Study finds wearing glasses actually makes you smarter

Researchers said this has something to do with the genes.

Researchers at the University of Edinburgh found that those who were more intelligent were almost 30 percent more likely to have genes indicating they require reading glasses.

The participants from the existing studies were all of European descent between the ages of 16 and 102, and those who exhibited higher intelligence were 28% more likely to need glasses and 32% more likely to be shortsighted.

All the volunteers were asked to submit their DNA samples, answer the questionnaires, and underwent tests created to give a measure of their general cognitive ability.

According to the findings, those with high cognitive ability scores were around 30 percent more likely to have genes associated with poor eyesight than others.

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.

"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", Davies said.

In addition to this, the study identified better health factors and less susceptibility to the most common health risks like hypertension, heart attack, depression and more thus having the ability to live longer.

Obviously not. A study conducted in the year 2010 shows that wearing fake glasses may look stylish but down the line, it makes wearers look more dishonest.

Davies and colleagues said that the results of their research could shed light on the declines in cognitive function, which occur when people get ill and as they get older.

"We are trying to map out constellations of genes that work together to create our amazingly complex and adaptive brain".
