causes of pain behind eye
Common causes of pain emanating from the front surface of the eye or inside the eye include: Corneal foreign body. Not surprisingly, what often causes a foreign body sensation in the eye is an actual foreign body.
Blepharitis: Inflammation or infection of the eyelid that causes irritation or pain. Conjunctivitis (commonly called pink eye): Inflammation of the conjunctiva caused by allergies or infections (viral or bacterial); blood vessels in the conjunctiva become engorged, and the normally white part of the eye looks red.
