Blurry Vision From Dry Eyes

What Causes Blurred Vision

Treating Blurry Vision & Dry Eyes from Staring at Screens – SLUCare Health Watch

Blurred vision can be caused by eye conditions, including:

  • difficulty focusing your eyesight, such as with near-sightedness or far-sightedness
  • problems with the retina, such as diabetic retinopathy
  • an injury to the eye

Blurred vision can also be a symptom of another medical condition, such as:

Sometimes, blurred vision can be a side effect of medicines that you may be taking.

Why Can Dry Eye Syndrome Cause Blurred Vision

Most cases of dry eye syndrome result from problems with the tear glands, but certain medications, medical conditions and dry air can also be to blame. Even when there are enough tears in the tear film that coats the eye, they may evaporate too quickly.

The tear film is composed of a specific ratio of oil, mucus and water that work together to lock moisture in and keep debris and microbes out. Any imbalance of these 3 components can cause a number of dry eye symptoms, including:

  • Red, painful eyes
  • Burning or itchy eyes
  • Mucus discharge around eyelashes

Problems with the tear film can hinder the eyes ability to refract light properly. Thats why blurred vision is a common complaint in patients who suffer from dry eyes.

Dry Eye Treatment And Prevention

Dry eye syndrome is a chronic and typically progressive condition. Depending on its cause and severity, it may not be completely curable.

But in most cases, dry eyes can be managed successfully. Treatment usually results in greater comfort, fewer dry eye symptoms and, sometimes, sharper vision.

Dry eye disease can have a number of causes, and a variety of treatments are used.

Some optometrists and ophthalmologists may have you complete a questionnaire about your symptoms prior to initiating dry eye treatment. Your answers to this survey are then used as a baseline, and the questionnaire may be administered again after several weeks of treatment to evaluate the effectiveness of the treatment.

Successful treatment of dry eyes requires that you are willing to follow your eye doctor’s recommendations and that you use the products he or she recommends consistently.

The following is a list of dry eye treatments that are commonly used by eye doctors to reduce the signs and symptoms of dry eyes. Your eye doctor may recommend only one of these dry eye treatments or a combination of treatments, depending on the cause and severity of your condition.

What Causes Blurred Vision in One Eye &  How is it Treated

Mild to moderate cases of dry eye will not likely cause permanent damage or infection that will lead to blindness, especially when a person receives treatment.

More severe cases of dry eye can cause damage to the outer, clear layer of the eye known as the cornea. When damage occurs there, it can lead to impaired vision.

Corneal damage can cause blurry or cloudy vision, and it can also lead to blindness. Corneal damage is a leading cause of blindness globally, most commonly in low or middle income countries.

Causes Of Dry Eyes And Blurry Vision

Dry eye disease is traditionally classified into aqueous deficient and evaporative, depending on the development mechanism. So the causes of dry eyes and blurry vision differ with the type of disease.

For instance, Sjogren Syndrome is the primary cause of aqueous deficient dry eye . At the same time, Meibomian gland dysfunction is the most common cause of evaporative dry eye disease.

The two types of dry eyes are not mutually exclusive. Therefore, the cause of your dry eyes and blurry vision is most likely multifactorial, including local ocular disorders, systemic conditions and treatment-related events.

Here are the potential causes of dry eyes:

  • Medications such as antihistamines, corticosteroids, glaucoma drops and anticholinergic drugs
  • Rosacea, eczema and other skin diseases around the eye
  • Autoimmune diseases like Sjogrens syndrome, lupus and rheumatoid arthritis
  • Meibomian gland dysfunction
  • Thermal and chemical burns causing conjunctival scarring
  • Graft-versus-host disease in individuals with transplants
  • Long-term contact lens wear or a viral infection causing decreased corneal sensation
  • Environmental factors like low humidity and exposure to cigarette smoke

When doctors treat dry eye disease, they tackle the presenting symptoms, one of which is almost always blurry vision.

Dry Eyes & Blurry Vision: The Connection

Dry eyes and blurry vision are two common eye symptoms that are closely related. When eyes become too dry, due to poor tear production, they can cause blurry vision.

Blurred vision is one of the primary symptoms of dry eyes. Blurred vision, however, does not cause dry eyes.

For someone who experiences dry eyes and blurred vision, treatment should start by focusing on the dry eyes. As the cause of dry eyes is identified and treated, blurred vision will go away, and you should be able to see clearly once again.

