Chronic Dry Eye: Causes You Didn’t Know About

Dry, irritated eyes are often blamed on too much screen time or getting older. For many adults, dry eye symptoms become persistent and begin affecting daily comfort. If your eyes burn, sting, water excessively, or feel gritty throughout the day, there may be underlying causes affecting your tear quality and eye health.

Many adults notice blurry vision after screen time, especially after long hours at work or extended use of digital devices. What surprises many patients is that chronic dryness is not always caused by a lack of tears. In many cases, the problem is linked to inflammation, blocked oil glands, or environmental stress. Understanding these lesser-known triggers can help you find lasting relief and protect your vision.

Why Chronic Dry Eye Happens

Tears help maintain eye comfort while protecting the overall health of the eyes. They help protect the cornea, clear away debris, and support sharp vision. When the tear film becomes unstable, the eyes can dry out faster than normal.

Healthy tears contain three essential layers:

• An oily layer that slows evaporation
• A watery layer that provides moisture
• A mucus layer that helps tears spread evenly

When the tear film becomes unstable, irritation and visual discomfort can develop.

The Canadian National Institute for the Blind (CNIB) reports that dry eye symptoms are becoming more common, especially among adults who spend extended time on digital devices.

Hidden Dry Eye Syndrome Causes

Several everyday factors may contribute to chronic dryness without people realizing it.

Meibomian Gland Dysfunction

One of the most overlooked causes is meibomian gland dysfunction. Small glands located along the edges of the eyelids release oils that help slow tear evaporation. When these glands become blocked or inflamed, the tear film loses stability.

Common symptoms include:

• Burning or stinging eyes
• Redness
• Watery eyes
• Light sensitivity
• Fluctuating vision

Ironically, dry eyes can sometimes trigger excessive tearing because the eyes attempt to compensate for irritation.

Too Much Screen Time

Digital eye strain has become increasingly common in Canada due to work and lifestyle habits. People blink less frequently while reading, scrolling, or working on screens, which prevents tears from spreading properly across the eye surface.

Some people notice symptoms such as:

• Eye fatigue
• Temporary blurred vision
• Dryness later in the day
• Difficulty focusing

Taking regular breaks throughout the day can support ocular surface health and reduce eye strain.

Environmental Conditions

Canada’s climate can also contribute to dryness. Indoor heating during winter, cold winds, and dry air may worsen symptoms.

You may notice increased irritation:

• During colder months
• In heated indoor spaces
• While driving with vents directed at the face
• On flights or in low-humidity environments

Repeated exposure to dry or windy conditions may worsen irritation in sensitive eyes.

Contact Lens Wear

Some contact lens wearers experience dryness because lenses can interfere with the natural tear film. Long-term use may also contribute to irritation in certain individuals.

Adjusting lens materials or reducing wear time may improve comfort for some patients.

Medications And Health Conditions

Certain medications may reduce tear production, including:

1. Antihistamines
2. Some antidepressants
3. Blood pressure medications
4. Acne treatments
5. Hormonal therapies

Health conditions such as diabetes, rosacea, and autoimmune disorders may also increase the risk of chronic dry eye symptoms.

Understanding Evaporative Dry Eye

Not all dry eye cases are caused by insufficient tears. One of the most common forms is evaporative dry eye, in which tears evaporate too quickly from the surface of the eye.

Signs Of Evaporative Dry Eye

• Burning or scratchy eyes
• Symptoms that worsen later in the day
• Excessive watering
• Fluctuating vision
• Discomfort while reading or driving

Many modern treatment approaches focus on evaporative dry eye solutions because this form of dryness is becoming more common among adults who use screens regularly.

How Optometrists Assess Chronic Dry Eye

A dry eye assessment involves more than checking visual acuity. Optometrists examine tear quality, eyelid function, gland health, and signs of inflammation.

A comprehensive evaluation may include:

• Tear film testing
• Eyelid assessment
• Imaging of oil glands
• Corneal surface examination
• Review of medications and lifestyle habits

An experienced Mahogany eye doctor can determine whether symptoms are linked to tear evaporation, inflammation, environmental factors, or reduced tear production.

Options For Chronic Dry Eye Relief

Treatment depends on the underlying cause. Mild cases may improve with simple lifestyle adjustments, while more persistent symptoms may require advanced therapies.

Everyday Habits That Support Eye Comfort

Daily habits can play an important role in improving eye comfort. 

Helpful Eye Care Tips

• Follow the 20-20-20 rule during screen use
• Drink enough water throughout the day
• Use a humidifier indoors
• Clean eyelids gently each day
• Wear sunglasses outdoors to protect against the wind

Warm compresses may also help improve oil flow from blocked glands.

Advanced In-Clinic Treatments

When symptoms continue despite home care, professional treatment may help address the root cause more effectively.

LipiFlow Therapy

One advanced option is LipiFlow dry eye therapy, which uses controlled heat and gentle pressure to help clear blocked oil glands in the eyelids.

The treatment is designed to improve oil flow into the tear film, so tears remain stable for longer. Many patients with gland-related dryness find this approach helpful when lubricating drops alone are not enough.

Other Professional Treatments May Include

• Prescription eye drops
• Specialized eyelid hygiene treatments
• Intense pulsed light therapy
• Therapeutic artificial tears
• Nutritional guidance

Because every patient’s tear film is different, treatment plans should be personalized.

When Dry Eye Symptoms Should Be Evaluated

While temporary dryness can happen occasionally, persistent irritation may require professional evaluation.

Book an eye exam if you experience:

• Persistent burning or irritation
• Fluctuating vision
• Difficulty wearing contact lenses
• Ongoing redness
• Symptoms affecting daily activities

Leaving chronic dryness untreated may increase inflammation and affect long-term eye comfort.

Final Thoughts

Understanding the lesser-known causes of dry eye syndrome can help patients recognize when symptoms warrant professional attention. Chronic dryness is often connected to tear instability, inflammation, lifestyle habits, or gland dysfunction rather than simply tired eyes.
