Dry eye happens when your eyes don't produce enough tears, or the tears you make are poor quality and evaporate too fast to keep the eye surface comfortable. It's one of the most common reasons people visit an eye doctor.
Symptoms
- A gritty, sandy feeling
- Burning or stinging
- Redness
- Episodes of watery eyes
- Sensitivity to light
- Blurred vision that improves with blinking
- Discomfort wearing contact lenses
Causes & risk factors
- Age over 50
- Meibomian gland dysfunction (blocked eyelid oil glands)
- Hormonal changes
- Long screen time with reduced blinking
- Dry, dusty, or air-conditioned environments
- Certain medicines (antihistamines, some BP drugs)
- Autoimmune conditions (Sjögren's, rheumatoid arthritis, thyroid disease)
- Previous eye surgery, including LASIK
Diagnosis
- Slit-lamp examination of eyelids, tear film, and eye surface
- Tear break-up time (TBUT) test
- Schirmer test — measures tear quantity
- Surface staining with special dyes
Treatment options
- Artificial tears (lubricating drops)
- Preservative-free drops for frequent use
- Warm compresses and eyelid massage
- Eyelid hygiene
- Prescription anti-inflammatory drops for moderate-severe cases
- Punctal plugs to keep natural tears on the eye longer
When to seek urgent care
See an eye doctor promptly for sudden severe pain, significant light sensitivity, a noticeable vision change, or redness that doesn't improve with lubricating drops.
Frequently asked questions
Is dry eye permanent?
For many it's a manageable, long-term condition rather than a one-time cure — but symptoms can usually be controlled well.
Can dry eye affect my vision?
Mild dry eye often causes blurry vision that clears with blinking; untreated severe cases can damage the eye surface and affect vision more persistently.
Are over-the-counter drops safe every day?
Preservative-free artificial tears are generally safe for frequent use. "Redness-relief" drops with decongestants are not meant for long-term everyday use.
