Why Are My Eyes Dry?

Causes, Symptoms, and Treatment of Dry Eyes

Dry eye is a condition in which your eyes do not have enough quality tears to lubricate and nourish the eye surface. Tears are essential for maintaining eye health and providing clear vision.

Dry eyes occur when:

• Tears evaporate too quickly, or

• The eyes produce too few tears, or

• There is an imbalance in the tear film layers.

The tear film has three layers: mucin, aqueous (watery), and lipid (oil). A problem in any of these layers can lead to dry eye.

Anyone can develop dry eyes, but it is more common in older adults and women. It can affect one or both eyes.

What Causes Dry Eyes?

Dry eyes usually occur due to imbalance in tear production, drainage, or tear composition.

Common Causes

Aging: Tear production naturally decreases with age.

Hormonal changes: Pregnancy, menopause, and contraceptive use increase risk.

Medications: Antihistamines, antidepressants, blood pressure drugs, and some eye drops can reduce tear production.

Environmental factors: Smoke, wind, dust, and dry air increase tear evaporation.

Medical conditions:

• Diabetes

• Rheumatoid arthritis

• Sjögren’s syndrome

• Thyroid disease

• Vitamin A deficiency

Eyelid problems: Incomplete blinking prevents proper tear distribution.

Other Risk Factors

• Prolonged screen use

• Previous eye surgery (like LASIK)

• Long-term contact lens use

• Omega-3 deficiency

Symptoms of Dry Eye

Common symptoms include:

• Burning or stinging sensation

• Itchy eyes

• Feeling of a foreign body in the eye

• Redness

• Blurred vision

• Excess watering

• Light sensitivity

• Difficulty wearing contact lenses

• Eyelids sticking together in the morning

Symptoms often worsen after reading, screen use, or driving, and usually become worse later in the day.

If untreated, dry eye can lead to infections and vision problems.

How Is Dry Eye Diagnosed?

Eye care professionals diagnose dry eye through a comprehensive eye examination, including:

• Medical and symptom history

• Eyelid and corneal examination

• Tear evaluation using special dyes

• Additional tear tests if needed

Treatment of Dry Eyes

Treatment depends on the underlying cause but mainly focuses on keeping the eyes lubricated.

Common Treatments

• Artificial tear eye drops

• Lubricating ointments (especially at bedtime)

• Eyelid hygiene and cleaning

• Treating underlying inflammation

Self-Care Tips to Reduce Dry Eyes

• Blink frequently, especially during screen use

• Take regular breaks from digital devices

• Avoid smoke, dust, and dry air

• Use protective glasses outdoors

• Stay well hydrated

• Maintain proper contact lens hygiene

Cold compress helps with itching, while warm compress helps with oil gland blockage.

How to Prevent Dry Eyes

• Wash eyes gently with clean water

• Drink plenty of fluids

• Get adequate sleep

• Limit screen time

• Wear protective eyewear when needed

Why Do Eyes Feel Dry After Waking Up?

This may happen because:

• Eyelids do not fully close during sleep

• Exposure to fan or air conditioner overnight

• Certain nighttime medications

Key Takeaway

Dry eye is a very common condition but is usually manageable with proper care, lifestyle changes, and timely treatment. If symptoms persist, consult an eye care professional early.
