Research suggests a link between myopia (nearsightedness) and higher than average IQs. However, not everyone who wears glasses has myopia. There are several different vision problems that wearing glasses can correct.
If you wear glasses I've got some good news: you may well be smarter than the average person. A new study published in the journal Nature Communications has found that needing to wear glasses is associated with higher levels of intelligence.
IQ correlates positively with family income, socioeconomic status, school and occupational performance, military training assignments, law-abidingness, healthful habits, illness, and morality.
There may be similar genes affecting eye size or growth (associated with myopia) and neocortical size (possibly associated with IQ)". Conclusions: The conducted clinical observations suggest that children with myopia may have a higher IQ.
Eyesight can be heavily influenced by genetics, while there are also environmental factors that can determine how good our eyesight will be.
Good eyesight is clearly better than poor eyesight, but it is fun to appreciate the advantages of poor eyesight, such as: longer life, better balance, and better presentation skills. Enjoying these advantages makes life more fun for you and those around you.
It seems that the best eyesight ever reported in a human was in an Aborigine man with 20/5 vision! To give you an idea of how clear and far he could see, his vision measurement compares to the natural sight of eagles. From 20 feet, he could perceive the fine details that most people can only see from 5 feet away!
“When people have vision loss, they change the way they live their lives. They decrease their physical activity and they decrease their social activity, both of which are so important for maintaining a healthy brain,” Dr. Swenor said. “It puts them on a fast tack to cognitive decline.”
The recent myopia boom is attributed primarily to the educational pressure in Asian countries, which prompts children to read for long hours, often under poor lighting and on computer screens. This practice severely limits the time spent outdoors and reduces exposure to sunlight and far vision.
Hyperopia tended to be more common in autism (19.5%), PDD-NOS (21.6%), and other disorders (42.1%) than in Asperger syndrome (7.14%), whereas myopia was more common in Asperger syndrome (17.9%) than autism (9.1%) and PDD-NOS (5.4%).
Empirical evidence suggests that especially parental education, parental income, and maternal IQ are important predictors of intelligence.
While there are many signs to indicate someone may be highly intelligent, the most common are a pleasant attitude and hardworking nature, excellent memory and recall capacity, good decision-making and problem-solving skills, high curiosity, good language proficiency, and high emotional intelligence.
Eyeglasses that make the man
Albert Einstein: The German-born physicist and Nobel Prize winner was best known for his massive mind and unkempt mane, but the genius also wore clear round plastic frames that hung low, as if he couldn't be bothered to get them fitted.
Geniuses Think Metaphorically
Metaphors and analogies are absolutely critical to the process of visual thinking. In fact, at least 20 percent of the visual thinking techniques we will discuss in future posts are built upon metaphors and analogies.
What is the link? The relationship between intelligence and vision, as well as the other health issues, is due to a genetic overlap between them. That said, while there is a correlation between intelligence and poor vision, scientists have not determined any cause to link the two.
Among all ethnic groups, Black Americans suffer the most from glaucoma and other eye diseases. In 2011, the Glaucoma Research Foundation found that glaucoma is the primary cause of blindness among African Americans.
2. The prevalence of myopia in Singapore is among the highest in the world, with 65 percent of our children being myopic by Primary 6, and 83 percent of young adults being myopic. As such, Singapore is often labelled as the “Myopia Capital of the World”.
Singapore is believed to have the highest prevalence of myopia in the world; up to 80% of people there have myopia, but the accurate figure is unknown. China's myopia rate is 31%: 400 million of its 1.3 billion people are myopic. The prevalence of myopia in high school in China is 77%, and in college is more than 80%.
Impaired concentration and focus, or the feeling that your brain is shrouded in fog, can be a sign of an undiagnosed, untreated, or undertreated vision problem. . Patients who have problems with concentration or focus may be able to improve their ability to attend through nutritional therapy, vision therapy and / or ...
Individuals with vision impairment are also more likely to experience restrictions in their independence, mobility, and educational achievement, as well as an increased risk of falls, fractures, injuries, poor mental health, cognitive deficits, and social isolation.
The visual system, which controls eyesight, is the largest system in the brain and can directly affect many functions of thinking, memory and cognition. We acquire information about our environment through our senses and vision plays one of the most important roles in cognition.
Rhinoceroses
Even though rhinos can charge up to 30 miles per hour, they can't distinguish between a human and a tree at 15 feet. Unless rhinoceroses can clearly hear and smell you, they have no way of knowing where you are in physical space.
If you encounter an aggressive lion, stare him down. But not a leopard; avoid his gaze at all costs. In both cases, back away slowly; don't run.
Eagles – Best Eyes in the Animal Kingdom
To put that into perspective, an eagle has the visual acuity of 20/5 – meaning that it can see at 20 feet what a human with 20/20 vision would need to be 5 feet away from to see. By this standard, an eagle's visual acuity is 4 times stronger than ours.
