Corneal abrasion:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
A corneal abrasion usually results from a foreign body, such as a cinder or a piece of dust, dirt, or grit that becomes embedded under the eyelid. Even if the foreign body is washed out by tears, it may still injure the cornea. Small pieces of metal that get in the eyes of workers who don’t wear protective glasses quickly form a rust ring on the cornea and cause corneal abrasion. Such abrasions also commonly occur in the eyes of people who fall asleep wearing hard contact lenses or whose lenses aren’t fitted properly.
A corneal scratch produced by a fingernail, a piece of paper, or other organic substance may cause a persistent lesion. The epithelium doesn’t always heal properly, and a recurrent corneal erosion may develop, with delayed effects more severe than the original injury.
In the United States, corneal abrasions are a common ophthalmologic cause of emergency department visits. Incidence is highest among younger, physically active individuals; corneal abrasions are rare in elderly people.

About prevalence and incidence statistics:
The term 'prevalence' of Cornea disorders usually refers to the estimated population
of people who are managing Cornea disorders at any given time.
The term 'incidence' of Cornea disorders refers to the annual diagnosis rate,
or the number of new cases of Cornea disorders diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
