Dry Eye Syndrome (Dry Eye Disease) is a common condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. Tears are essential for lubricating the eye, maintaining clear vision, protecting against infection, and keeping the surface of the eye healthy.
Causes
Dry eye syndrome can result from one or more of the following:
Reduced tear production
Aging (more common in older adults)
Hormonal changes (e.g., menopause)
Autoimmune diseases such as rheumatoid arthritis or Sjögren syndrome
Certain medications, including antihistamines, antidepressants, diuretics, and some blood pressure medications
Increased tear evaporation
Dysfunction of the oil-producing (meibomian) glands in the eyelids
Prolonged screen use with reduced blinking
Dry, windy, or air-conditioned environments
Contact lens wear
Incomplete eyelid closure
Poor tear quality
An imbalance in the tear film (oil, water, and mucus layers), causing tears to become unstable and evaporate rapidly.
Symptoms
People with dry eye syndrome may experience:
Dryness or a gritty, sandy sensation
Burning or stinging eyes
Redness
Itching or irritation
Excessive tearing (a reflex response to dryness)
Blurred or fluctuating vision that improves with blinking
Light sensitivity (photophobia)
Eye fatigue, especially after reading or using digital devices
Difficulty wearing contact lenses
Stringy mucus around the eyes
Risk Factors
Factors that increase the likelihood of developing dry eye include:
Age over 50 years
Female sex, particularly after menopause
Long hours of digital screen use
Contact lens use
Previous eye surgery (e.g., LASIK)
Smoking
Low humidity or air-conditioned environments
Medical conditions such as diabetes, thyroid disease, or autoimmune disorders
Diagnosis
An eye care professional may diagnose dry eye syndrome by:
Taking a detailed history of symptoms
Examining the ocular surface using a slit lamp
Measuring tear production (e.g., Schirmer test)
Assessing tear film stability using the tear breakup time (TBUT) test
Applying dyes such as fluorescein or lissamine green to identify damage to the ocular surface
Evaluating the function of the meibomian glands
Treatment
Treatment depends on the underlying cause and severity.
Lifestyle and environmental measures
Blink more frequently, especially during screen use.
Follow the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds).
Use a humidifier.
Avoid direct airflow from fans or air conditioners.
Stay well hydrated.
Medications and therapies
Artificial tears (lubricating eye drops)
Lubricating gels or ointments, especially at night
Prescription anti-inflammatory eye drops for moderate to severe disease
Warm compresses and eyelid hygiene for meibomian gland dysfunction
Omega-3 fatty acid supplementation (may help some people)
Punctal plugs to reduce tear drainage in selected patients
Possible Complications
If left untreated, dry eye syndrome can lead to:
Persistent eye discomfort
Reduced quality of life
Difficulty reading, driving, or using digital devices
Damage to the corneal surface
Increased risk of eye infections
Corneal ulcers or scarring in severe cases
Prognosis
Dry eye syndrome is usually a chronic but manageable condition. Most people achieve good symptom control through a combination of lifestyle changes, lubricating eye drops, and treatment of any underlying causes. Regular follow-up with an eye care professional is recommended, especially for moderate to severe cases or when symptoms worsen despite treatment.
