Out of all of the participants with myopia, in 2016, 90.1% had low myopia, 8.2% had medium myopia, and 1.7% had high myopia. On the other hand, in 2017, the percentage of children with low myopia was 89.1%, with a slight increase in the moderate myopia rates (9%) and the high myopia rates (1.9%). Likewise, there was an increase in the number of individuals who used glasses, from 70.6% in 2016 to 81.5% in 2017. In relation to this and with regards to the prevalence of myopia in the different autonomous communities, statistically significant differences have been found (p ≤ 0.001).
