If your eye hurts when blinking, the problem may come from the eyelid, tear film or the clear front surface of the eye called the cornea. Sometimes the cause is relatively minor, such as dryness or a trapped eyelash. In other cases, pain while blinking can occur with a stye, eyelid inflammation, a corneal scratch or an eye infection. The type of pain and other symptoms, such as redness, discharge, swelling or blurred vision, can provide useful clues. Here are the common causes and signs that mean you should see an ophthalmologist.
Every blink moves your eyelid across the surface of your eye and spreads tears over the cornea. Normally, this movement should not hurt.
Pain can occur when the eyelid or eye surface becomes dry, swollen, inflamed or injured. A problem affecting only one small area may become particularly noticeable during blinking because the eyelid repeatedly passes over it.
The exact cause cannot be determined from pain alone, so it is useful to consider where the discomfort is coming from and whether other symptoms are present.
Dry eye occurs when your eyes do not produce enough tears or when the tear film evaporates or becomes unstable too quickly.
Without adequate lubrication, the eyelid moves across a drier eye surface, which may cause:
Long periods of computer or mobile phone use can make dryness more noticeable because people tend to blink less while concentrating on a screen.
A loose eyelash, dust particle, sand or another small object can become trapped beneath the eyelid or sit on the surface of the eye.
This can make every blink feel sharp or scratchy. The eye may also water excessively or become red, and you may constantly feel that something is stuck inside it.
Avoid rubbing the eye, as rubbing may push the particle across the cornea and cause a scratch.
A loose particle may sometimes be removed by blinking or gently flushing the eye with clean water or sterile saline. If you are unsure what to do, follow these first-aid steps when something gets into your eye.
An embedded object should not be removed at home. Persistent pain after the object has apparently come out also deserves examination because the cornea may have been scratched.
Conjunctivitis is inflammation of the conjunctiva, the thin membrane covering the white part of the eye and the inside of the eyelid.
Depending on the cause, it can lead to:
An inflamed eye may feel uncomfortable during blinking.
However, significant or deep eye pain is not something that should automatically be attributed to simple conjunctivitis. Pain accompanied by blurred vision or marked sensitivity to light should be evaluated by an ophthalmologist.
A stye is a tender, inflamed lump that usually develops near the edge of the eyelid. Since your eyelid moves every time you blink, pressure over the swollen area can make blinking painful.
A chalazion develops when an oil-producing gland in the eyelid becomes blocked. It is often less painful than a stye but may become tender or swollen when inflamed.
Do not squeeze, puncture or try to drain an eyelid lump yourself.
A clean warm compress may sometimes be recommended for eyelid gland blockage, but persistent, recurrent or worsening swelling should be examined to confirm the cause.
A corneal abrasion is a scratch on the clear surface at the front of your eye. Because the cornea is highly sensitive, even a small scratch can cause considerable discomfort.
Common causes include:
Symptoms may include sharp pain, redness, watering, sensitivity to light, blurred vision and the feeling that something remains trapped in the eye.
Blinking can make a corneal abrasion particularly uncomfortable because the eyelid repeatedly moves across the scratched surface.
Corneal abrasions are among the eye problems that may require professional eye injury treatment, particularly when pain persists, vision changes or contaminated material was involved.
Blepharitis is inflammation along the edges of the eyelids.
It may cause:
Since the inflammation affects the eyelid itself, blinking can feel sore or uncomfortable.
Blepharitis may also recur. Ongoing symptoms should therefore be properly assessed rather than repeatedly treated without determining what is contributing to the inflammation.
Spending several hours continuously looking at a computer, mobile phone or tablet can make the eyes feel tired, dry or achy.
Reduced blinking during screen use can contribute to dryness, while prolonged near focus may cause temporary eye fatigue.
Regular screen breaks and conscious blinking may improve mild discomfort related to digital eye strain.
However, ordinary eye strain is more likely to cause tiredness or aching than severe, sharp pain. If your eye hurts when you blink, especially in one eye or even after you have rested, another cause may need to be considered.
If your eye hurts when you blink and feels bruised, the discomfort may be coming from the eyelid or tissues surrounding the eye rather than from the eyeball itself.
Possible causes include:
If the bruised feeling started after being struck by a ball, hand, object or another source of impact, do not judge the injury only by how the eye looks from the outside.
Some injuries can affect structures inside the eye despite limited external bruising. Knowing the warning signs of blunt eye trauma can help you understand when an examination should not be delayed.
A bright red patch on the white part of the eye can sometimes be a subconjunctival haemorrhage, caused by bleeding from a small surface blood vessel. An uncomplicated subconjunctival haemorrhage is generally painless. Therefore, significant pain or a bruised sensation should not automatically be blamed on the visible red patch.
Minor irritation from dust, prolonged screen use or temporary dryness may improve once the trigger is removed.
Arrange an eye examination if the pain continues, keeps returning or becomes worse.
Seek prompt medical attention if eye pain occurs with:
What helps depends on the underlying cause.
For mild irritation without an injury or vision change, you can start by avoiding eye rubbing and temporarily removing contact lenses.
Lubricating artificial tears may help when dryness is responsible. A clean cool compress may soothe some forms of irritation, while a warm compress may be recommended for certain eyelid problems.
Avoid self-medicating with:
You should also avoid trying to remove an embedded foreign object yourself.
If the discomfort persists, a comprehensive eye examination can help determine whether the pain is coming from the eyelid, tear film, cornea or another part of the eye.
If your eye hurts when blinking, dryness or a trapped eyelash may be responsible, but persistent pain can also occur with a stye, blepharitis, corneal abrasion, infection or eye injury.
Pay particular attention to symptoms such as blurred vision, light sensitivity, increasing redness, swelling or pain following trauma. These signs may need more than home care.
If pain while blinking continues, recurs or begins affecting your vision or daily activities, book an appointment with Dr. Lav Kochgaway for a detailed eye examination and appropriate guidance.
Occasional mild discomfort may occur because of dryness, dust or temporary irritation. Persistent, significant or worsening pain is not something you should ignore, especially if you also have redness, discharge, light sensitivity or blurred vision.
Yes. When the tear film does not adequately lubricate the eye surface, the eyelid moves over a drier surface during blinking. This may cause burning, scratchiness, grittiness or soreness.
Pain in one eye may occur because of a trapped eyelash, foreign particle, stye, corneal abrasion, eyelid inflammation or another local problem. Persistent one-sided pain should be examined if there is no obvious temporary cause.
The duration depends on the cause. Minor irritation may improve relatively quickly once the trigger is removed, while a stye, corneal abrasion, inflammation or infection may persist longer. Pain that continues, worsens or occurs with vision changes should be evaluated rather than managed only at home.
