People Who Wear Glasses Are Indeed More Intelligent, Genetic Study Reveals

Findings of a new genetic research suggest that people who wear glasses are indeed more intelligent. Researchers said this has something to do with the genes.

The participants had taken different thinking tests that were then summarized as general cognitive ability score.

All had genetic testing that examined their DNA and none of the people had dementia or a stroke.

The researchers identified 148 genomic regions that appeared to be linked to having better cognitive function - 58 of which have not been reported before. The study also found that those with higher cognitive function tended to live longer, have a decreased risk of specific types of cancer, and even had healthier hearts.

The researchers were not able to find out why there is a genetic correlation that exists between intelligence, poor eyesight, and cardiovascular health but cited the implications of their findings. "We also need to study our results closely to see what they can tell us about the possibility of understanding the declines in cognitive function that happen with illness and in older age", he said.

"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".
