COVID-19 lockdowns may be making more kids near-sighted
Observational study: A study in which the subject is observed to see if there is a relationship between two or more things (eg: the consumption of diet drinks and obesity). Observational studies cannot prove that one thing causes another, only that they are linked.
People: This is a study based on research using people.
US and Chinese scientists say being stuck indoors during the pandemic may be affecting some kids' eyesight, making them more near-sighted. They looked at eye tests of more than 120,000 children aged 6 to 13 years from 10 Chinese elementary schools, and say home confinement during the COVID-19 pandemic was associated with a significant shift towards near-sightedness among children aged 6 to 8 years. The prevalence of near-sightedness increased 1.4 to 3 times in 2020 compared with the previous 5 years, they add.
