The sensation that something is in your eye when you blink is usually caused by a foreign object like an eyelash, dust, or a grain of sand. However, the feeling can also stem from various eye conditions, even when there's nothing physically present.
Common Causes
-
Foreign Objects: This is the most frequent reason. Small particles can easily enter the eye and cause irritation with each blink.
-
Dry Eyes: Insufficient tear production can lead to a gritty or foreign body sensation. When your eyes are dry, the eyelids rub against the surface of the eye, creating discomfort.
-
Blepharitis: Inflammation of the eyelids can cause crusty debris to form near the eyelashes, which can then irritate the eye.
-
Corneal Abrasion: A scratch on the cornea (the clear front surface of the eye) can feel like something is stuck in your eye.
-
Conjunctivitis (Pinkeye): Inflammation of the conjunctiva (the clear membrane covering the white part of the eye and the inside of the eyelids) can cause a gritty or burning sensation.
-
Corneal Ulcer: An open sore on the cornea can be quite painful and feel like a foreign body sensation.
What to Do
Here's what you can do to alleviate the discomfort:
-
Flush Your Eye: Gently flush your eye with clean water or a sterile saline solution. Use an eyedropper or a small cup to direct the fluid across your eye.
-
Blink Repeatedly: Blinking can help dislodge the irritant.
-
Pull Your Upper Eyelid Down: Gently pull your upper eyelid down over your lower eyelid. The lashes of your lower eyelid may help brush away the foreign object.
-
Seek Medical Attention: If the sensation persists, if you experience pain, blurred vision, or light sensitivity, consult an eye doctor. A medical professional can examine your eye to determine the cause and provide appropriate treatment. They can rule out serious conditions like corneal abrasions or infections.
When to See a Doctor
Consult an eye doctor if:
- The sensation persists after flushing.
- You experience pain, redness, or light sensitivity.
- Your vision is affected.
- You suspect a corneal abrasion or infection.
In summary, while the feeling of something in your eye when blinking is often due to a simple irritant, it's essential to consider underlying conditions if the sensation persists. Prompt medical attention can help ensure proper diagnosis and treatment.
