Genome Based Genetic Study Says Persons Wearing Glasses Are Intelligent


The scientists at the University of Edinburgh studied the genetic data of over 44,480 people, and found that those who were more intelligent were almost 30 per cent more likely to have genes indicating they require reading glasses.

They discovered that those with higher intelligence were 30% more likely to wear glasses or need contact lenses.

They say glasses make people look smarter and now there is research to back it up.

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

Analyzing the genetic data, scientists found that 148 genome-wide regions associated with a general cognitive function, including 58 genomic sites that hadn't previously been linked with intelligence.

Besides finding a link between eyesight and intelligence, researchers also found that genetic signature linked to increased cognitive function is also associated with better cardiovascular and mental health, reduced risk of lung cancer, and long life.

The study is said to be the largest genetic study of cognitive function and as a result, they have identified some genetic variations between the persons who wear glasses and un-wearers on the thinking capacity.

"Genetic studies of cognitive function are in their infancy, but this study is important in its sample size and power to detect novel associations between genes and traits", Natasha Sigala, a neuroscience professor who was not involved in the research, told Newsweek.

The results of the study could help understand the related cognitive decline in age and illness, The Telegraph reported. "I've been working on human intelligence for years, and it was a long time before I appreciated how health-relevant it is; our new study reinforces that appreciation". "In that sense, this study boldly goes further than anyone has gone before".
