PATIENT EDUCATION
Dry Eye Syndrome: Causes, Symptoms & Treatment
Dry eye occurs when the eyes do not make enough tears or when the tears evaporate too quickly. Identifying the cause is the first step toward lasting relief.
Pain or persistent vision loss needs evaluation
Dry eye can blur vision, but the blur often fluctuates or improves with blinking. Seek prompt care for significant pain, marked light sensitivity, a corneal white spot, injury, discharge, or vision that remains reduced.
WHY EYES FEEL DRY
The tear film must remain stable between blinks
Healthy tears contain water, oils, mucus, proteins, and other protective components. Dry eye develops when tear production is insufficient, the oily layer is inadequate, or the ocular surface becomes inflamed. Many patients have more than one contributing factor.
Evaporative dry eye
Tears evaporate too quickly, often because the meibomian oil glands are blocked or functioning poorly. Incomplete blinking and prolonged screen use may contribute.
Aqueous-deficient dry eye
The lacrimal glands do not produce enough of the watery portion of tears. Age, medication, autoimmune disease, and other health conditions can contribute.
Mixed dry eye
Features of both reduced tear production and excess evaporation are common. Treatment may need to address the eyelids, glands, inflammation, and environment.
Neuro-sensory changes
Corneal nerves help regulate tearing and sensation. Symptoms and visible surface findings do not always match, especially after surgery or with chronic disease.
Common symptoms
- Burning, stinging, or scratchiness
- A gritty or foreign-body sensation
- Watering or reflex tearing
- Redness
- Fluctuating blur, especially with reading or screens
- Light sensitivity
- Contact-lens discomfort
- Tired or heavy-feeling eyes
Common contributors
- Meibomian gland dysfunction or blepharitis
- Age and hormonal changes
- Contact lenses
- Screen use and incomplete blinking
- Dry, windy, smoky, or air-conditioned environments
- Antihistamines, antidepressants, blood-pressure medicines, and other medications
- Autoimmune, thyroid, or systemic disease
- Prior eye surgery or incomplete eyelid closure
DIAGNOSIS
Dry-eye testing looks beyond symptoms alone
Your clinician may evaluate the eyelids, blink pattern, tear-film stability, corneal staining, tear production, and meibomian gland openings. Imaging of the oil glands, tear osmolarity, inflammatory markers, or other tests may be used when they will change the treatment plan.
Not every patient needs every test. The goal is to identify the dominant causes and measure how the surface responds over time.
TREATMENT
Treatment is built around the cause
Daily surface support
Artificial tears, gels, ointments, humidification, screen breaks, improved blinking, hydration, and environmental protection can reduce symptoms.
Eyelid and gland care
Warm compresses, gentle lid cleansing, prescription medication, or in-office treatment may improve meibomian gland function.
Prescription eye drops
Anti-inflammatory or tear-stimulating medicines may be used for ongoing disease. The best option depends on the ocular surface and medical history.
Punctal plugs
Small plugs can slow tear drainage in selected patients. Surface inflammation is often addressed first.
Advanced surface protection
Serum tears, scleral lenses, amniotic membrane, moisture chambers, or other treatments may be considered for more severe disease.
Treating underlying problems
Allergy, blepharitis, Demodex, rosacea, eyelid position, medication effects, and systemic disease may need attention as part of the plan.
COMMON QUESTIONS
Dry eye FAQ
Why do dry eyes water?
An irritated surface can trigger reflex tearing. These watery tears may not contain enough oil to remain on the eye.
Are all artificial tears the same?
No. Formulations differ in viscosity, oils, preservatives, and intended frequency. Your clinician can recommend a type based on the tear-film problem.
Can dry eye be cured?
Some causes improve when a trigger is removed, but many forms require long-term management. The plan can be adjusted as symptoms and findings change.
Can contact lenses worsen dry eye?
They can increase evaporation or discomfort. Lens material, wearing time, care solution, and the underlying surface condition all matter.
