Essays / Computer addiction - Need writing topic ideas for my cause and effect essay [8]

Hi Madam,

I'm Mia. This Friday I have to turn in an outline for my Cause and Effect Essay. I had picked up a topic. It is Computer Addiction.

I think I just need to focus on the effects of this problem, is it right ?
I intend to give 2 effects.
Firstly, when people have computer addiction, they don't focus much on their other work. You know, they always look at the screen of their computer or laptop to see if there is any thing changed.

Secondly, some people are so addicted that they only turn of their computers when they go to bed. Spending all days with the network may cause their health to be weaker. For example, one day I got up and realized that I couldn't see anything clearly. Something had happened to my eyes and all I could do then was sleeping and waiting for myself recover. It took me about 2 days. That's horrible period !

Do you think they are reasonable or I need to find another effects ? Do I need to add any thing for those two effects above ?
