Overview
If you think your horse has something in its eye, treat it as urgent enough to check promptly. Don’t try to rub it out or pick at it, because that can make the irritation worse. Sometimes it really is just dust, a bit of bedding, or a grass seed, but eye problems can look similar at first, so a calm check and quick action matter.
Things To Check
1. See whether your horse is squinting, keeping the eye partly shut, or rubbing the face more than usual.
2. Look for redness, tearing, swelling, discharge, cloudiness, or a visible speck on the eye or eyelid.
3. Check whether the problem started after turnout, stable cleaning, grooming, hacking, or windy weather.
4. Notice whether one eye is affected or both, as this can help narrow down what’s going on.
5. Gently look at the surrounding skin for cuts, swelling, or signs the eye has been knocked.
6. Check for signs of pain such as head tilting, blinking hard, or not wanting the head touched.
7. Make sure the horse can still see and is moving normally, especially if the eye looks very painful or the face is swollen.
Common Causes
The most common causes are dust, shavings, hay chaff, grass seeds, or small bits of dirt getting blown into the eye. Grooming debris or a flick from a branch can also cause irritation.
Sometimes the eye is irritated by a scratch on the surface, an eyelid issue, or a small knock that has made the eye water and squint. Less commonly, a more serious eye injury or infection may be involved, which is why it’s best not to assume it’s only a bit of grit.
What To Do
Keep your horse calm and in a well-lit area so you can look properly without rushing. If the object is loose and clearly sitting on the surface, you may be able to gently encourage it away with clean saline, but don’t touch the eye itself with fingers, cotton wool, or tools.
Prevent rubbing where you can, because that can worsen irritation. Keep the horse out of dusty bedding or windy turnout for now, and make a note of any change in swelling, discharge, squinting, or cloudiness. If the eye still looks sore, or you can’t clearly remove the irritant with confidence, contact your vet the same day.
When To Contact A Vet
Contact your vet promptly if the eye is very painful, the horse won’t open it, the eye looks cloudy, there’s blood, a cut, or a deep scratch, or you can’t see anything but the horse still acts as if something is stuck in there.
You should also get veterinary advice if the problem doesn’t improve quickly, gets worse, or keeps coming back. Eye injuries can change fast, and it’s safer to have them checked early.
