Children can spend hours a day looking at computer screens and other digital

Children can spend hours a day looking at computer screens and other digital devices. Some eye care professionals say all that screen time has(26)led to an increase in what they call computer vision syndrome.
    Nathan Bonilla-Warford is an eye expert in Tampa, Florida, with VSP, Vision Service Plan, a big(27)insurance provider. He says he has seen an increase in problems in children. Dr. Bonilla-Warford says part of the problem is that children may be more likely than adults to(28)ignore early warning signs. According to Dr. Warfod, even if their eyes start to feel(29)uncomfortable or they start to get a headache, children are less likely to tell their parents, because they don’t want to have the game or the computer or whatever(30)taken away. He says another part of the problem is that people(31)blink less often when they use digital devices.
    The average person who uses a computer or an electronic device blinks about a third as much as we normally do in everyday life. And so that can(32)result in the front part of the eye drying and not staying moist and protected like normal.
    Eye doctors offer suggestions like following what is known as the 20/20/20 rule. Every twenty minutes, look away twenty(33)feet or more for at least twenty seconds from whatever device you’re using. Other suggestions include putting more distance between you and the device and using good lighting. Of course, another way to avoid eye(34)strain is to spend less time looking at screens. Many experts say children should spend no more than two hours a day using(35)digital devices—with no screen time for children under two.
