Experts say it's worth easing kids back into a regular sleep routine with the start of a new school year. A good night's sleep helps students stay focused and attentive in class. To get back on track, experts recommend setting earlier bedtimes a week or two before the first day of school — or gradually going to bed 15 minutes earlier each night. Don't eat a heavy meal before bed and avoid TV or screen time two hours before sleep. Instead, work in relaxing activities like showering and reading a story. Parents can adjust based on what works best for their child.

Digital screens are pervasive at work and in homes and schools stores. The American Optometric Association says an estimated 104 million Americans of working age spend more than seven hours a day in front of screens. All that screen time can take a toll. Too much exposure to screens can lead to dry eyes, blurry vision, headaches and watery eyes. Experts say taking frequent breaks to look in the distance can help alleviate symptoms. Using larger monitors and fonts, and adjusting screen position also can help.
