The feeling that something is in your eye can be caused by several reasons, including a foreign body like dust or an eyelash, corneal injury such as a scratch or abrasion, infections, inflammation, or dry eyes. Even without an actual object, dryness or irritation on the eye's surface can produce a sensation often called foreign body sensation. Other causes could be allergies, conjunctivitis (pink eye), blepharitis (eyelid inflammation), or eye conditions like pterygium or pinguecula. This sensation is typically accompanied by irritation, tearing, redness, or pain, depending on the underlying cause. If the feeling persists, it is advisable to consult an eye care professional for an accurate diagnosis and treatment. Dry eyes, which happen when the tears don't keep the eye surface moist enough, are a common cause. Corneal abrasions from scratches cause sharp discomfort and a sensation of something being stuck. Allergies and infections also cause redness, itching, and a gritty sensation. If the sensation is linked to an injury, infection, or persistent dryness, treatments might include lubricating eye drops, antibiotics, or other medical interventions as recommended by an eye doctor.
