Kids seem to spend endless hours on smartphones，computers and tablet computers these days.The best thing parents can do to prevent it is to encourage youngsters to spend more time outdoors in the sunlight.

There has been a massive rise around the globe in short-sightedness—or myopia(近视) as it's officially known—over recent decades.Myopia or shortsightedness is becoming more common.Lack of natural light seems to be the key issue.“The main factor seems to be a lack of exposure to direct sunlight，because children who study a lot and who use computers or smartphones or tablet computers a lot have less opportunity to run around outside and are less exposed to sunshine and because of  that  children seem to be at more risk of developing short-sightedness.”

Professor Hammond says，“It may be that there's no coincidence that in East Asian countries，the most myopic ones all relate to the maths league tables(排名表)．These kids are being pushed with very intensive education from a very young age and spend a lot of time indoors studying everything close up.Therefore the concern is that all close work—like playing with the iPad and iPhone—carries the potential that it could make them more short-sighted.”

The best thing to do，experts say，is to get children playing outside as much as possible.In a perfect world，probably on average across the week and the weekend，two hours a day outdoors is protective of becoming short-sighted in children.Healthy diet is really also important—in terms of getting oily fish，green vegetables，green leafy vegetables as much as possible.

“What we need to look at is ways of modifying the impact that these activities have on their visual development，”Professor Hammond said.“There are eye drops and other treatments to slow myopia progression.But in terms of preventing myopia itself，there isn't any data out there at the moment in terms of the question，‘Could the drops we use slow progression or stop myopia developing at all？’”

It is back-to-school time in the United States, which for many is bittersweet.The bitter part is saying goodbye to carefree, unscheduled summer days.The sweet part is saying hello to a new school year and school friends.

However, going back to school can also be a stressful time for children and families.Every kid must make the change from easy summer life to routines, schedules and homework.Parents might also stress about spending extra money for a new school year.They often need to pay school fees or to buy new school clothes, sports equipment, musical instruments and school supplies.

Back-to-school stress is different for different ages.Younger children may feel scared to leave their families.Making new friends and dealing with bullying can also cause stress for students.Older students may stress about their appearance, grades and getting into college.

A 2019 survey by the American Psychological Association found that teens in the US are now as stressed as adults.A high percentage of the teens surveyed say they are stressed about getting into a good college (83%) or deciding what to do after high school (69%) and financial concerns for their family (65%)．

However, parents, teachers and children can all help to make the transition back to school easier.

Mary Anne Aidala began teaching in the New York school system in l967.She retired 39 years later, in 2006.She is an award-winning teacher.She advises parents to focus on the basics—get enough sleep, eat healthy foods, and turn off electronics before bedtime.

“Well, the first thing they (parents) have to do is to get them (children) on a schedule of sleep habits.And they should also make sure they have a good breakfast to keep their brains alert.And maybe before they go to sleep every night they should start to read them a story or do something educational: so, they can start to reactivate their brains into using them.”
