The word 'prevalence' of Refractive Eye Disorders usually means the estimated population
of people who are managing Refractive Eye Disorders at any given time (i.e. people with Refractive Eye Disorders).
The term 'incidence' of Refractive Eye Disorders means the annual diagnosis rate,
or the number of new cases of Refractive Eye Disorders diagnosed each year (i.e. getting Refractive Eye Disorders).
Hence, these two statistics types can differ:
a short 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.
For more information see about prevalence and incidence statistics.
