Dry Eyes And Blurry Vision

Can Dry Eye Cause Permanent Damage

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

Dry eye can cause permanent damage if the cornea gets scratched. Minor scratches will likely heal, but if scars form, they can cause long lasting vision problems.

When damage occurs to the cornea, a doctor may recommend various treatments. The options may include:

  • autologous serum tears

If these treatments prove ineffective, the doctor might recommend a corneal transplant to help restore clear vision. During this procedure, a surgeon removes all or part of the damaged cornea and replaces it with donor tissue. Most corneal transplants are successful initially, but some may fail due to the immune system attacking the implant.

Home Remedies For Dry Eye Syndrome

Artificial Tear Solutions

These ophthalmic preparations lubricate the eye, enhance contrast sensitivity, and reduce discomfort of the ocular surface. If you have Meibomian gland dysfunction, triglyceride-containing artificial tears are more helpful.

As a general principle, avoid using home therapies such as artificial tears that contain preservatives.

Warm compresses and eyelid massages can also alleviate the symptoms of dry eye. Nevertheless, the ultimate dry eye treatment requires identification and treatment of the cause.

Possible Cause: Eye Surgery

Dry eyes can be a side effect of cataract surgery and LASIK or PRK surgery, which correct vision problems. The nerves that help you make tears can be damaged during these procedures. Talk with your doctor about eyedrops and other things that can help. For most people, it gets better as your eyes recover.

Eye Disorders Focusing Problems

Problems with focusing are the most common eye disorders. These occur when the image of what you are looking at does not focus precisely on the back of the eye and appears blurry. The main types of refractive errors are myopia , hyperopia or hypermetropia , astigmatism and presbyopia .Refractive errors occur when there is a mismatch between the length of the eye and its optical power. These mismatches usually originate during childhood and are thought to be affected by both hereditary and environmental influences.

Trouble Wearing Contact Lenses

Dry Eyes and Blurred Vision from Gadolinium Deposition Disease

A 2017 study published in Contact Lens and Anterior Eye found that nearly half of contact lens wearers report dryness when wearing contacts too long. Long-term use of contact lenses can lead to dryness because your eyes cant produce as many tears.

This doesnt necessarily mean you have dry eye syndrome. However, if your contact lenses suddenly become uncomfortable to wear and you experience additional dry eye symptoms, you may want to get tested.

Health Conditions That Can Cause Severe Dry Eye

  • Diabetes: Nearly half of people with diabetes have dry eyes. The development of dry eye is often linked to a loss of nerves in the cornea . Without functional nerves in the cornea, tear production from the tear-producing lacrimal glands is decreased.
  • Rosacea: While rosacea is primarily known as a skin condition that causes facial redness and visible blood vessels, more than half of these patients also develop eye problems known as ocular rosacea. Approximately 80% of patients with ocular rosacea have meibomian gland dysfunction, which causes the eyelids to secrete fewer oils that blend with a patients natural tears. Without the oils, the patients tears evaporate too quickly, resulting in dry eyes.
  • Sjögrens syndrome: The immune system targets the glands that make tears and saliva, leading to dry eyes and dry mouth. Sjögrens syndrome can stand alone, though it often accompanies rheumatoid arthritis and lupus.
  • Rheumatoid arthritis: Dry eye disease in patients with rheumatoid arthritis can progress from annoying to painful quickly. Rheumatoid arthritis can also cause other eye conditions, which like dry eye disease, if not treated can lead to vision disturbances or loss.
  • Scleroderma: Because scleroderma causes a hardening or tightening of the bodys connective tissues, including the eyelids, the eyes are at risk. The condition can also decrease functionality in the tear producing glands of the eyes, reducing overall eye moisture.
  • The Link Between Dry Eyes And Blurry Vision

    Its clear that dry eyes can often lead to blurry vision. Why, though?

    Several of the causes of dry eye can easily lead to blurry vision through their impact on tear quality and production, which in turn leads to irritated, tired, and itchy eyes. If you are not producing enough tears, or their composition is subpar and they evaporate too quickly, your eyes wont be properly lubricated. The longer these symptoms are present, the harder it will be to focus and see clearly.

    Who Gets Dry Eye

    Dry eye can affect anyone, but is more common as we get older because we produce a smaller volume of tears. Dry eye is particularly common in postmenopausal women and people with arthritis.Some medications can trigger dry eye, as can some general health conditions. People with dry eyes typically find it difficult to wear contact lenses. They may also have more problems in air-conditioned environments such as offices or supermarkets.There is no cure for dry eye, but its symptoms can be alleviated.

