What mechanisms have been put in place to prevent or control the implication

The mechanisms that have been put in place is having a chair which is up straight so your directly viewing the screen so you don't have to strain your eyes also you can dull your screen down so the screen brightness ain't so bright and ain't directly damaging your eye and you can look at your screen longer which will prevent you getting a eye strains, the chair also helps because sitting up right don't cause back strains whereas if you were to lean back your back would strain. Also with headaches that will link to eye strains as they link if you have a eye strain it will affect your head then causing headaches, which then you can dull the screen down like i said and also you can take a couple of 10 minute breaks each hour so it gives your eyes time to adjust. 

Cyber bullying on the internet is when your getting harrased online, e.g- if you have facebook and you were getting bullied you would contently getting abusive inboxes and messages on your wall. 

Also you will need lots of training so you'll know all the health and safety and what it regardes, also the working policy is to make sure everyone is well looked after in the work place. 

When you send a photo  i would use bluetooth as it is free and cheap whereas if you sent it through a picture message it would cost and makes you go over your phone bill and if not on contract it will take your credit.
