Canada ranked third in the world for the levels of stress, anxiety and sadness its adult citizens have felt over the course of the coronavirus (COVID-19) pandemic.
In Lenstore’s latest research, the team analyzed statistics on global health issues aside from COVID-19, such as vision loss, obesity rates, smoking, HIV cases and mental health disorders.
In its report, the contact lenses company writes that "Our research found that if the population of the world was 100 people, 6 would experience vision loss, 7 would have diabetes, 23 would be obese and another 23 would-be smokers.
"This leaves just 41 people who are either healthy, or more likely living with other forms of health conditions such as cancer or heart disease."
The company breaks the research down into health issues by country as well as by analyzing global statistics across regions. In total, it collected data across more than 10 health metrics for 24 countries around the world.
Recording this data as a percentage where possible, it ranked each country to show which are experiencing the highest levels of health concerns.
