Should schools enforce stricter screen time limits for students?

Context

Schools worldwide are debating whether to impose stricter limits on student screen time, balancing concerns about digital distraction, eye strain, and mental health against the educational benefits of technology. The debate intensified in 2026 when major U.S. school districts like Los Angeles and Chicago announced formal restrictions, citing research suggesting excessive screen exposure may harm focus and development. The challenge lies in the murky science: while some studies link heavy screen use to attention problems, evidence remains inconclusive about optimal limits, leaving educators caught between precaution and pedagogical necessity.
