If your eye hurts when you blink, you’re likely looking for answers. Pain is your body’s way of telling you something isn’t right. And we understand that the sharp, scratchy, or achy feeling every time you blink can be distracting and uncomfortable.
While the cause for your eye being in pain when you blink is often a minor issue like a bit of dust or dryness, persistent pain is a sign that it’s time for a comprehensive eye exam. Knowing what could be going on can help you find relief and peace of mind. Understanding common causes is a helpful first step.
Common Causes for Eye Pain When You Blink
Your eye might hurt for many reasons, from a tiny eyelash that’s out of place to mild irritation. Here are a few common culprits.
Something Is in Your Eye
It can feel like a big deal, but often the cause is a small particle of dust, dirt, or a stray eyelash. This creates a gritty feeling that’s more noticeable when you blink. Your eye’s natural reaction is to tear up to flush it out, but it’s essential to know how to safely handle a foreign object to avoid further irritation.
Dry Eye
When your eyes don’t produce enough tears to stay lubricated, your eyelid can drag across the surface. This friction may cause discomfort, burning, or a scratchy sensation. Dry eye is a common condition that can affect anyone.
Conjunctivitis (Pink Eye)
Pink eye is an inflammation of the clear tissue covering the white part of your eye. It can make blinking feel very uncomfortable and gritty. The cause can be several things:
- Viruses, often from a common cold
- Bacteria
- Allergies to things like pollen or pet dander
- Irritants like smoke or chlorine from a pool
An Eye Injury or Scratch
A scratch on the cornea, the clear front surface of your eye, is a common reason for sharp pain when blinking. This scratch can happen from a poke in the eye or from rubbing it too hard. Even contact lenses can sometimes cause a minor scratch.
Symptoms to Watch For
Along with pain when you blink, you might notice a few other signs. Pay attention to these symptoms, as they can help identify the cause of your discomfort. A sudden onset of these symptoms, especially with severe pain, may indicate an eye emergency.
- A feeling like sand or grit is in your eye
- Redness and swelling of the eyelid or eye itself
- Watery eyes or a thick discharge
- Scratchy or burning feelings
- Extra sensitivity to light
- Blurred vision
Is Pain in One Eye a Serious Problem?
Pain in a single eye can feel alarming, but it often points to a problem specific to that eye, like an eyelash or a minor scratch. While many causes are simple to address, it’s also helpful to know which signs are red flags.
When It’s Likely a Minor Issue
If the pain is mild and feels more like irritation, it might be from a temporary cause like allergies or a bit of dust. These issues often improve on their own or with simple at-home care. Giving your eyes a little rest can also help.
Red Flags for Eye Pain
Some symptoms paired with eye pain suggest it’s time to see a professional. Let an eye doctor know if you experience any of the following:
- Sudden changes to your vision
- Severe or throbbing pain
- Pain accompanied by a fever or headache
- Seeing halos or rainbows around lights, which can be a symptom of glaucoma
Simple Tips for At-Home Relief
For minor irritation, a few simple actions may help soothe your eye. These steps can provide temporary relief while your eye heals.
- Use a warm compress: A clean, warm, damp cloth held over your closed eye for a few minutes can ease discomfort from dryness
- Try lubricating drops: Artificial tears can help flush out irritants and soothe dryness
- Avoid rubbing your eyes: Touching or rubbing can make irritation worse or even cause a scratch
- Take screen breaks: Give your eyes a rest from digital screens to reduce strain and dryness
Myths & Facts About Eye Irritation
There’s a lot of information about eye conditions, but not all of it is accurate. Let’s clear up a few common myths.
Myth: Pink Eye Spreads Through the Air
You can’t get pink eye just by looking at someone who has it. The contagious types of eye infections—bacterial and viral—spread through direct contact with eye secretions. This spread occurs when you touch a contaminated surface and then touch your eye.
Fact: Not All Pink Eye Is Contagious
If your pink eye is from allergies or chemical irritants, it is not contagious. You can’t pass it on to others. These types are a reaction to something in your environment.
Myth: All Eye Pain Requires Antibiotics
Antibiotics only work for bacterial infections. If your eye pain is caused by a virus, allergies, or a scratch, antibiotics won’t help. The correct approach depends on the actual cause of the pain.
When You Should See Your Eye Doctor
If the pain doesn’t improve after a day or 2 of home care, or if you have any of the red flag symptoms, it’s a good idea to schedule a visit. An eye exam is a straightforward way to find out exactly what’s causing the pain.
