Although lengthy study periods are associated with higher exam scores and can help to boost children's learning, these habits may also be having a negative impact on their vision, if taken to the extreme, a new study suggests.
Research published this month in The Lancet medical journal highlights that nearsightedness, also known as myopia, is prevalent in areas where children spend a lot of time indoors studying.
Analysing the data for Web MD, general paediatrician and eye expert Dr Roy Benaroch said that excessive reading itself does not seem to be the primary problem for rates of myopia increasing, but rather excessive time indoors is probably to blame.
"Sunlight itself seems to be necessary for normal eyeball growth and development. Children who spend almost all of their time indoors seem to have altered growth of their eyes, leading to an increased need for glasses," he added.
Bearing this in mind, Dr Benaroch said that parents now have scientific evidence to support their request for children to go and play outside and enjoy the fresh air, as it can boost their health.
