The COVID-19 pandemic has resulted in children spending more time on digital devices, which may have a long-term impact on their vision, including the risk of myopia.

Short-sightedness is a growing public health problem. Luckily, scientists are starting to find solutions.
Genes are important in predicting the risk of myopia, but they alone cannot explain the epidemic.
