    The Surprising Reason for the Epidemic Rise in Childhood Myopia (Near-Sightedness)

    Experts had assumed that elevated rates of myopia (near-sightedness) are due to the many hours young people stare at computers and other screens.

    But a recent study published in JAMA Opthalmology suggests that a greater factor may be a side effect of all that screen-watching — it’s keeping children inside. Myopia rates among students have skyrocketed to 90% in some countries.

    This new study joins a growing body of research indicating that a lack of direct sunlight may reshape the human eye and impair vision.
