Abstract:Purpose
To re‐examine the changes with time in the underlying patterns of individual refraction at different ages, which have led to an increased prevalence of myopia in a population of Asian children.
Methods
Using published cross‐sectional longitudinal data, the frequency distributions of spherical equivalent refractive error (SE) in yearly cohorts of 6‐ and 12‐year‐old Japanese children during the period 1984–1996 were modelled in terms of ex‐ and bi‐Gaussian distributions.
Results
Both models suggested tha… Show more
