Cognitive Ability Influences Myopia Less Than Education Does, According to New Study

myopiaMyopia, or short-sightedness, is a sight problem affecting many adults and children worldwide. Studies on what influences this problem are common, and previously a strong link had been found between cognitive ability and myopia.

Those with higher levels of education have previously been found to be more at risk for myopia than those who do not attend university. Questions raised by this study was whether the level of individual intelligence is a key influencer in myopia, or simply the level of education.

A new study by a team from the Mainz University Medical Center aimed to answer just that question. It has found that environmental factors including sports, recreation and education, actually have more of an influence on myopia than fluid cognitive ability. This overturns what was previously thought about the disorder and may open new pathways for research into new solutions or prevention.

According to Quradia, cognitive ability is a good indicator for myopia, but the main factor may be the level of education rather than the IQ of the individual. Those who attain higher education tend to have high IQs, and this link may have affected the results of the previous study in which it was not considered.

The study assessed 4000 subjects between the ages of 40 and 79, all of whom suffer from myopia. A direct correlation was found between the severity of the myopia and the level of education of the participant, rather than their IQ.

This new study was one of the largest myopia studies conducted so far and shows promising results indicating the causes of myopia. New results can change the way that myopia is treated, and more research will be conducted in the future about the factors which influence myopia within higher education, such as high volumes of work with computers or books.
