5. Foreign objects in the Eye
A jab in the eye caused by a foreign object can cause damage and also lead to infection after the immediate problem is taken care of. This is not only the case with a sizeable object, but can even involve something as simple as an eyelash.
In this case, the redness is often dismissed as the result of contact with the foreign object, but if it does not go away and is accompanied by other symptoms, it may be a sign that an infection is developing.
Pain, itchiness, eye discharge, and fever are indications that the intrusion of an object may have caused an infection.
