A new study indicates that air pollution may harm children’s eyesight, while fresh air may help protect and improve their eyesight.
According to researchers in the PNS Nixes patrol, exposure to air pollutants – specifically nitrogen dioxide and micro particles (BM 2.5) – was associated with the extent of children’s ability to see without glasses.
It is known that genetic factors and lifestyle, such as spending time in front of electronic devices screens, play a major role in developing children with short -sightedness, as distant things appear blurry.
Using advanced machine learning techniques to study exposure to air pollution in approximately 30,000 children of school age, the research team discovered that environmental factors are also important.
After taking into account the other factors that cause nearsightedness, the researchers found that low levels of nitrogen dioxide and fine particles in the air are associated with improved visibility.
The researchers also found that primary school students and children with a simple to medium -sighted palace benefit from fresh air more than high school students or who suffer from severe palace, indicating that early intervention before the exacerbation of vision problems can cause a difference.
The study was unable to prove that air pollution causes nearsightedness. However, Professor Zonjju Shi of the University of Birmingham in the United Kingdom, who led the research team in a statement that the study “is among the first studies that focused on air pollution as an important dangerous factor, with regard to short -sightedness in children, can be controlled.”
The researchers stated that the installation of air purification devices in the classroom, and the creation of “pure air areas” around schools to reduce traffic pollution, and to close the streets in front of cars during the delivery of children to and from school, may have a positive impact on eye health.
“The fresh air is not limited to the health of the respiratory system, but also includes visual health,” said Shi.
