A foreign body in the eye can be a small object, which enters the eye or something which gets trapped beneath the eyelids or stick to eyes without essentially entering the eye, such as an eyelash. Foreign body may also be a sharp object, which penetrates the outer layer and enters into the eye. While any foreign body which is trapped under the eyelids, such as an eyelash or dirt, may not warrant a hospital visit, but any object which has penetrated the outer layer of the eye and has entered the eye requires immediate medical attention.
Causes of Foreign Body in the Eye
Almost every individual faces the problem of having a foreign body in the eye at some point in life. Common foreign bodies in the eyes are a small bit of sand, grit, dust, and even an eyelash. This occurs when something is blown into the eye, commonly occurring on a windy day, or when something falls into the eyes when looking upwards.
Foreign bodies actually entering the eye are not so common. They usually occur when an individual is hammering at something such as metal or wood, without wearing proper eye protection, leading to a small chip flying off and entering into the eye. This is a serious injury and requires immediate medical attention.
