Abstract
Purpose :
Prevalence of myopia is increasing in industrialized countries worldwide. The purpose of this study was to evaluate the prevalence of myopia in adults in France.
Methods :
National anonymized data including age at prescription, refraction, gender and district were collected from a group of 696 French opticians between 2013 to 2018. Myopia was defined by a spherical equivalent [SE] equal or less to -0.5D. After adjusting for the market share, the frequencies were adjusted to the total population of France.
Results :
The analysis included 3,185,025 adults (mean age 49 years, 57.62% of women). The mean SE was -1.00 D. The overall estimated prevalence of myopia, was 44.14%. The prevalence of low myopia (-0.5 to -2.9 D), moderate myopia (-3 to -5.9 D), high myopia (between -6 and -10 D) and very high myopia (<-10 D) were of 29.96 %, 11.34%, 3.44% and 0.74%, respectively.
Conclusions :
This research is the first French epidemiology study on myopia with a large sample size. This study, despite selection bias due to the source of the data, provides usefull epidemiological informations on the prevalence of myopia in France.
