result when bacteria, viruses or fungi enter the eye. Any of these infections can lead to blurry vision.

Common eye infections that result in blurry vision include:

• Covid-19
• Endophthalmitis
• Keratitis
• Optic neuritis
• Ocular herpes
• Uveitis

3. Retinal migraine     

A retinal migraine causes blurry vision and temporary blindness in one eye that usually lasts less than one hour. It can precede a headache or appear during, or after a headache.

4. Cataract

A cataract is the clouding of the eye’s naturally transparent lens, resulting in blurry vision in that eye. Although cataracts generally develop in both eyes, the clouding of the lens can occur at different rates, causing a difference in severity of blurred vision between the two eyes.

Other signs of a cataract include:

• Sensitivity to glare from sunlight, bulbs, headlights
• Seeing halos around lights
• Poor night vision
• Colors appearing less vibrant
• Double vision

5. Eye strain

Eye strain is often a symptom of excessive screen time or a prolonged near vision activity. Eye strain often leads to other uncomfortable symptoms, including:

• Blurry vision
• Headache
• Eye fatigue
• Dry eyes
• Neck and shoulder pain

Prevention of tunnel vision

Is it possible to improve peripheral vision by 100%?

Is it possible to cure carpal tunnel on my own?

Peripheral vision is made possible by the work of retinal photoreceptor cells, cones and rods. The space in the zone of our visibility is called the field of view, and the areas outside this zone are peripheral areas, into which objects fall, on which the main attention is not concentrated. For example, when we look straight ahead, and with peripheral vision we notice some kind of movement or person.

Central vision, on the contrary, is responsible for the visibility zone directly in front of us, the ability to clearly see both near and distant objects if a person does not have refractive anomalies – myopia, hyperopia, astigmatism.

Peripheral (lateral) vision disorders

One of the common pathologies among peripheral vision disorders is tunnel vision. This anomaly occurs as a result of pathological changes in the lateral parts of the retina.

Tunnel vision syndrome is a condition in which a person is unable to see with peripheral vision. The view is possible only with the central vision, and the visible field turns into a kind of tunnel, where the view is closed on the periphery.

Tunnel vision syndrome can occur for several reasons. Among them, an overdose of illegal psychotropic substances is called, which can affect visual function as well. Also, the prerequisites include prolonged oxygen starvation, poisoning with nitrogen fumes, chronic stress, sudden pressure drops.

Other pathologies of peripheral vision can also be associated with damage to the retina as a result of trauma, foreign objects entering the eye, and impacts. All this can provoke retinal detachment, in which a person begins to lose vision from the periphery.

Brain diseases can also affect peripheral vision due to injuries, concussions, and oncological pathologies.

Causes of tunnel vision

• Progressive open-angle glaucoma.
• Eye injuries.
• Pathological changes in the retina, which are usually caused by heredity.
• Cataract development.
• Damage to the optic nerve.
• Inflammation, infectious and inflammatory eye diseases.

Symptoms of tunnel vision

The syndrome manifests itself quite clearly, and the person immediately understands that there are obvious vision problems. Lateral visual zones can narrow either gradually or in some cases abruptly, for example, with retinal detachment.

First, it will be more difficult for a person to distinguish objects from the side: they will become blurry and fuzzy, or they will simply be practically impossible to distinguish. Secondly, visual acuity will noticeably decrease at dusk and at night. Thirdly, so-called “scotomas” may appear in the field of view – dark circles, which are the clearest signs of a serious lesion of the optic nerve.

One of the eloquent indicators of peripheral vision impairment is that it becomes almost impossible for a person to read a book. Trying to read printed text causes discomfort. Drivers, in order to see the obstacle on the right, need to turn their heads to notice another motorist. Therefore, tunnel vision syndrome is especially dangerous for drivers, people working in production.

Peripheral vision lost. What to do? Diagnosis of peripheral vision disorders

At the first signs of peripheral vision problems, it is important to see an ophthalmologist as soon as possible. To prevent loss of lateral vision, it is necessary to check with an optometrist at least once a year in order to detect the development of eye pathologies at an early stage.

