During the winter months, children may be inside for longer periods and use screens more often. Children’s screen time has become a concern for many parents and educators.
Digital screens have become a common part of a child’s world, being used for interactive play, reading, learning, and to socially connect. The daily time a child spends viewing a digital screen (including a cell phone, tablet, laptop, computer, TV, or gaming screen) can add up quickly. Increased time using digital devices, especially when held close to the child’s face, can make undiagnosed vision problems worse, or create new symptoms.
Screen time also affects academic achievement. For example, a 2025 study in Canada involving 3,322 third grade students and 2,084 sixth grade students found that higher levels of screen time were associated with lower academic achievement in elementary school. Each additional hour of daily screen time was associated with 9%-10% lower odds of achieving academic levels in grade 3 reading and grade 6 math. Find more information on this study here.
Leaders in children’s health encourage families to monitor a child’s use of digital devices. Families can also create a Family Media Plan to reduce the impact of long-term use of digital devices on their child’s health.
Prevent Blindness and the National Center for Children’s Vision and Eye Health offer a free, downloadable poster in English and Spanish to guide best practices for children and digital screens. You can also find tips on Possible Signs of a Vision Problem in Children and information on myopia.
