It is not just a stereotype anymore, scientists have proven that intelligent people are more likely to have poor visions, which makes them wear glasses.
A research has proven that people who wear glasses are more intelligent than people who have 20/20 vision. The research was carried out at the University of Edinburgh, where researchers found a correlation between poor vision and higher intelligence while conducting the world’s largest cognitive function study.
300,486 people were part of the analysis on genetics with ages between 16 and 102, this data was collected from 57 different studies from all over the world. Participants were part of various thinking tests and the results were then converted into a general cognitive ability score.
People who got more scores were thirty percent more likely to have a poor vision, thus required glasses, compared to the people who scored badly. The study also showed a correlation between high cognitive ability and genes known to play a crucial role in good cardiovascular health. This study is believed to help with Alzheimer’s disease. Researchers found 148 genes linked to having better-thinking skills, such as memory, reasoning, the speed of mental processing and spatial awareness. 58 of these genes were never reported before this study.
The team said these results could help to understand the depreciation in cognitive function that comes with diseases such as dementia.
Dr Gail Davies, of University of Edinburgh’s Centre for Cognitive Ageing and Cognitive Epidemiology, who led the analysis, said: ‘This study, the largest genetic study of cognitive function, has identified many genetic differences that contribute to the heritability of thinking skills. The discovery of shared genetic effects on health outcomes and brain structure provides a foundation for exploring the mechanisms by which these differences influence thinking skills throughout a lifetime.’
Higher intelligence is also linked to better heart health, mental health, less risk of getting lung cancer, and longevity. The participant’s DNA was also examined and no of them had dementia or a stroke in their entire life.
This study was published in Nature Communication and had researchers from various parts of the world.