Diagnosis of peripheral visual impairment includes physical examination of the patient using a slit lamp. In addition to the standard examination, a comprehensive vision diagnostics is required, which will reveal objective indicators of the state of the visual system.

The list of diagnostic measures, as a rule, includes perimetry, a study that determines the presence of loss of areas of the peripheral visibility zone, tonometry, measurement of ophthalmotonus to exclude the presence of glaucoma, ophthalmoscopy, assessment of the fundus. The ophthalmologist also checks visual acuity using special tables and a modern device – an autorefractometer.

The ophthalmologist examines the diagnostic data and anamnesis, after which he prescribes an effective treatment for the patient. In no case should you self-medicate and delay a visit to an ophthalmologist. This can lead to a worsening of the situation, the progression of possible eye diseases.

Treatment of peripheral vision disorders

The treatment of tunnel vision syndrome in most cases is lengthy and time-consuming. During this period, it is important to ensure the safety of the patient at home and at work: remove dangerous objects that a person may not notice with peripheral vision. For example, knives, sharp corners, any other piercing and cutting objects.

If the patient drives a car, it is best to limit or completely avoid driving during treatment. Otherwise, there is a risk of accidents. As a pedestrian, you also need to be careful. It is better that a close person helps the patient to cross the road, who will make sure that it is safe to cross the street and that a car does not rush from the side.

Peripheral vision disorders can be treated with medication and physiotherapy. In extreme cases, surgery may be required.

As a means of drug therapy, the doctor may prescribe drugs aimed at eliminating puffiness, improving blood circulation in the organ of vision, normalizing intraocular pressure, the work of the optic nerve, and improving metabolic processes in the tissues of the eye. Drip therapy can help improve peripheral vision.

When surgery is required for peripheral vision loss

Surgery for tunnel vision is indicated if the patient has an indication. As a surgical method, laser vision correction can be prescribed, which is carried out on modern laser equipment for fifteen minutes in both eyes. Laser correction is highly effective, gives a predictable result and is characterized by a short rehabilitation period without significant changes in the patient’s lifestyle.

Physiotherapeutic methods are also used to restore the visual functions of peripheral vision. These include electro and magnetostimulating technologies for influencing the optic nerve. Scientists are developing special glasses that improve peripheral vision.

Prevention of tunnel vision

The most important prevention of pathologies of the organ of vision, reducing its sharpness is regular observation by an ophthalmologist. This is especially true for people with myopia, hyperopia, astigmatism, as well as patients older than 40-45 years. It is at this age that the risks of developing cataracts, glaucoma, and retinal diseases increase several times due to age-related changes in the body.

For prevention, it is important to exclude bad habits from life: smoking, alcohol. You need to lead an active lifestyle, play sports, include in the diet a variety of foods rich in vitamins, trace elements that are useful for the normal functioning of the visual system.

Is it possible to improve peripheral vision by 100%?

The ability to fully restore peripheral vision depends on the cause that caused the pathological processes. In most clinical situations, with timely treatment, lateral visibility zones are restored.

Can carpal tunnel be cured on my own?

You cannot get rid of tunnel vision syndrome on your own. Attempts to self-medicate will only aggravate the situation and lead to even greater vision problems. At the first symptoms, you need to contact an ophthalmologist in a specialized eye clinic.

Blurred vision in one or both eyes – [Dr. Kurenkov Clinic]

Blurred vision is when the vision loses its sharpness and instead of a clear picture, you see a blurry image. Objects seem to be out of focus and have blurred outlines.

It is quite logical that such a problem causes concern. There are many reasons for blurry vision. It can be myopia, farsightedness, astigmatism, presbyopia, all these vision problems are related to refractive errors. Sometimes the loss of image clarity can be evidence of dangerous diseases and neurological disorders that should not be ignored.

If you have problems with vision, then the first thing we do is go to the doctor, he will check your eyes in all respects and determine if treatment is needed. It is very important to check the eyes comprehensively.

Causes of blurred vision and how to cure it

Nearsightedness or myopia : In this case, you feel excessive tension in your eyes, up to a headache. There may be strabismus and blurred vision in one eye or both.

Treatment options include wearing glasses, contact lenses, surgical methods such as LASIK operations or photorefractive keratectomy.

