Dry Eye in Seattle: Causes, Symptoms & Relief

Executive Summary & Key Takeaways

Seattle residents face unique challenges with dry eye symptoms due to the region’s distinctive climate patterns—from windy conditions that accelerate tear evaporation to seasonal indoor heating that creates dry environments. Understanding your symptoms and seeking proper professional evaluation can prevent complications and restore comfort through personalized treatment approaches that range from simple lifestyle modifications to advanced in-office therapies.

Understanding Dry Eye Symptoms

Dry eye disease affects millions of Americans, with recent studies indicating that an estimated 5% to 50% of the global population experiences dry eye symptoms, with women and older adults being more susceptible. For Seattle residents, this common condition can significantly impact daily activities from reading and computer work to driving, especially when compounded by the region’s environmental factors.

Bottom Line: Dry eye is a chronic, progressive condition that requires ongoing management rather than a one-time cure, similar to conditions like high blood pressure or diabetes.

The Science Behind Dry Eye

Dry eye disease occurs when your tear film—the protective layer covering your eye’s surface—becomes unstable or insufficient. According to the Tear Film and Ocular Surface Society (TFOS) Dry Eye Workshop II (DEWS II), dry eye is “a multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film, and accompanied by ocular symptoms, in which tear film instability and hyperosmolarity, ocular surface inflammation” create a cascade of problems.

Your tear film consists of three essential layers:

• Lipid (oil) layer: Produced by meibomian glands to prevent evaporation
• Aqueous (water) layer: Created by lacrimal glands for lubrication
• Mucin layer: Made by conjunctival cells to help tears adhere to the eye surface

When any of these layers becomes disrupted, dry eye symptoms develop.

Seattle’s Climate and Dry Eye Triggers

Seattle’s unique Pacific Northwest climate creates specific challenges for dry eye sufferers. The region’s combination of seasonal weather patterns, indoor heating systems, and urban environmental factors can exacerbate symptoms throughout the year.

Seasonal Impacts on Dry Eye

Winter Months: Symptoms tend to be worse on windy days and during the winter months due to dry indoor heat. Seattle’s heating systems reduce indoor humidity, while cold outdoor air holds less moisture, creating a double challenge for tear film stability.

Spring and Fall: Variable weather patterns with frequent wind can accelerate tear evaporation. Seattle’s average wind speeds during transitional seasons can particularly affect those with compromised tear production.

Summer: While generally milder, air conditioning usage and outdoor activities in sunny conditions can contribute to increased tear evaporation.

Urban Environmental Factors

Seattle’s urban environment presents additional challenges:

• Air pollution from traffic and industry
• Digital eye strain from the tech-heavy workforce
• Reduced blinking rates during screen-intensive work
• Indoor air quality is affected by building ventilation systems

Common Causes of Dry Eye Disease

Understanding the underlying causes of dry eye helps Seattle residents identify personal risk factors and make informed treatment decisions.

Primary Causes

Evaporative Dry Eye: Most people who experience dry eye symptoms have what is known as evaporative dry eye. Evaporative dry eye occurs when the tear film coating the eye evaporates too quickly because of insufficient oil (lipid) content. This is most often the result of a blockage in the Meibomian glands.

Aqueous Deficient Dry Eye: Occurs when tear glands produce insufficient quantities of tears, often related to:

• Age-related decrease in tear production
• Autoimmune conditions like Sjögren’s syndrome
• Hormonal changes, particularly in women
• Certain medications

Contributing Factors Specific to Seattle Residents

Demographics: Seattle’s aging population faces increased risk, as tear production tends to diminish as you get older. Dry eyes are more common in people over 50.

Gender: A lack of tears is more common in women, especially if they experience hormonal changes due to pregnancy, using birth control pills, or menopause.

Lifestyle Factors:

• Extended computer use in tech industry jobs
• Contact lens wear
• Air conditioning and heating exposure
• Dietary factors, including insufficient omega-3 fatty acids

Medical Conditions: Certain medical conditions, including Sjogren’s syndrome, allergic eye disease, rheumatoid arthritis, lupus, scleroderma, graft vs. host disease, sarcoidosis, thyroid disorders, or vitamin A deficiency.

