According to the American Optometric Association (AOA), parents severely underestimate the time their children spend on digital devices. What follows is a press release issued by AOA that speaks to the need to monitor your child’s use of digital devices and suggests the guidelines to help prevent or reduce eye and vision problems associated with digital eye strain.
ST. LOUIS (July 22, 2014) — An AOA survey reports that 83 percent of children between the ages of 10 and 17 estimate they use an electronic device for three or more hours each day. However, a separate AOA survey of parents revealed that only 40 percent of parents believe their children use an electronic device for that same amount of time. Eye doctors are concerned that this significant disparity may indicate that parents are more likely to overlook warning signs and symptoms associated with vision problems due to technology use, such as digital eye strain.
Eighty percent of children surveyed report experiencing burning, itchy or tired eyes after using electronic devices for long periods of time. These are all symptoms of digital eye strain, a temporary vision condition caused by prolonged use of technology. Additional symptoms may include headaches, fatigue, loss of focus, blurred vision, double vision or head and neck pain.
Optometrists are also growing increasingly concerned about the kinds of light everyday electronic devices give off – high-energy, short-wavelength blue and violet light – and how those rays might affect and even age the eyes. Today’s smartphones, tablets, LED monitors and even flat screen TVs all give off light in this range, as do cool-light compact fluorescent bulbs. Early research shows that overexposure to blue light could contribute to eye strain and discomfort and may lead to serious conditions such as age-related macular degeneration (AMD), which can cause blindness.
When it comes to protecting eyes and vision from digital eye strain, taking frequent visual breaks is important. Children should make sure they practice the 20-20-20 rule: when using technology or doing near work, take a 20-second break, every 20 minutes and view something 20 feet away. According to the survey, nearly one-third (32 percent) of children go a full hour using technology before they take a visual break instead of every 20 minutes as recommended.
Additionally, children who normally do not require the use of eyeglasses may benefit from glasses prescribed specifically for intermediate distance for computer use. And children who already wear glasses may find their current prescription does not provide optimal vision for viewing a computer screen. An eye doctor can provide recommendations for each individual patient.
The AOA recommends every child have an eye exam by an optometrist soon after 6 months of age and before age 3. Children now have the benefit of yearly comprehensive eye exams thanks to the Pediatric Essential Health Benefit in the Affordable Care Act, through age 18.