Hyperopia : in this case, you can see objects in the distance perfectly, but not near. To see an object up close, you have to strain your eyesight. The eyes are very tired in this case. The treatments are similar to myopia – glasses, contact lenses or refractive eye surgery.

Astigmatism: If you have trouble seeing objects both near and far, this may be a sign of astigmatism. Its cause is the deformed shape of the cornea.

In this case, the light rays do not focus on the retina, which means that a clear picture does not add up, the distance to the object in this case does not matter.

Methods of treatment – glasses, lenses, surgery.

Presbyopia : This disease is a consequence of the body’s natural aging. And if your age is over forty, don’t be surprised that you find it hard to read text messages on your phone, the fine print on the package. As a treatment, your doctor may prescribe glasses to correct refractive errors and presbyopia. Additional options in glasses such as anti-reflective coating and photochromic lenses are very important. For more information about which glasses are best for you, contact your optometrist.

Chronic Dry Eye Syndrome : If your eyes are often dry, this can cause the picture to become blurry from time to time. As a treatment for this ailment, the doctor will recommend you artificial tears – these are drops that have a lubricating effect. If the situation is very serious, then the doctor will prescribe prescription drugs or special plugs inserted into the lacrimal canal – they have several names – obturators, occluders of the lacrimal openings.

Pregnancy: when a woman is expecting a baby, her body often produces surprising reactions, including vision problems – a fuzzy picture or double vision. Hormones are to blame for everything – they are able to influence the shape and thickness of the cornea. All this leads to blurred vision. Often blurred vision is a consequence of dry eyes, which also often happens during pregnancy.

Eye migraines or migraine headaches :

Migraine is an extremely unpleasant condition, but not dangerous in general. Among the symptoms, one can distinguish the appearance of a veil before the eyes, the flickering of light and luminous zigzags.

Floating flies : You may experience vision problems when some strange flies are swimming in front of your eyes. Very often, this problem appears with age: the gel-like vitreous body of the eye loses its dense structure over the years and becomes more liquid. Tiny bits of tissue inside it float freely around the eye and cast shadows on the retina, which is why we see floating objects.

Blurry vision after LASIK surgery : Vision may be blurry after refractive surgery. But this unpleasant effect passes after a few days. However, it will take a little longer for vision to return to normal.

Eye drops and medicines : eye drops, or rather the preservatives that are part of them, can cause a fuzzy picture, as well as eye irritation. Dry eyes and blurred vision may be due to the use of histamine preparations. These side effects are usually indicated in the instructions for medications. If you don’t know why you have blurry vision, you can ask your doctor this question, and he will find out if this is a “side effect” from any medications.

Unsupervised wearing of contact lenses : Normally you can wear lenses for a short period of time, this period is indicated on the lenses themselves, but very often we neglect these recommendations. If you wear contact lenses for too long, dirt, including protein, accumulates in them. This can not only cause blurred vision, but also an eye infection.

Blurred vision as a symptom of dangerous vision problems

Eye diseases: if you are over 60 years old and you feel that your vision is blurred sharply, there is a risk that you have a macular hole – a retinal tear. Many eye diseases can result in irreversible loss of vision, so you should immediately go to the hospital if you feel that your vision has deteriorated sharply.

Cataract : This disease is dangerous because, if left untreated, you can become completely blind. Cataract symptoms are blurred vision, glare and halos around the world at night, the solution is cataract surgery and an artificial lens. These surgeries will restore lost vision.

Glaucoma: symptoms – fuzzy picture and “tunnel vision”. It is very important to start treatment on time, because otherwise you can completely lose the ability to see.

Age-related macular degeneration : In the course of this ailment, you suffer not so much from the fuzziness of the picture, but from the fact that the image becomes deformed – straight lines ripple or become broken. This age-related disease is again dangerous because you can completely go blind.

Diabetic Retinopathy : Diabetes can lead to diabetic retinopathy, a dangerous disease that causes serious damage to the retina.

Cardiovascular and other systemic diseases: blurred vision can be a sign of the onset of a very dangerous disease such as a stroke or cerebral hemorrhage.
