Do glasses make people smarter? Or does intelligence predict the need for glasses? Wearing glasses has always been associated with being smart. The stereotype, which can sometimes be offensive, has tagged many people with four-eyed, geek, nerd, and other similar labels. Those insults may have come out of clueless bullies.
People wear glasses for many reasons. However, they are most commonly used in correcting near-sightedness and far-sightedness. Normal vision occurs when light is focused on the retina, and the image becomes clear.
Far-sighted people see perfectly long distances but focus harder on close objects. The light is then focused on a point behind the retina, and the view appears fuzzy. Near-sighted people can see clearly at a close distance. But when focusing on objects further away, the light focuses on a point in front of the retina, and everything appears blurry.
Why do nerds wear glasses?
People like to be known as geeks, but not many like to think of themselves as nerds. So it turns out that over 41% of people are happy with being called a geek, which is almost double the number of people who aren’t offended by being labeled a nerd. The word nerd comes from an acronym for northern electric research and development and the people that work there. Regardless of the word nerd has always been used to describe the dull. They usually wear glasses and act like a fool! Are they fool or self-centric?
The Mainz University Medical Center researchers have conducted the first population-based study on nearsightedness. They found that environmental factors may have more to do with it than genetics. Regarding eyesight problems, nearsightedness is one of the most common afflictions worldwide. It can affect children from a very young age. But our eyeballs continue to grow well into adulthood. So even in the 30s, it can still get worse.
In more severe cases, it can lead to all kinds of complications, like retinal detachment, macular degeneration, premature cataracts, and glaucoma. So it’s best to figure out what causes this and how to prevent it. Unfortunately, the answer may not be the one. Researchers examined almost 5,000 patients with nearsightedness for their study and found myopia. The technical term for the affliction becomes more prevalent at the higher level of education.
- About 24% of the nearsighted patients had no formal high school education, compared to 35% of high school and vocational graduates and 53% of university graduates.
They found that nearsightedness increases for each year of school completed. Now it’s commonly accepted that genetics play a massive role in seeing, and that’s true to an extent. But this study also examined 45 genetic markers associated with myopia and found that even those have a way lower impact on the severity of the disease than education level. Most of the nerds are suffering for this reason.
So why is this happening? The current consensus is that the activities at school like reading, looking at a whiteboard, or using a computer rapidly deteriorate vision. But what can be done? After all, we can’t “cure” nearsightedness. We can only correct it. But even things like corrective lenses and contacts are largely unsuccessful.
Some recent studies have suggested that exposure to sunlight is the key to preventing myopia in children. So they recommend that kids spend at least 15 hours outdoors and limit their time with close-up activities, like TV and video games, to 30 hours a week.
Numerous studies have shown that people with a high IQ and higher education are more commonly linked to near-sightedness and the need to wear glasses. For example, in 2014, researchers in Germany found that near-sightedness becomes more common as the education level increases.
The researchers found that:
- 24 percent with no high school education or other training were nearsighted.
- About 35 percent of school graduates were nearsighted.
- 53 percent of university graduates were nearsighted.
Such studies only show a link between being near-sighted and being smart. They do not suggest that being near-sighted is the cause and being smart is the effect. Research suggests that the cause and effect relationship between being near-sighted and smart could go both ways. So glass is not the judgment of nerd people. They have specific reasons for wearing glass.
