TV screens both at school and at home. Scientific 【M2】______
studies show an epidemic of myopia (also known as

faster in many countries. Doctors warn that sitting too close
to a computer, especially fixes your eyes at a computer or【M3】______
TV screen from close range, increases the risk of myopia.
The cause of myopia is difficult to explain in simple

screens is one of the reasons, others say children born to
nearsighted parent/parents are vulnerable. 【M4】______
Can genes or the environment, or a combination of two 【M5】______
explain the growing prevalence of myopia across many
countries? How can parents understand what causes myopia
and the risks it poses to their children’s eyesight?
Children suffering from myopia have trouble seeing
close objects clearly. The eyeball is thought to become 【M6】______
longer, because of which less effort is needed to see up
close. Moreover, the elongated eye can no longer focus on 【M7】______
distant objects.
Symptoms of myopia are rarely noticed in early 【M8】______
childhood. Myopic children must hold books very close to 【M9】______
their face or may not be able to read the writing on the
blackboard in school. They may squint and complain of 【M10】______
head and eyestrain. [br] 【M5】
