Some children spend hours every day on their smartphones. Why is this the case? Do you think this is a positive or a negative development?

It is becoming increasingly common that some youth

use

to use

their mobile

phones

for hours every day.

This

essay will look at the reasons behind

this

development and in my opinion , the fact that

this

phenomenon brings more disadvantages than advantages.

To begin

with,the main reason why kids use mobile

phones

for a longer time is because there are more and more functions on mobile

phones

than before.

As a result

, smart mobile

phones

are not only helping children to search for the knowledge and news that they want, but

also

contain interesting social media and games,

while

students

do not have a long time for entertainment ,so they get addicted to these electronics because they can have fun easily and quickly on the internet.

However

, The drawbacks of young people using smartphones for long times every day are always more than it benefits first of all,using mobile

phones

too much will affect children‘s health.The most important problem is that mobile

phones

will cause harm to their eyes so that they can not see the objects around them clearly and must be wearing glasses.

This

will make their life inconvenient.

For instance

,a research group once do research on

students

in a middle school and found that the longer these

students

used their mobile

phones

, the worse their eyesight they have.

Secondly

，smartphones will distract

students

and may have a negative impact on their academic performance.There is not only free knowledge on mobile

phones

but

also

more attractive other things,

such

as games and short videos. These things will distract them and make them unable to focus on their study. in conclusion，from my perspective, youth love mobile

phones

because of their interesting functions. The phone would cause negative effects on their physical health and academic performance.
