to a computer, especially fixes your eyes at a computer or 【S3】______
TV screen from close range, increases the risk of myopia.

parent/parents are vulnerable. 【S4】______

longer, because of which less effort is needed to see up
close. Moreover, the elongated eye can no longer focus on 【S7】______
distant objects.

childhood. Myopic children must hold books very close 【S9】______