Is Dry Eye Serious

Dry eyes are almost always a serious problem because burning, itchy, sensitive eyes affect every aspect of your daily life. But dry eyes can become a truly serious condition that ultimately causes vision loss, which is why you should call us at Smart Eye Care for prompt treatment, even if your symptoms seem mild.

Dangers If Dry Eyes Are Left Untreated

Public awareness of dry eye has increased over the past five years. This also will drive up diagnoses going forward.

Caroline Blackie, O.D., Ph.D.

Potential complications of untreated, dry eyes include:

  • Eye infections. Tears wash away debris and protect your eyes against infections by lysozyme activity. Therefore, having a dry eye increases the risk of developing eye infections such as keratitis.
  • Vision loss. Untreated, dry eyes can lead to blindness as the condition causes inflammation followed by corneal abrasion, which can progress to ulceration.
  • Poor quality of life. Chronic dry eye makes it challenging to perform daily activities like driving or reading.

What Is Dry Eye Disease

Dry eye disease is a common condition where you dont have enough quality tears to lubricate your eyes surface. This condition is often chronic and more prevalent in older adults. Your tears are vital for keeping your eyes clean and free of debris, but complications can arise within the layers of your tear film.

Instability in your tear film can lead to inflammation and damage your eyes. There are several reasons you can develop dry eye disease.

The Connection Between Dry Eyes And Blurry Vision

Untreated dry eye condition can lead to eye inflammation, corneal surface abrasion, consequent ulcers, and potentially vision loss.

Tears lubricate the eye, wash away debris on the cornea and keep the front surface of the eye clear. Thus, the lacrimal gland fluid reduces the risk of infection and enhances vision. With low volume or poor-quality tears, the possibility of developing an eye infection and vision changes also rises.

Leaving a dry eye condition untreated only invites more trouble. It can lead to eye inflammation, corneal surface abrasion, consequent ulcers and potentially vision loss.

Typically, dry eyes and blurry vision co-occur as symptoms. But in some instances, the two can signify other health conditions, particularly Sjogrens syndrome and lupus.

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:

Serious Causes Of Blurred Vision In One Eye


Blurry vision can occur when a stroke affects the brain regions associated with vision. A stroke happens when something reduces or blocks the blood flow to part of your brain.

Remembering the acronym FAST can help you identify the symptoms of a stroke. FAST stands for:

  • Weakness on one side of the body

Retinal Detachment

A detached retina can lead to blurry vision in one eye. The retina is the light-sensitive tissue at the back of your eye.

Increased light flashes and floaters can be early symptoms of retinal detachment. However, this condition can happen suddenly and without other symptoms.

Wet Macular Degeneration

There are two types of age-related macular degeneration : wet and dry. Both conditions can cause blurred vision that starts in one eye and progresses to the other. Both types cause blurriness and vision loss in the middle of your visual field .

Unlike the dry type, wet AMD starts suddenly and worsens rapidly. Although dry AMD progresses gradually, it can turn into the wet type and cause sudden symptoms.

Closed-Angle Glaucoma

Closed-angle glaucoma occurs when the fluid in your eyes cant drain properly. This causes a buildup of intraocular pressure. The increased pressure can damage the optic nerve and cause vision loss.

Closed-angle glaucoma usually affects one eye. Other symptoms include:

  • The appearance of halos around lights


  • Pus draining from the eyes

Diabetic Retinopathy

  • An increase in floaters and dark spots
  • Poor night vision

When the vitreous gel inside your eye rubs or pulls on the retina, you may see what looks like flashing lights or lightening streaks. You may have experienced this sensation if you have ever been hit in the eye and see “stars.” These flashes of light can appear off and on for several weeks or months.

This changes your point of focus or eliminates a point of focus completely, resulting in blurry vision. While considered harmless and normal, you should avoid intentionally blurring your vision if it hurts your head or eyes, or results in a lasting blurred sensation.

How is blurred vision prevented?

  • Always wear sunglasses that provide broad-spectrum protection when you’re going out in the sun.
  • Eat a diet rich in eye-healthy nutrients. …
  • Undergo regular comprehensive eye exams, especially if someone in your family has a history of an eye disease.
  • Watching TV too much or too closely will damage your eyes Watching too much TV or sitting very close to it may make your eyes tired or give you a headache  particularly if you are watching TV in the dark  but won’t cause any serious permanent damage.
