Eye Pain and Irritation
Why Is My Eye Painful and Irritated? Causes, Treatment, and When to Seek Emergency Care
Eye pain and irritation are among the most common reasons people seek emergency and routine eye care. While some causes are relatively minor, others require prompt evaluation to prevent vision loss.
Patients describe their symptoms in many different ways. Some experience burning, stinging, or a gritty sensation, while others have sharp pain, redness, tearing, blurred vision, or light sensitivity. These symptoms may affect one eye or both eyes and may develop suddenly or gradually.
Because eye pain and irritation can have many different causes, a comprehensive eye examination is often the best way to determine the problem and begin the appropriate treatment.
What Do Eye Pain and Irritation Feel Like?
Symptoms may include:
- Burning eyes
- Stinging
- Sharp eye pain
- Aching around the eye
- Scratchy sensation
- Feeling like something is in the eye
- Dry eyes
- Watery eyes
- Red eyes
- Blurry vision
- Light sensitivity
- Pain when blinking
- Pain while wearing contact lenses
- Eye fatigue
Some symptoms come and go, while others become progressively worse throughout the day.
Common Causes of Eye Pain and Irritation
Dry Eye Disease
Dry eye disease is one of the most common causes of chronic eye irritation and mild eye pain.
When the tear film becomes unstable, the surface of the eye becomes inflamed, causing:
- Burning
- Scratchiness
- Fluctuating vision
- Watering
- Foreign body sensation
- Eye fatigue
Many patients notice symptoms worsen after computer use or reading.
Eye Allergies
Allergies frequently cause:
- Itching
- Burning
- Redness
- Watering
- Puffy eyelids
Although allergies usually produce more itching than pain, severe allergic inflammation can cause significant irritation.
Contact Lens Problems
Contact lenses should never hurt.
Common causes of discomfort include:
- Dry eye
- Poor lens fit
- Overwear
- Protein deposits
- Sleeping in contact lenses
- Corneal injury
- Infection
Pain while wearing contact lenses should always be evaluated prompty.
Corneal Abrasion
A scratch on the cornea can cause:
- Severe pain
- Excessive tearing
- Light sensitivity
- Blurry vision
- Foreign body sensation
Corneal abrasions usually occur after trauma, rubbing the eye, or contact lens wear.
Foreign Body
Dust, eyelashes, sand, wood, or metal particles trapped beneath the eyelid can produce persistent irritation and pain until removed.
Blepharitis and Meibomian Gland Dysfunction
Inflammation of the eyelids commonly causes:
- Burning
- Dryness
- Itching
- Eye irritation
- Contact lens discomfort
Treating the eyelids often significantly improves symptoms.
Corneal Ulcer
A corneal ulcer is a serious infection that may occur in contact lens wearers.
Symptoms include:
- Severe pain
- Red eye
- Blurred vision
- White spot on the cornea
- Excessive tearing
- Light sensitivity
This is an emergency requiring immediate evaluation.
Uveitis
Inflammation inside the eye can produce:
- Deep aching pain
- Redness
- Light sensitivity
- Blurred vision
- Floaters
Prompt treatment is essential to prevent vision loss.
Acute Angle-Closure Glaucoma
Although uncommon, acute angle-closure glaucoma causes:
- Severe eye pain
- Blurred vision
- Halos around lights
- Headache
- Nausea
- Vomiting
- Red eye
This is a true medical emergency.
How Are Eye Pain and Irritation Diagnosed?
Your eye doctor may perform:
- Comprehensive eye examination
- Slit lamp examination

These tests help identify the underlying cause and determine the best treatment.

Frequently Asked Questions
Why is my eye painful and irritated?
The most common causes include dry eye disease, allergies, corneal scratches, contact lens problems, eyelid inflammation, infections, and foreign bodies.
Can dry eye cause pain?
Yes. Moderate to severe dry eye disease can cause burning, aching, and a foreign body sensation because of inflammation on the surface of the eye.
Why does my eye hurt when I blink?
Pain with blinking is commonly caused by a corneal abrasion, foreign body, dry eye disease, blepharitis, or an eyelid problem.
Should contact lenses hurt?
No. Contact lenses should be comfortable. Pain or irritation while wearing contacts should be evaluated promptly.
Can allergies cause eye pain?
Most allergies cause itching and irritation rather than severe pain. Significant pain may indicate another eye condition.
What should I do if something is stuck in my eye?
Do not rub your eye. Rinse it with sterile saline or clean water. If discomfort continues, seek prompt evaluation.
Is a painful red eye serious?
It can be. A painful red eye may indicate a corneal ulcer, uveitis, acute glaucoma, or another sight-threatening condition.
When should I go to the emergency room?
Seek emergency care for severe pain, sudden vision loss, chemical injuries, penetrating trauma, or a painful red eye with blurred vision.
Can screen time cause eye pain?
Yes. Prolonged screen use decreases blinking, which can worsen dry eye disease and lead to burning, irritation, and eye fatigue.
Why do my eyes burn and water at the same time?
Dry eye disease frequently causes reflex tearing. Although your eyes water excessively, the tears often lack the proper oil layer needed to keep the eye lubricated.