    How Do Dry Eyes Lead To Blurry Vision

    Why Dry Eyes Cause Blurry Vision – 3 Reasons, And 3 Home Remedies

    Eyes usually benefit from a microscopic film of lubrication from tears, which spread over the eye surface when we blink. The tear film consists of three layers:

    • Fat-based oil layer
    • Thin, watery fluid layer

    This combination keeps eyes moist, which in turn assures clear vision .

    Any change in the tear film layers leads to uncomfortable dry eyes.

    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.

    Blurry Eyes & Other Symptoms

    Along with its large number of causes, dry eye syndrome has multiple symptoms that can interfere with eye comfort and function. Blurred vision is one, and other symptoms can include:

    • The feeling that theres something in the eye
    • Slight mucus discharge in or around the eye
    • Discomfort when wearing contact lenses

    These symptoms can be indicative of dry eye, but also of other eye conditions and diseases that may be more serious. Visit your optometrist to make sure your vision is guarded whenever symptoms occur.

    What Causes Blurred Vision

    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.

    Symptoms That May Come With Blurry Vision

    Top 5 Causes of Blurred Vision, Symptoms, and Treatment

    Blurry vision, in the main, is an inconvenience. However, if left untreated, it can lead to a number of other symptoms as well. This is true whether you are suffering from blurry vision due to DES or due to another condition that affects the eye. These other symptoms include:

    • Spots and floaters
    • Red bloodshot eyes
    • Poor near vision

    The eyes are very complex organs and, besides the skin, the only ones that are directly exposed to the environment. As such, there are many different things that can affect them as well. Unfortunately, for many reasons, we have a tendency to self-diagnose and self-medicate, but this is never a good option with blurry vision.

    Causes & Risk Factors

    Dry eyes can occur when tear production and drainage are not in balance. People with dry eyes either do not produce enough tears or their tears are of a poor quality:

    • Inadequate amount of tears. Tears are produced by several glands in and around the eyelids. Tear production tends to diminish with age, with various medical conditions or as a side effect of certain medicines. Environmental conditions, such as wind and dry climates, can also decrease tear volume due to increased tear evaporation. When the normal amount of tear production decreases or tears evaporate too quickly from the eyes, symptoms of dry eye can develop.
    • Poor quality of tears. Tears are made up of three layers: oil, water, and mucus. Each component protects and nourishes the front surface of the eye. A smooth oil layer helps prevent evaporation of the water layer, while the mucin layer spreads the tears evenly over the surface of the eye. If the tears evaporate too quickly or do not spread evenly over the cornea due to deficiencies with any of the three tear layers, dry eye symptoms can develop.

    Dry eyes can develop for many reasons, including:

    Advanced dry eyes may damage the front surface of the eye and impair vision.

    Can Dry Eye Syndrome Cause Blurry Vision

    In short, yes blurry vision is a common symptom of dry eye syndrome. In addition to keeping the cornea healthy and lubricated, tears are an important part of our ability to see. In order to have clear vision, your tears must have the correct balance of water, oils, and mucus that enables the tear film to spread across the cornea. If your tear quality is compromised, your tears may evaporate too easily, become too oily, or be filled with mucus. Any of these issues will prevent the tears from spreading over the cornea and will hinder your ability to see clearly. It will likely also cause irritation and discomfort in your eyes.

    To temporarily help increase your vision that has been affected by poor tear quality, you can try blinking fully and frequently. Blinking will re-spread the tear film across the cornea. However, if the problem persists, dont hesitate to consult a doctor to evaluate whether you have dry eye syndrome and to determine what the best treatment is to restore clear vision.

    The Connection Between Dry Eyes & Blurry Vision

    To answer the eponymous question: Yes, dry eyes can lead to blurry vision, but the next question we should be asking is why?

    There are various reasons for how dry eyes can develop, but specific issues could lead to visual problems like blurry vision. Some of these issues can include:

    • Poor contact lens fittings

    What Are The Most Common Causes Of Blurred Vision That Gets Worse Over Time

    Watery, blurry, stinging vision – It may be Dry Eyes!

    Blurry vision is a common symptom with many potential causes, including very common ones like refractive errors and dry eyes. Here are just some of the possible causes:

    Refractive errors that cause blurred vision

    A refractive error is a disorder that happens when the eyes cant focus images correctly. The term includes these conditions: astigmatism, farsightedness and nearsightedness. You can often correct these conditions with eyeglasses, contact lenses or surgery. Refractive errors are the most common cause of blurred vision.

    Dry eye syndrome that causes blurred vision

    Another common cause of blurred vision is dry eyes. You could have dry eyes if your vision improves when you blink. Dry eye syndrome can cause what seems to be a film. The syndrome may also cause itching, redness and pain. Treatment will include the use of artificial tears.

