This map shows us what percentage of each country’s population wears glasses. More specifically prescription glasses. That means non-prescription sun glasses are not included.
So how about people wearing contact lenses? People that wear both contact lenses and glasses are included. People that wear only contact lenses are not included.
So how about statistics on people that wear only contact lenses? Well, there are statistics on people that wear contact lenses only, but I don’t know the methodology. The above data comes from Statista and sadly Statista is purposefully vague about the methodology and source. When checking the numbers of people that wear glasses with some of the data from the countries themselves, it seemed to match quite well. For the contact lenses, this was not the case. Therefore, I feel confident to use the data one the share of people that wear glasses, but not on the share of people that wear only contact lenses. This is quite a bummer, as I have a feeling that the low number of people wearing glasses in some countries, can be explained by a higher number of people that wear contact lenses. This is probably the case for Sweden and the Netherlands, but I can’t confirm that.
