Glasses Are Common
Glasses are a common sight in the United States, making sense because 61 percent of the U.S. population reported using either glasses, contact lenses, or some other kind of either reading or hearing aid in 2012. Something particularly noticeable because 61 percent in 2012 was a considerable jump from 57 percent in 2001. If that trend has held, the percentage of the U.S. population that uses such things would be even higher in the present time.
How Common Are Glasses Throughout the World?
Six in ten people in the world need to wear corrective eyeglasses. More and more people need glasses to see. The percentage of people needing glasses has steadily risen in recent years. Moreover, women wear glasses more often than men. A well-grounded claim supports this that more than a billion people need glasses but don't have them, which has become an essential point of focus for a wide range of non-profit organizations.
On top of that, the existing evidence suggests that myopia can show up in a population with surprising speed. A 1969 study showed that just 2 out of 131 adults in a group of Inuit people in northern Alaska had myopia compared to more than half of their children and grandchildren. Other populations that have transitioned to a modern lifestyle have seen a massive surge in need of glasses worldwide. It isn't clear why this has been happening. Some people have suggested changes in evolutionary pressure. However, this is a massive issue because the change has been happening too fast for that to have much explanatory power. Instead, a likelier line of speculation is that a difference between modern childhood and pre-modern childhood is causing a massive increase in myopia cases.
Regardless, those who wear glasses should know that they are in great company. To ensure that their glasses continue performing as needed, consider using Z Clear for regular cleaning.
