I believe there isn't an exact figure for the number of people who use glasses at a worldwide level, as such a study is incredibly difficult to make considering you'd have to run surveys just about everywhere. However, according to a quote in Stanford University medical report (about 30% to 35% of people have some combination of nearsightedness and astigmatism, and an extra 20% has myopia. If you add both, about 55% of the world population has some vision defect that is usually corrected with glasses. Nonetheless, this figure does not indicate how many of those people actually wear glasses, as they may not be able to afford them, they might not realize they have poor vision, or they may have gotten laser surgery instead.
Pretty much everyone in the world use drugs.