    Age-related macular degeneration that causes blurred vision

    Age-related macular degeneration is the most common cause of vision loss in older Americans. The condition affects your central vision so that you cant see what is directly in front of you. It can affect one or both eyes.

    Diabetic retinopathy that causes blurred vision

    Diabetic retinopathy can affect anyone who has diabetes. The condition can reduce your vision even to the point of blindness. It weakens the blood vessels in your retina.

    How To Talk To Your Doctor

    You are not alone in your vision problems with dry eye. A big part of getting the answers and care you need is telling your doctor how you are feeling. Dry eye disease is long-term and seems to get worse over time. Talking to your doctor about how you feel will hopefully get you closer to the treatment you need.

    Can You Prevent Blurry Vision

    There are many cases in which blurry vision cannot be prevented. Near- or farsightedness, for instance, usually presents itself at a very early age and is genetic . At the same time, there are certain things that you can do in order to prevent it. Keeping your eyes moist and well-lubricated, or preventing dry eye, in other words, is one of the most important things. Secondly, you must go for regular eye examinations. If there are any underlying health conditions that are causing the blurry vision, they will be picked up on then. Furthermore, if it is caused by dry eye, you will be able to identify this and take measures to avoid it. The table below shows just how often you should have your eyes professionally checked.

    Stringy Mucus In The Eye

    This symptom is more common in people with moderate to severe dry eye and may occur in combination with other conditions, like an infection or allergy.

    People with dry eye who dont produce enough tears or oil to protect the tear film can experience friction or strain when they blink. When this happens, the tear film tries to make mucus in order to make up for the lack of moisture in your eyes.

    The mucus usually looks like a stringy discharge coming out of your eyes. If you begin to see mucus coming out of your eyes, try to remove it gently with a clean tissue instead of rubbing your eyes. Too much rubbing can cause inflammation in your eyes and worsen your condition.

    When Is Blurry Vision A Medical Emergency

    Blurry Vision Diagnosis &  Treatment

    Sometimes, blurred vision in one eye can signify a serious condition that needs emergency treatment. Its important to be aware of the signs of these conditions so you know when to seek medical care.

    • Severe headache that comes on quickly
    • A headache that follows a blow to the head
    • Loss of consciousness
    • Difficulty raising one or both arms

    People with diabetes should seek immediate medical care if they experience:

    • Sudden changes in vision, such as flashes of light
    • An unusual increase in eye floaters
    • Sudden vision loss, especially after coughing or sneezing
    • Seeing shadows, curtains, or cobwebs in your field of vision

    What To Do If You Experience Blurry Vision

    If you experience blurry vision for any significant period of time, you should see an eye doctor, who will be able to best determine whether you have dry eye or another condition.

    One thing you can try, however, is blinking fully and frequently for several seconds. Because blinking re-spreads the tear film across the surface of the eyes, increased blinking can temporarily relieve your blurry vision. However, depending on the cause, this is unlikely to correct the underlying problem, and seeking professional advice remains the best option.

    Have Regular Eye Exams

    No matter what issue you might be experiencing with your eyes, the first step to getting the help you need is ensuring you have regular eye exams.

    Visiting our team regularly for routine exams helps look for potential issues before they lead to more serious symptoms, including dry eye. By detecting these problems early, we can provide you with personalized strategies that fit your eye health and lifestyle.

    Advanced Dry Eye Therapies

    If self-care therapies dont effectively treat your symptoms, your doctor might suggest more advanced, nonsurgical treatments, such as:

    • Medication adjustment: Certain drugs, such as antihistamines, antidepressants, birth control pills, and blood pressure medications can worsen dry eye symptoms. We can work with your primary care doctor or specialist to find an alternative. Make sure to talk with your doctor about all medications you are taking and continue taking them as prescribed until your doctor recommends a change.
    • Prescription eye drops: If over-the-counter artificial tears are not enough, prescription eye drops can help increase tear production and decrease inflammation.
    • Nonsteroidal anti-inflammatory drugs : Oral NSAIDs purchased over the counter may be used to help ease discomfort associated with dry eye disease.
    • Steroid eye drops: Dry eye disease triggers inflammation, which may require short-term use of steroid eye drops. These eye drops can help get the inflammation under control but should only be used for a short period of time due to potential side effects.

    At UT Southwesterns Advanced Dry Eye Specialty Clinic, our ophthalmologists and optometrists partner with experts from non-eye fields across the medical center to personalize treatment plans for dry eye that start with the patients underlying condition.
