Dry eye syndrome is a common eye condition that can affect people of all ages. It occurs when the eyes do not produce enough tears, the tears evaporate too quickly, or the tear film does not function properly. While occasional dryness may seem minor, persistent symptoms can interfere with reading, computer use, driving, work, and everyday comfort.

For people living in Phoenix, Arizona, dry eye symptoms can be especially noticeable because the region's hot, dry climate, strong sunlight, dust, and indoor air conditioning can contribute to tear evaporation and eye irritation.

Understanding the causes, symptoms, and treatment options for dry eye can help you take steps toward healthier, more comfortable eyes.

What Is Dry Eye Syndrome?

Dry eye syndrome, also called dry eye disease, occurs when the eyes cannot maintain a healthy tear film. Tears are essential for more than simply keeping the eyes wet. They help lubricate the eye's surface, wash away debris, protect against infection, and provide a smooth optical surface for clear vision.

A healthy tear film contains several components, including:

Oil (lipid) layer: Helps prevent tears from evaporating too quickly.
Water (aqueous) layer: Provides moisture and contains substances that nourish and protect the eye.
Mucus (mucin) layer: Helps tears spread evenly across the eye's surface.

When the balance of this tear film is disrupted, dry eye symptoms can develop.

What Causes Dry Eye Syndrome?

Dry eye does not have one single cause. Several factors can affect tear production, tear quality, or tear evaporation.

1. Insufficient Tear Production

Some people do not produce enough tears to adequately lubricate the surface of their eyes. Tear production can decrease with age and may also be affected by certain medical conditions, medications, or inflammation.

2. Excessive Tear Evaporation

Tears can evaporate too quickly when the protective oily layer of the tear film is inadequate. This is often associated with problems involving the meibomian glands, which are tiny oil-producing glands located along the eyelids.

Environmental conditions can also increase evaporation. Hot temperatures, dry air, wind, fans, and air conditioning may all contribute to faster tear evaporation.

3. Prolonged Screen Use

Spending long periods looking at computers, tablets, or smartphones can contribute to digital eye strain and dry eye symptoms. When concentrating on a screen, people often blink less frequently or incompletely.

Reduced blinking means tears may not spread across the eye's surface as effectively.

4. Contact Lens Wear

Contact lenses can contribute to dryness in some individuals, particularly when lenses are worn for extended periods or when the lens material or fit is not appropriate for the patient's eyes.

People who experience persistent discomfort while wearing contacts may benefit from a professional contact lens evaluation.

5. Aging

Dry eye becomes more common as people get older. Changes in tear production and the quality of the tear film can make the eyes more susceptible to dryness and irritation.

6. Medications

Certain medications may contribute to dry eye symptoms. These can include some allergy medications, antidepressants, blood pressure medications, and other commonly used drugs.

If you suspect a medication is contributing to dry eyes, speak with your healthcare professional rather than stopping it on your own.

7. Eyelid or Meibomian Gland Problems

The meibomian glands produce oils that help slow tear evaporation. If these glands become blocked or do not function properly, the tear film may become unstable.

This is one reason an eye doctor may examine the eyelids and tear film when evaluating chronic dry eye.

8. Environmental Conditions

Phoenix's desert environment can be challenging for people prone to dry eyes. Heat, low humidity, wind, dust, and air conditioning may all increase eye discomfort.

Spending time outdoors in windy or dusty conditions may make symptoms more noticeable.

Common Symptoms of Dry Eye

Dry eye symptoms can range from mild irritation to significant discomfort.

Common symptoms include:

Dry, gritty, or sandy sensations
Burning or stinging
Redness
Itching or irritation
Watery eyes
Blurred or fluctuating vision
Light sensitivity
Eye fatigue
Difficulty wearing contact lenses
A sensation that something is stuck in the eye
Increased discomfort while reading or using screens

Interestingly, watery eyes can also be a symptom of dry eye. When the eye becomes irritated, it may respond by producing a sudden burst of watery tears. However, these reflex tears may not contain the same balanced components needed for long-lasting lubrication.

When Should You See an Eye Doctor?

Occasional eye dryness may improve with simple lifestyle changes. However, persistent or worsening symptoms deserve professional attention.

Consider scheduling an eye examination if:

Dryness continues despite using artificial tears
Your eyes frequently burn or sting
You experience recurring redness
Your vision fluctuates throughout the day
Contact lenses become increasingly uncomfortable
You regularly experience excessive tearing
Symptoms interfere with work, reading, driving, or sleep
You frequently need to rub your eyes

An eye doctor can determine whether dry eye is the underlying problem and identify contributing factors.

How Is Dry Eye Diagnosed?

A comprehensive eye examination can help determine the cause and severity of dry eye.

Depending on your symptoms, your eye doctor may evaluate:

Tear Production

Special tests can estimate how much tear fluid your eyes produce.

Tear Film Stability

Your eye doctor may evaluate how long your tears remain stable on the eye's surface between blinks.

Eye Surface Health

The cornea and conjunctiva can be examined for signs of irritation, inflammation, or damage associated with chronic dryness.

Eyelid and Meibomian Gland Function

Examining the eyelids and oil-producing glands can help determine whether meibomian gland dysfunction is contributing to excessive tear evaporation.

A proper diagnosis is important because dry eye treatment works best when it addresses the underlying cause rather than simply treating the symptom.

Dry Eye Treatment Options

Treatment depends on the severity and cause of your symptoms. Your eye doctor may recommend one or more of the following approaches.

1. Artificial Tears

Over-the-counter lubricating eye drops are often used to temporarily relieve mild dry eye symptoms.

