Some people sit at a computer for work, others are active all day. I often come home and relax in front of the tv for an hour or two, or browse the net on my ipad.
Staring at a screen for a long time isn't good for your eyes, your posture or your relationships, yet we all do it. How long do you spend in front of a screen most days?
My work is done on line. So I do spend quite a bit of time on the computer or iPad during week days. I tend to avoid computers altogether during the weekend.
Well not in one sitting, but over the day maybe 7-8 hours a day, (this month.)
So maybe 2 hours on, 1 off...ect etc.
My right eye has started to twitch badly....so I have to stop my time going longer.
I probably spend about 4-5 hours a day as when I am not working, I seem to end up playing games on here. I also have the TV on and I guess that is another screen though posture is not so bad then as sitting in a comfortable chair.
