Children’s Vision and the New Classroom Technology


Today's teachers make full use of computers, interactive whiteboards, digital devices, and even 3D technology to enhance the learning environment. Forty percent of teachers use computers for instruction, and at least one computer is in 97% of all American classrooms. That adds up to a lot of screen time for kids who also watch TV or play on the computer at home. But is it harmful to a child’s vision?

Parents are worried. Nearly a third say they’re concerned that computers and handheld electronics may damage their child’s eyesight. And 53% of parents believe 3D viewing may be harmful, according to a survey by the American Optometric Association (AOA). 

What does science say? So far, no evidence-based study has found that new technology itself causes vision problems, other than eye fatigue. Yet a 2009 study showed that the number of people with nearsightedness (myopia) has increased from 25% to nearly 42% in the last 30 years.

One theory: Today’s kids spend far more time doing "near work," such as texting, looking stuff up on cell phones, and playing computer games. And the increased timespent looking at things close up may have an effect. Other possible factors may include genetics and lack of outdoor activity.