Medications: Certain medicines, including antihistamines, decongestants, hormone replacement therapy, antidepressants, and medicines for high blood pressure, acne, birth control, and Parkinson’s disease.

Recognizing Dry Eye Symptoms

Dry eye symptoms can vary significantly between individuals and may not always be obvious initially. Understanding the full spectrum of symptoms helps Seattle residents identify when professional evaluation is needed.

Primary Dry Eye Symptoms

Classic Symptoms:

• Burning, irritation, and itching, as well as tearing or watering eyes
• Dryness – a constant sandy or scratchy sensation
• Eye pain or discomfort
• Blurred vision. One clue that blurred vision is due to dry eye is that it clears temporarily after blinking.

Paradoxical Symptoms: Watery eyes (counterintuitive, but a hallmark symptom) occur because the surface of the eye is dry and sends a signal to the brain to secrete more tears and moisturize the cornea. However, the mostly reflex tears that are secreted by the lacrimal and accessory lacrimal (tear) glands may be of poor quality.

Activity-Related Symptoms

Dry eye symptoms can be especially troublesome while reading, watching TV, and working on the computer—activities that are particularly relevant for Seattle’s professional workforce.

Environmental Trigger Dry Eye Symptoms

Symptoms often worsen with:

• Wind exposure (common in Seattle)
• Air conditioning or heating
• Smoke or air pollution
• Low-humidity environments

Progressive Nature of Symptoms

Dry eye is a chronic and progressive condition that affects quality of life by its host of ocular symptoms and its ability to impact patient productivity at work and home. Early recognition and treatment can prevent progression to more severe stages.

Professional Diagnosis and Evaluation

Accurate diagnosis requires professional evaluation, as dry eye symptoms can mimic other conditions, and self-diagnosis may lead to inappropriate treatment choices.

Comprehensive Dry Eye Assessment

Professional evaluation typically includes:

Medical History Review: We will inquire about the patient’s symptoms, such as dryness, irritation, redness, fluctuating vision, and sensitivity to light. Providing detailed information about the frequency and severity of symptoms can aid in the diagnosis.

Tear Film Analysis: The quality and quantity of the tear film are assessed through various tests, such as tear breakup time (TBUT), Schirmer’s test, and tear osmolarity measurement. These tests help determine the stability and production of tears.

Ocular Surface Examination: To diagnose dry eye, the doctor will look closely at your eyelids, check the quality of your tear film, and check for ocular inflammation.

Advanced Diagnostic Technology

Seattle eye care providers often utilize state-of-the-art diagnostic equipment:

• Tear film osmolarity testing
• Meibography to assess oil gland function
• Inflammatory marker testing
• Digital imaging of tear breakup patterns

Identifying Root Causes

A dry eye evaluation at Cannon EyeCare identifies root causes (e.g., tear quality or environmental factors) to create a tailored management plan. This personalized approach is crucial for effective long-term management.

Treatment Options for Seattle Residents

Treatment approaches have expanded significantly in recent years, offering Seattle residents multiple options ranging from conservative home care to advanced in-office procedures.

Conservative Management

Artificial Tears: In general, artificial tears remain a mainstay of treatment for dry eye symptoms. Many brands of artificial tears are available, and they vary in their composition, active ingredients, preservatives, etc. Patients with severe dry eyes are usually prescribed preservative-free artificial tears.

Home Care Treatments: Many cases of dry eye can be treated with home care steps, including eyelid cleaning products, dry eye masks, and artificial tears.

Warm Compress Therapy: Heat will soften the oils, allowing for easier release from the meibomian glands. Studies have proven that meibomian secretions melt at 32 – 45°C (89.6 – 113°F). It takes about 10 minutes for heat to fully penetrate the tarsal plates and reach 40°C at the inner eyelid.

Prescription Medications

Anti-inflammatory Treatments: When artificial tears do not reduce the symptoms of dry eyes, other medications such as topical cyclosporin (Restasis) or topical steroids may be prescribed. Topical cyclosporin is used twice daily and takes 6-12 weeks to have an effect.

