Researchers from the Mainz University Medical Center of the Johannes Gutenberg University Mainz in Germany have found the level of education a person has attained has a direct impact on whether or not that person will develop myopia.
Through their research investigators found that in isolation, cognitive ability plays a significant role in the development of myopia. However, when they took into account already identified potential influencing factors, the researchers found the number of years over which a person received their education exhibited a more direct and closer relationship with short-sightedness than cognitive ability. In other words, when comparing two equally intelligent people, the one who attended school for the longest and had better educational qualifications would be most likely to become myopic and experience more defective vision.
The study was recently published in the journal Investigative Ophthalmology & Visual Science.
