TV screen from close range, increases the risk of myopia.

nearsighted parent/parents are vulnerable. 【M4】______

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?

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

head and eyestrain. [br] 【M5】