Tear Stimulating Medications: Tear-stimulating eye drops that are prescribed to help increase your body’s natural tear production. Anti-inflammatory eye drops are used to reduce inflammation on the corneal and ocular surface.

Advanced In-Office Treatments

Intense Pulsed Light (IPL): Intense Pulsed Light (IPL) Therapy addresses the underlying inflammation associated with dry eye by unclogging the meibomian glands and encouraging healthy tear production.

Meibomian Gland Expression: Meibomian gland expression is a procedure that clears blocked oil glands, which prevents the rapid evaporation of tears.

LipiFlow Treatment: Lipiflow applies a gentle warm heat to the internal eyelids along with a thermal pulsation to gently and safely massage your eyelids. This combination of warmth and massage helps to unclog the glands that limit the quality of oil in the tears.

Punctal Plugs: Small devices inserted into the tear ducts, called punctal plugs, can block tear drainage, helping to keep the eye surface moist for longer.

Emerging Therapies

Recent advances include:

• Amniotic Extract Eye Drops: Containing nutrients and anti-inflammatory properties, amniotic extract eye drops have proven to help alleviate advanced dry eye symptoms in many people
• Radio Frequency Treatment: Radio Frequency (RF) Treatment – This stimulates your body into rejuvenating the oil glands back to working order. Results help your body to help itself maintain tearfilm and hydration on your eyeballs.

Treatment Success Rates

In most cases, we can significantly improve the symptoms of dry eye with adequate hydration, working on eyelid health, and the use of artificial tears or medicated drops. Our optometrists would rarely refer for surgical intervention.

Prevention Strategies

Preventing dry eye or minimizing symptom progression involves addressing modifiable risk factors and implementing protective lifestyle habits.

Environmental Modifications

Indoor Air Quality:

• Use humidifiers during heating season (especially important in Seattle winters)
• Position fans and air vents away from direct eye exposure
• Add moisture to the air. In winter, a humidifier can add moisture to dry indoor air.

Eye Protection:

• Consider wearing wraparound sunglasses or other protective eyewear. Safety shields can be added to the tops and sides of eyeglasses to block wind and dry air.r
• Use computer glasses with the anti-reflective coating

Digital Eye Strain Prevention

The 20-20-20 Rule: Take eye breaks during long tasks. If you’re reading or doing another task that requires visual concentration, take periodic eye breaks. Close your eyes for a few minutes. Or blink repeatedly for a few seconds to help spread your tears evenly over your eyes.

Workspace Optimization:

• Position screens at or slightly below eye level
• Maintain an arm’s length distance from screens
• Ensure adequate lighting to reduce glare
• Use artificial tears during extended computer sessions

Lifestyle Modifications

Dietary Considerations: Eating a diet that is low in vitamin A, which is found in liver, carrots, and broccoli, or low in omega-3 fatty acids, which are found in fish, walnuts, and vegetable oil, can contribute to dry eye symptoms.

Hydration: Maintaining adequate systemic hydration supports tear production.

Sleep Quality: Proper sleep hygiene supports overall eye health and tear production.

When to Seek Professional Care

Understanding when symptoms require professional attention can prevent complications and improve treatment outcomes.

Red Flag Symptoms

Seek immediate professional evaluation for:

• Sudden onset of severe dry eye symptoms
• Eye pain that doesn’t improve with artificial tears
• Significant vision changes
• Signs of infection (discharge, severe redness)
• Symptoms affecting daily activities or work productivity

Early Intervention Benefits

See your health care provider if you’ve had prolonged signs and symptoms of dry eyes, including red, irritated, tired, or painful eyes. Your provider can take steps to determine what’s bothering your eyes or refer you to a specialist.

Potential Complications

Yes—chronic dry eye can lead to corneal scarring or infections if untreated. Early evaluation at Cannon EyeCare Seattle helps prevent complications through timely, targeted therapies.

People who have dry eyes may experience these complications: Eye infections. Your tears protect the surface of your eyes from infection. Without adequate tears, you may have an increased risk of eye infection. Damage to the surface of your eyes. If left untreated, severe dry eyes may lead to eye inflammation, abrasion of the corneal surface, corneal ulcers, and vision loss.