Preservative-free artificial tears may be recommended for people who need to use drops frequently, as some preservatives can cause additional irritation in sensitive eyes.

2. Warm Compresses

Warm compresses may help soften oils within the meibomian glands and encourage better oil flow.

Your eye-care professional can provide guidance on appropriate eyelid hygiene and warm-compress techniques.

3. Eyelid Hygiene

Keeping the eyelids clean can be an important part of managing certain forms of dry eye, particularly when eyelid inflammation or meibomian gland dysfunction is involved.

Your eye doctor can recommend an appropriate eyelid-care routine based on your condition.

4. Prescription Eye Drops

When inflammation contributes to chronic dry eye, an eye doctor may recommend prescription medications designed to help manage inflammation and improve tear production or tear-film stability.

Prescription treatment should be selected based on an individual's symptoms, medical history, and examination findings.

5. Punctal Plugs

Punctal plugs are tiny devices that can be placed into the tear drainage openings. They help slow the drainage of tears from the eye, allowing natural tears and lubricating drops to remain on the eye's surface longer.

They may be considered for certain patients with inadequate tear retention.

6. Specialty Contact Lenses

Some patients with moderate-to-severe ocular surface disease may benefit from specialty contact lens options.

Scleral lenses are larger-diameter lenses that vault over the cornea and rest on the white part of the eye. They hold a reservoir of fluid over the cornea, which can provide continuous hydration and improve comfort and vision for appropriately selected patients.

Scleral lenses may be especially helpful for people who have significant dryness, irregular corneas, or difficulty achieving comfortable vision with conventional contact lenses.

7. In-Office Dry Eye Treatments

For patients with persistent symptoms, an eye-care professional may recommend specialized in-office treatments based on the underlying cause.

These treatments may target meibomian gland dysfunction, inflammation, or other factors affecting tear-film stability.

A customized evaluation is important before selecting an in-office treatment.

How to Manage Dry Eyes at Home

In addition to professional treatment, several daily habits may help reduce symptoms.

Follow the 20-20-20 Rule

If you spend a lot of time on digital devices, periodically look away from your screen and focus on something farther away.

Blink More Often

Make a conscious effort to blink fully and regularly while reading or working on a computer.

Take Screen Breaks

Long, uninterrupted periods of screen use can increase eye fatigue and dryness. Short breaks can give your eyes an opportunity to rest and blink naturally.

Stay Hydrated

Maintaining adequate hydration supports overall health and may help support normal tear production.

Use a Humidifier

Indoor air conditioning can make the air feel dry. A humidifier may help improve indoor humidity and make the environment more comfortable for people prone to dry eyes.

Protect Your Eyes Outdoors

Sunglasses that provide good coverage can help reduce exposure to wind, dust, and intense sunlight.

Avoid Direct Airflow

Try not to position fans or air-conditioning vents so that air blows directly toward your eyes.

Give Your Eyes Regular Breaks

If your eyes become tired or uncomfortable during work, reading, or screen use, take short breaks and allow yourself to blink normally.

Dry Eye and Contact Lenses

Contact lens wearers may be particularly aware of dry eye symptoms.

Dryness can cause lenses to feel uncomfortable, become difficult to wear for extended periods, or contribute to fluctuating vision.

If you routinely remove your contacts because your eyes feel dry or irritated, do not assume that discomfort is something you simply have to tolerate. An eye-care professional can assess your tear film, eyelids, cornea, and lens fit and determine whether another lens option may be more appropriate.

For patients with significant ocular surface issues, specialty lenses such as scleral lenses may provide an alternative to traditional contact lenses.

Can Dry Eye Be Prevented?

Not every case of dry eye can be prevented, particularly when age, medications, or underlying health conditions play a role. However, healthy eye-care habits can help reduce symptoms and support ocular comfort.

Consider making these habits part of your daily routine:

Blink regularly during screen use.
Take frequent breaks from digital devices.
Avoid direct airflow toward your eyes.
Wear protective sunglasses outdoors.
Maintain good eyelid hygiene when recommended.
Stay adequately hydrated.
Follow your eye doctor's treatment plan.
Schedule routine comprehensive eye examinations.

Dry Eye in Phoenix: Why Climate Matters

Phoenix residents experience environmental conditions that can make dry eye symptoms more noticeable. The combination of hot temperatures, low humidity, dust, wind, and frequent indoor air conditioning can increase tear evaporation.

This does not mean everyone living in Phoenix will develop dry eye, but people who already have tear-film instability may notice symptoms more frequently.

If your eyes feel dry, gritty, irritated, or tired throughout the day, an eye examination can help determine whether environmental factors are contributing to the problem or whether an underlying condition requires treatment.

Why Professional Dry Eye Care Matters

Dry eye is not simply a matter of needing more eye drops. Different patients can have very different causes of dryness.

For one person, insufficient tear production may be the primary issue. For another, meibomian gland dysfunction or excessive tear evaporation may be responsible. Screen habits, medications, contact lens wear, eyelid problems, and environmental conditions can also play a role.

That is why a personalized evaluation is important.

A comprehensive assessment can help identify the factors contributing to your symptoms and create a treatment plan designed around your specific needs.

Final Thoughts

Dry eye syndrome is common, but persistent symptoms should not be ignored. Burning, redness, fluctuating vision, excessive tearing, irritation, and contact lens discomfort can all be signs that your eyes are struggling to maintain a healthy tear film.

The good news is that there are many ways to manage dry eye. Depending on the cause and severity, treatment may include lifestyle changes, artificial tears, eyelid care, prescription medications, punctal plugs, specialty contact lenses, or in-office treatments.
