Prevention and public awareness of myopia

Abstract

Myopia has become a Public Health issue, with prevalence rates that depend on age and geographical area, reaching the highest values in Asia. Thus, a recent review on the prevalence of myopia in children, measured with cycloplegia, established that the prevalence ranges from 10% in Africa to 60% in Asia, increasing in all areas every year. These results show the importance of taking action to prevent myopia.The main factors with strong scientific evidence to prevent myopia are increasing outdoor time and decreasing near‐work activities.Public awareness is an essential factor to stop the increase in the prevalence rates of myopia. However, the increase in scientific literature does not give us information about the sensitivity of the general population on a specific topic.Through the internet search trends analysis, we can find out how much interest myopia has in the population, analysing the most concerned countries and how the related queries are being carried out and increased.Thus, if we look for the search trends with the word “myopia” as “term search” in the last 10 years, we can see how the number of searches is increasing, reaching the maximum in 2022. China, Taiwan, and Hong Kong lead the searches on the Internet, reflecting how the higher prevalence in these areas has generated a greater concern. Concerning related queries, we find a high growth in interest caused by the inclusion of myopia among the diseases of the international classification of diseases of the World Health Organization, ICD 10, with an increase of 2000% in the searches. This search suggests that people interested in myopia are looking for reliable sources to collect information. Finally, it is remarkable that in the review of the related queries, we did not find the term prevention among the most performed searches, and treatment, cure, or control are queries that are in positions 20, 21, and 26 of those searches.Compared with other of the most established eye pathologies in society, we can see as myopia is still behind them. For instance, if we compare the searches of the term myopia, with glaucoma or cataract, 61% of the web searches are related to glaucoma, 43% to cataracts, and only 16% corresponded to myopia.In conclusion, even though scientific evidence alerts us about the increase in the rates of myopia and the importance of working on its prevention, there is still a long way to reach society to generate a clear awareness of myopia and the consequences of not taking action to prevent it.
