How much time do you spend on your computers?

I spend way too many hours on the computer,usually my initial eight hours for work and then some in between sleeping,eating and a few other activities. Reasoning for this is because I have issues sleeping usually and then get woken up or something when I am trying to sleep and then can't go back to bed. In result to being up all the time and spending maybe over 16 hours a day on the computer I have horrible eyes and need glasses,and feel totally loss without some sort of connection to online via lap top or whatever other form to reach the internet,I'm a tech junkie and need to have access.
